How to extract edges?

[Mastropiero]

Hi everyone, first post here, glad to be here.

 

I have been browsing a lot through the FAQ and also searched extensively but I haven't manage to find quite what I am looking for, I apologize in advance if I missed something.

 

I am working on a small project and I would like to use the image of a bengal tiger, but not the whole image, just the edges. I'd take this image, for instance:

 

 

Let's say I'd only use the portrait of the tiger but I am not interested in anything but the edges. Kind of what I see when I muck about with the High Pass filter. I'd like to take "those edges" sans the gray background and place them on top of something else. The latter part is not important, I'd find the way to do it, but I haven't been able to isolate or to extract just the outline of the stripes/spots/eyes etc.... 

 

I am sorry if I am not making myself very clear, hope I do, but English is not my mother tongue and also photo editing is far from being my area of expertise so I am probably using the wrong terms, so I apologize.

 

 

Many thanks for your help.

Hi,

not sure what you really want to get as an outline view here, but you can try out some filter on a layer duplicate, like emboss, relief or a tonality step down. Further you would probably then need to get a selection of only certain areas (without the background), so you can copy/take over only the selection of the interested in parts over to another image.

I would start with Filters > Find Edges. (Having duplicated your background first.)

Or is it  some kind of sketch effect you're looking for ?

Then R C-R provided a macro to convert your image into a pencil effect

Hi everyone, thanks for your answers, this is something that could work, I will try both methods anyway and see what gets me closer to what I'd like.
