What colors do you use for filling the background so as to see if some kind of border is visible?
May I use
Red RGB =255 0 0
Green RGB =51 153 0
instead of dark grey?
Must I increase gradually the transparency on the border to soften it or just cut hard?
I use different colours sometimes to look at the transparency of a layer in detail. Obviously black and white can be checked against, but also obnoxious and super bright colours like hot pink can help reveal subtle details in edge transparency. Also a good technique is to use a levels adjustment layer and play around with it to increase contrast between layers / objects and therefore sometimes see certain artifacts revealed. As far as softening edges of an object, there are like everything else in photoshop about a million ways to achieve this. Blurring, Feathering, manual painting etc…
Thanks a lot! That info was very useful to me.
So, you give me to understand that border doesn’t have to be hard and transparency doesn’t has to be like 0/1 (in/out of the figure), therefore border must fade away gradually increasing its transparency.
Your work is amazing! Like an Art Gallery! Very fine work!
thanks, glad you like my work.
Yes you can have transparency other than 0/1. Obviously if you save your work in a format that supports it like PSD of course. TGA and PNG are common formats which support 8-bit transparency.
I’m a little confused exactly what your original question was referring to. Are you asking how to extract and isolate an object from a photo? or create a vector clipping mask?
