Počeo sam raditi sa Adobe Photoshopom i učim malo po malo. Jedna alatka mi je jako interesantna ali mi nisu jasne neki detalji.
Radi se o alatki magnetic lasso tool, može li ko da objasni šta mu znače:
-feather(pix)
-lasso width(px)
-requency
-edge contrast
-anti-aliased

-feather(pix) - koliko meksi hoces da bude prijelaz izmedju selekcije i ostalog prostora.
Znaci ako je feather recimo 0px imat ces cisti rez. ako je 15px imati ces lagani prijelaz ili "fade-out".
Za probu - otvori neki jpg napravi selekciju sa Rectangular Marquee tool-om. odi na Select - Rafine Edge.
Kad se otovri prozor, izaberi prikaz slike na bijeloj podloz. Vidjet ces jednu od opcija Feather. Zumiraj rub selekcije i pomici slider i vidjeti ces kaj se dogadja.

-lasso width(px) - udaljenost od alata do selekcije.
Recimo imas dokument koji ima bijelu pozadinu i crni kvadrat.
Ako stavis width na 1 i zelis zaokruziti kvadrat morati ces doci s alatom skroz do
ruba kvadrata. Ako stavis na 150px, toliko mozes biti udaljen od kvadrata s alatom,
a selekcija ce se zaljepiti za njega

-frequency - koliko cesto hoces da stavlja "selection point". Male kvadratice na selekciji.

-edge contrast - ako recimo imas opet onaj dokument bijela pozadina i crni kvadrat
(ili blo koje boje ) contrast ti moze biti na minimumu. Ako imas neku fotku prirode
contrast ces podesavati ovisno o selekciji.

- anti-aliased - Pegla ostre rubove u selekciji
