About layers

Photoshop layers are like sheets of stacked acetate. You can see through

transparent areas of a layer to the layers below. You move a layer to position the

content on the layer, like sliding a sheet of acetate in a stack. You can also

change the opacity of a layer to make content partially transparent.

Transparent areas on a layer let you see layers below.

You use layers to perform tasks such as compositing multiple images, adding

text to an image, or adding vector graphic shapes. You can apply a layer style to

add a special effect such as a drop shadow or a glow.

See a Video tutorial: Understanding layers for an overview on working with

Layers.

Organizing layers

A new image has a single layer. The number of additional layers, layer effects,

and layer sets you can add to an image is limited only by your computer’s

memory.

You work with layers in the Layers panel. Layer groups help you organize and

manage layers. You can use groups to arrange your layers in a logical order and

to reduce clutter in the Layers panel. You can nest groups within other groups.

You can also use groups to apply attributes and masks to multiple layers

simultaneously.

Layers for non-destructive editing

Sometimes layers don’t contain any apparent content. For example,

an adjustment layer holds color or tonal adjustments that affect the layers below

it. Rather than edit image pixels directly, you can edit an adjustment layer and

leave the underlying pixels unchanged.

Page 2: Layeri Za Pocetnike

A special type of layer, called a Smart Object, contains one or more layers of

content. You can transform (scale, skew, or reshape) a Smart Object without

directly editing image pixels. Or, you can edit the Smart Object as a separate

image even after placing it in a Photoshop image. Smart Objects can also contain

smart filter effects, which allow you to apply filters non-destructively to images

so that you can later tweak or remove the filter effect. See Nondestructive

editing.

Video layers

You can use video layers to add video to an image. After importing a video clip

into an image as a video layer, you can mask the layer, transform it, apply layer

effects, paint on individual frames, or rasterize an individual frame and convert it

to a standard layer. Use the Timeline panel to play the video within the image or

to access individual frames. See Supported video and image sequence formats

(Photoshop Extended).

Layers panel overview

The Layers panel lists all layers, layer groups, and layer effects in an image. You

can use the Layers panel to show and hide layers, create new layers, and work

with groups of layers. You can access additional commands and options in the

Layers panel menu.

Filter layers (CS6)

At the top of the Layers panel, the filtering options help you find key layers in

complex documents quickly. You can display a subset of layers based on name,

kind, effect, mode, attribute, or color label.

Page 4: Layeri Za Pocetnike

Filter layers options in the Layers panel

1. Choose a filter type from the popup menu.

2. Select or enter the filter criteria.

3. Click the toggle switch to switch layer filtering on or

off.

To the top

Convert background and layers

When you create a new image with a white background or a colored background,

the bottommost image in the Layers panel is called Background. An image can

have only one background layer. You cannot change the stacking order of a

background layer, its blending mode, or its opacity. However, you can convert a

background into a regular layer, and then change any of these attributes.

When you create a new image with transparent content, the image does not

have a background layer. The bottommost layer is not constrained like the

background layer; you can move it anywhere in the Layers panel and change its

opacity and blending mode.

Convert a background into a layer

1. Double-click Background in the Layers panel, or

choose Layer > New > Layer From Background.

2. Set layer options. (See Create layers and groups.)

3. Click OK.

Convert a layer into a background

1. Select a layer in the Layers panel.

2. Choose Layer > New > Background From Layer.

Any transparent pixels in the layer are converted to

the background color, and the layer drops to the

bottom of the layer stack.

Page 5: Layeri Za Pocetnike

Note: You cannot create a background by giving a regular layer the

name, Background—you must use the Background From Layer command.

To the top

Duplicate layers

You can duplicate layers within an image or into another or a new image.

Duplicate a layer or group within an image

1. Select a layer or group in the Layers panel.

2. Do one of the following:

Drag the layer or group to

the Create a New Layer

button  .

Choose Duplicate Layer or

Duplicate Group from the

Layers menu or the Layers

panel menu. Enter a name

for the layer or group, and

click OK.

Duplicate a layer or group in another image

1. Open the source and destination images.

2. From the Layers panel of the source image, select one

or more layers or a layer group.

3. Do one of the following:

Drag the layer or group

from the Layers panel to

the destination image.

Select the Move tool  ,

and drag from the source

image to the destination

image. The duplicate layer

or group appears above

the active layer in the

Layers panel of the

Page 6: Layeri Za Pocetnike

destination image. Shift-

drag to move the image

content to the same

location it occupied in the

source image (if the source

and destination images

have the same pixel

dimensions) or to the

center of the document

window (if the source and

destination images have

different pixel dimensions).

Choose Duplicate Layer or

Duplicate Group from the

Layers menu or the Layers

panel menu. Choose the

destination document from

the Document pop-up

menu, and click OK.

Choose Select > All to

select all the pixels on the

layer, and choose Edit >

Copy. Then choose Edit >

Paste in the destination

image. (This method

copies only pixels,

excluding layer properties

such as blending mode.)

Create a new document from a layer or group

1. Select a layer or group from the Layers panel.

2. Choose Duplicate Layer or Duplicate Group from the

Layers menu or the Layers panel menu.

3. Choose New from the Document pop-up menu, and

click OK.

Sample from all visible layers

The default behavior of the Mixer Brush, Magic Wand, Smudge, Blur, Sharpen,

Paint Bucket, Clone Stamp, and Healing Brush tools is to sample color only from

pixels on the active layer. This means you can smudge or sample in a single

layer.

 To smudge or sample pixels from all visible layers with these tools, select Sample All Layers from

the options bar.

To the top

Change transparency preferences

1. In Windows, choose Edit > Preferences > Transparency & Gamut; in

Mac OS, choose Photoshop > Preferences > Transparency & Gamut.

2. Choose a size and color for the transparency checkerboard, or choose

None for Grid Size to hide the transparency checkerboard.

3. Click OK.

Create and manage layers and groups

Create layers and groups

A new layer appears either above the selected layer or within the selected group

in the Layers panel.

Create a new layer or group

1. Do one of the following:

(See Blending modes.)

Opacity

Page 9: Layeri Za Pocetnike

 

Specifies an opacity level for the layer or group.

Fill With Mode-Neutral Color

 

Fills the layer with a preset, neutral color.

Note: To add currently selected layers to a new

group, choose Layer > Group Layers, or Shift-click the

New Group button at the bottom of the Layers Panel.

Create a layer from an existing file

1. Drag the file icon from Windows or Mac OS onto an

open image in Photoshop.

2. Move, scale, or rotate the imported image. (See Place

a file in Photoshop.)

3. Press Enter or Return.

By default, Photoshop creates a Smart Object layer.

To create standard layers from dragged files, deselect

Place Or Drag Raster Images As Smart Objects in the

General preferences.

If the placed file is a multilayer image, a flattened version appears on

the new layer. To instead copy separate layers, duplicate them in another

image. (See Duplicate layers.)

Create a layer with effects from another layer

1. Select the existing layer in the Layers panel.

2. Drag the layer to the Create a New Layer button at

the bottom of the Layers panel. The newly created

layer contains all the effects of the existing one.

Convert a selection into a new layer

1. Make a selection.

2. Do one of the following:

Choose Layer > New >

Layer Via Copy to copy the

selection into a new layer.

Page 10: Layeri Za Pocetnike

Choose Layer > New >

Layer Via Cut to cut the

selection and paste it into

a new layer.

Note: You must rasterize Smart Objects or

shape layers to enable these commands.

To the top

View layers and groups within a group

 Do one of the following to open the group:

Click the triangle to the left of the folder icon  .

Right-click (Windows) or Control-click (Mac OS) the

triangle to the left of the folder icon and choose Open

This Group.

Alt-click (Windows) or Option-click (Mac OS) the

triangle to open or close a group and the groups

nested within it.

To the top

Show or hide a layer, group, or style

 Do one of the following in the Layers panel:

Click the eye icon   next to a layer, group, or layer

effect to hide its content in the document window.

Click in the column again to redisplay the content. To

view the eye icon for styles and effects, click the

Reveal Effects In panel icon  .

Choose Show Layers or Hide Layers from the Layers

menu.

Alt-click (Windows) or Option-click (Mac OS) an eye

icon   to display only the contents of that layer or

group. Photoshop remembers the visibility states of

all layers before hiding them. If you don’t change the

visibility of any other layer, Alt-clicking (Windows) or

Page 11: Layeri Za Pocetnike

Option-clicking (Mac OS) the same eye icon restores

the original visibility settings.

Drag through the eye column to change the visibility

of multiple items in the Layers panel.

Note: Only visible layers are printed.

Photoshop, Layers 101 - By Colin Smith

Layers were introduced in Photoshop 3.0. This totally revolutionized Photoshop. For the first time you could do

complex compositions easily without having to be a channels guru. I remember before layers, if a client wanted to

make changes to a composition, or even change a font you were in big trouble.

There is a lot to layers and they will take some time to master. But they are not that difficult once you understand

how they work. In this tutorial I will explain the concept of layers, describe the features and walk you through a

simple tutorial. Along the way I will throw in a few cool tips to help you work faster and easier.

Part 1. What is a Layer?

A layer is simply one image stacked on top of another. Imagine I have a piece of paper and I paint it red. Then I

take a peice of clear celophaine and paint a yellow circle, and lay it over the paper. Now I take another peice of

cellophane and paint some blue type and laythat on top of the yellow circle. I now have a background (red) and 2

layers (yellow and blue.) Just like in the picture below.

 

A background with 2 layers.

This is how your image with would look on the screen or when printed. 

Broken apart so you can see how the layers work

Each layer stacks on top of the previous one.

That is it! The concept of layers is that simple. Photoshop uses the Layers Pallete to allow you to do this with your

images. More than one layer is called a composition.

Photoshop's layers Pallete is a powerful tool that allows you do many special things to your layed compositions.

Next we will look at the Photoshop 6 layers pallete.

The Layer Window

Normal Layer: Where your image layer is stored

Layer Effects (Styles): Special effects applied to your image layer. Noted by the little f. Each effect will be listed.

Here only the drop shadow is used, multiple effects may be used at once.

Page 12: Layeri Za Pocetnike

Type Layer: The same as an image layer, except this layer contains type that can be edited; (Change character,

color, font or size)

Background: Always locked, cannot be moved or have layer effects applied to it. The little icon of the padlock on

the right, indicates it is locked. Can be changed into a regular layer by simply double clicking on the thumbnail.

Thumbnail: A small picture of the layers contents.

Show/Hide Icon: If the eye is showing that layer is visible. Click on the eye and the layer will still be there but

invisible until you click on the eye again.

Layer Features

Blending mode: Changes the way the layers interact with each other. Experiment with the different modes.

Layer opacity: Adjusts how transparent each layer is. 0 is completely transparent, 100 is completely opaque.

Lock all: If the box is checked the layer is totally protected from any editing.

Lock Position: You can make any changes except for moving the image.

Lock Image pixels: You cannot draw on this layer if checked.

Lock transparent: You can paint on this layer but not where it is transparent.

Delete: Will delete an entire layer. Either Drag the thumbnail to the icon or select the layer* and click on the trash

can (delete icon).

*Selected layer highlighted -Type layer is currently selected

New Layer: Click to add a new blank layer. Or drag an existing layer thumbnail to create a duplicate.

New Adjustment layer: Allows non-destructive adjustment of colors to a layer. (Can be undone anytime, even

after closing document)

Create a new set: Allows you to organize your layers into folders. This new feature was on my wish list.

Layer mask: Allows you to paint away parts of your layer without damaging your original image.

Page 13: Layeri Za Pocetnike

Layer styles: Special effects for your layers. Beefed up version of the old layer effects. (Allows you to do cool

things with no effort)

Neprestano spominjemo izraze layer i maska. Mnogi od vas znaju što je to i čemu služi ali ovo je tutorial za vas početnike. Objasnit ću točno što je to, čemu služi i kako se koristi u ovom edukativnom tutorialu.

1. korak Prije svega, treba znati što je maska. Ona je upravo ono što joj i ime govori. Definira koji dio/dijelove sloja/layera ćemo vidjeti. Kao da stavimo skijašku masku npr. Ona će pokriti naše lice ali će ostaviti vidljive oči i usta. Naše lice je sloj a maska je... maska. Idemo odmah na primjere. Recimo da u photoshopu imamo otvorenu sliku sa dva sloja

SLIKA

2.korak "kutije" su iste veličine, tako da će se vidjeti samo zelena "kutija" pošto je ona layer2, dakle nalazi se preko layera1. Recimo da želimo vidjeti i dio crvene kutije. To postižemo sa "layer maskom". Izabrat ću zeleni sloj i add a layer mask te ću nacrtati veliki X preko njega. To daje photoshopu naredbu da pokaže što je ispod kroz oblik koji sam nacrtao

SLIKA

Idemo na praktično. 

3.korak idi na Create New Image i stvori dva sloja (layera). Ja koristim ove sa donje slike. Vidjet će se samo gornji layer ali ćemo dodati masku tako da se i neki dijelovi donjeg pokažu. Klikni na gornji layer i idi na Layer>Add Layer Mask>Reveal All 

SLIKA

4.korak Primjetit ćete da se nakon klikanja opcije reveal all vaša paleta sa layerima promijenila

SLIKA

5.korak Ovo je layer maska glavom i bradom, dame i gospodo. Primjetite da je bijela a da se naizgled vaš layer nije promijenio. Layer maska se sastoji od samo dvije boje; crne i bijele. Bijela govori da vidiš layer a crna da vidiš one layere ispod. Za primjer, nacrtat ću veliki X (sa paintbrushom) preko layer maske. 

SLIKA

6.korak Kao što vidite, na mjestu gdje sam nacrtao X, pokazao se donji sloj. Na masku možete crtati bilo kojim alatom dok god su boje koje koristite crna i bijela. Ako želite editirati masku, morate kliknuti BAŠ na nju a ne bilo gdje na sloj

SLIKA

7.korak Sada ćemo editirati masku. X sam popunio bijelom bojom tako da se opet pojavljuje samo čisti layer. Ovaj put sam obojao pozadinu oko vojnika crnom. Koristio sam manje četkice i pažljivo ga omeđio crnom. Fora je da - ako pogriješiš - uvijek možeš opet sve ispuniti bijelom pa ponovo

Page 14: Layeri Za Pocetnike

SLIKA

8.korak Negdje na početku, koristili smo opciju Reveal all. Sad gledajte primjer gdje ćemo koristiti opcijuHide All. Recimo da želite pretvoriti sliku u crno-bijelu ali da neki njeni dijelovi ostanu netaknuti. Dupliciraj layer (crtl+j) i promijeni donji sloj u crno-bijeli (grayscale). Zatim kliknite na gornji iLayer>Add Layer Mask>Hide All. 

SLIKA

9.korak Sad možete editirati layer masku i obojati paintbrushom u bijelo dijelove koje želite da budu vidljivi. Ovaj puta je maska crna a vi vidite donji layer umjesto onog gornjeg (sa maskom) jer je cijeli layer trenutno skriven

SLIKA

10.korak Sad ću obojati layer masku na dijelovima oko vrha vojnikovog oružja i oko vizira njegove kacige. Rezultat je 

SLIKA

11.korak Još ću pokazati jedan primjer a u njemu leži prava mož layer maski. Koristit ću gradient toolumjesto paintbrusha. Koristit ću originalnu sliku kao gornji sloj a istu tu sliku ću koristiti i kao donji, s tim da ću na donjem napraviti radial blur (filter > blur > radial blur) 

SLIKA

12.korak Na gornjem sloju sam otišao na Layer>Add Layer Mask>Reveal All . Uzeo sam Gradient Tool i koristio white to black (od boja. bijela se preljeva u crnu. to vidite gore, ispod File, Edit, Image...) i upaljen Radial. (od onih 5 ikonica, radial je druga. isto gore). Započeo sam na vojnikovoj glavi i povukao crtu negdje do pola slike (van od vojnika). Vidjet ćete kako krug "vene" iz bijele u crnu na samoj maski, na mjestu gdje sam povukao gradient. Ovo dozvoljava donjem layeru da se stapa, što smo dobili sa radialom i gradient toolom, umjesto da sam ga definirao paintbrushom. Upravo to je jedno od najmoćnijih obilježja layer maski; da se slojevi spajaju na bilo koji način koji poželimo. 

SLIKA

13. i zasad zadnji korak   Najbolji način da ovo shvatite je da uzmete neke slike pa se "igrate" s njima. Jednom kad shvatite logiku svega toga, vidjet ćete da je to primjenjivo u gotovo svakom projektu. 

Photoshop layers – kako i zašto ih koristiti

Sjećam se da mi je trebalo mnogo truda da svoju kći nagovorim da počne koristiti layere u

photoshopu. Dugo vremena sve je radila na istom layeru. Kada sam je upitala zašto tako radi, rekla

je da zaboravi otvoriti novi, a i da je previše layera zbunjuje   Ako i vi radite istu početničku grešku,

vrijeme je da je ispravite.

Što su zapravo photoshop layeri?

Page 15: Layeri Za Pocetnike

Layere možemo zamisliti kao listove prozirnog paus papira (ili prozirne folije) na našem stolu,

posložene jedan na drugome. Recimo da crtamo kućicu. Površina stola je naš “background layer” i

po stolu nećemo crtati   . Na jednom paus papiru ćemo nacrtati fasadu, na drugom vrata, na

trećem jedan prozor, na četvrtom drugi prozor i tako dalje…  Kada smo sve nacrtali, možemo prozor

premjestiti na drugo mjesto jer se prozor nalazi sam na svom posebnom papiru-foliji. Da smo sve

crtali na jednom papiru, ili nedajbože po stolu, to nebismo mogli, jel tako?

No, premještanje elemenata nije jedini razlog za korištenje layera. Pokazati ćemo to na

jednostavnom primjeru:

Korištenje photoshop layera

Otvorimo novi dokument u photoshopu. Idemo na window  / layers kako bismo otvorili docker

(karticu) sa layerima. Na našem dockeru sada imamo samo jedan “background layer” i na njemu se

nalazi mala ikonica lokota. To znači da je taj layer zaključan i da na njemu nemamo sve opcije koje

ćemo imati na drugim layerima. Kliknimo na njega desnom tipkom miša da bismo vidjeli mogućnosti

koje imamo (slika 1)

slika 1

Sada ćemo otvoriti još jedan layer, klikom na malu ikonicu na dnu dockera (slika 2)

Page 16: Layeri Za Pocetnike

slika 2

Sada ćemo na novom layeru nacrtati dva oblika i kliknuti desnom tipkom miša na taj novi layer.

Primjetiti ćemo da na tom layeru imamo mnogo više opcija nego što smo imali na background layeru

(slika 3)

slika 3

Sada ćemo ići na edit / transform (ctrl + T) i primjetiti ćemo da ne možemo smanjiti ili povećati samo

jedan element nego jedino oba. Također, ne možemo premjestiti samo jedan element, kao niti samo

jednom od njih promijeniti boju. To je zato što su oba elementa na istom layeru. (slika 4 i 5)

Page 17: Layeri Za Pocetnike

slika 4

slika 5

Sada ćemo taj layer odvući u kantu za smeće i ponovo nacrtati dva elementa, ali svaki na posebnom

layeru. Sada svakoga od njih možemo zasebno smanjivati, pomicati ili im mijenjati boju. Možemo i

mijenjati raspored layera tako da donji layer odvučemo iznad gornjeg ili obrnuto čime ćemo jedan

element postaviti ispred ili iza drugog . (slika 6)

Page 18: Layeri Za Pocetnike

slika 6

Organizacija layera u mape

Ne treba se bojati otvarati nove layere, radi lakšeg snalaženja možemo ih sortirati u mape. Nova

mapa otvori se klikom na malu ikonicu na dnu dockera sa layerima i u nju se odvuku svi layeri koji po

logici pripadaju u istu grupu. U jednoj mapi možemo imati i podmape.

Jedan layer , samo mapu ili mapu sa svim layerima u njoj možemo jednostavno izbrisati ; desni

klik /delete ili odvući u kantu za otpatke na dnu dockera.

Prilikom dizajniranja web stranice, dizajneri na jednom PSD dokumentu imaju i stotinjak layera, na

primjer, samo moj “ logotip ”  ih ima ih oko 35, složenih uredno u nekoliko mapa koje se sve zajedno

nalaze u jednoj mapi “logo”. (slika 7)

Page 19: Layeri Za Pocetnike

slika 7

Mape su praktične i stoga što cijelu grupu elemenata možemo isključiti i uključiti jednim klikom na

ikonicu sa lijeve strane ili premjestiti, a sve to nam ubrzava i olakšava rad.  (slika 8 )

slika 8

Dakle, slobodno otvarajte nove layere, za razliku od papira na vašem stolu, ovdje ne postoji opasnost

da ih iznenadni propuh razbaca uokolo 

Photoshop za početnike – 3 stvari koje ćete sigurno trebati

Page 20: Layeri Za Pocetnike

Kako zaokrenuti photoshop brush, kako proširiti sliku i kako stopiti dvije slike u jednu – to su tri pitanja

koje postavimo čim se počnemo igrati u photoshopu ili baviti dizajnom. Nije teško, pogledajmo kako se to

radi:

1)  ZAOKRETANJE PHOTOSHOP KISTA

Postoje nekoliko načina kako to možemo učiniti. Prvi je da kist stavimo na novi layer, zatim idemo na

image / transform / i mišem ga zaokrenemo u željenu poziciju.

Drugi način je da na tipkovnici pritisnemo Ctrl + T i na gornjoj traci prozora odredimo kut nagiba

(označen je malom ikonicom u obliku kuta ).

Treći način je prikazan ovdje: na novi layer, dakle, otisnemo željeni kist (slika 1)

slika 1

Otvorimo brush docker window   (slika 2) ili stisnemo F5

slika 2

Kliknemo na “brush tip shape” i upišemo kut (Angle) zaokretanja (slika 3)

Page 21: Layeri Za Pocetnike

slika 3

i gle čuda! 

slika 4

2) ŠIRENJE SLIKE U PHOTOSHOPU

Ok, našli smo fotografiju koju želimo koristiti recimo u headeru našeg novog dizajna za web stranicu.

Problem je da nam treba header recimo 960 px širok i maksimalno 300 px visok a fotografija je

podjednake širine i visine. I što sad? (slika 5)

slika 5

Problem možemo riješiti na nekoliko načina. Ako odabrana slika ima lijevu ili desnu stranu jednolične

boje ili gradienta možemo je rastegnuti.

Prvo pomoću marquee tool-a    označimo nekoliko rubnih pixela  ( slika 6)

Page 22: Layeri Za Pocetnike

slika 6

a zatim odaberemo edit / transform ili Ctrl + T i mišem rastegnemo označeni dio do željene širine.

(slika 7)

slika 7

I to je to. Ukoliko nam se pojave vodoravne linije možemo ih izgladiti pomoću “blur tool-a”   ( slika

8.)

slika 8

3) STAPANJE DVIJU FOTOGRAFIJA U JEDNU

Iako ovaj efekt danas više nije popularan u web dizajnu kao prije, još uvijek nam ponekada može

dobro doći. Koristiti ćemo upravo rastegnutu fotografiju za pozadinu i njoj ćemo dodati još jednu.

(slika 9 )

Page 23: Layeri Za Pocetnike

slika 9

Gornjem layeru dati ćemo “layer mask” tako da kliknemo na layer, a zatim na treću ikonicu slijeva

na dnu dockera sa layerima. (slika 10)

Kada layeru dodamo layer mask, uz ikonu slike na istom layeru pojaviti će se i ikonica layer maske.

Na nju moramo kliknuti i označiti je jer gradient dodajemo layer maski a ne slici! ( slika 10 – A )

Zatim ćemo odabrati gradient tool , namjestiti frontcolor crnu, a background color bijelu, odabrati

linear gradient “foreground to background” i isključiti “reverse” ako nam je uključen. (slika 11)

Držati ćemo pritisnutu tipku “shift” i mišem označiti područje slike na kojem želimo postepeni

prijelaz. (slika 12)

I naše dvije slike biti će savršeno stopljene.

Ukoliko želimo da se fotografija stapa po svim rubovima i bude okruglog oblika, možemo umjesto

linearnog gradienta upotrebiti “radial gradient”. Ili možemo napraviti nešto drugo:

Prvo gornjem layeru damo layer mask.

Zatim odaberemo front color crnu i izlijemo je na taj layer. Fotografija će sasvim nestati.

Zatim namjestimo front color bijelu, odaberemo okrugli kist sa mekim rubovima, namjestimo mu

opacity na 100% i kliknemo na sredinu ( u ovom slučaju na glavu dječaka). Nakon toga odaberemo

nešto veći kist, namjestimo opacity na 50% i ponovo kliknemo na isto mjesto. To ponovimo još

jednom sa još većim kistom i opacity 25%.

Ako nam se pojavio rub slike, možemo ponovo front color namjestiti na crno i malim kistom prijeći

preko tog mjesta. Postati će opet nevidljivo. (slika 14)

Istu tehniku možemo koristiti umjesto početničkog izrezivanja slike pomoću lasso tool-a. Jednom

izrezana slika ostaje takva, dok masku uvijek možemo ukloniti ili prepraviti i imamo mogućnost

mekih rubova. Važno je zapamtiti da pri korištenju maske crna boja čini layer nevidljivim, a bijela

vidljivim. Na taj način je ” izrezan” i ovaj uskršnji zeko (slika 15)
