Anyone know of any free software that will allow me to combine two pictures - say a hand and a painting - so it looks like the hand is pushing from behind the painting.

sort of this

Combined with the painting to create this image but with the hand covered in painting

Basically I am trying to digitally create an image so I can then replicate it on the actually canvas just using shading to imply the hand and ball are there

I think the thing you need to google is shader map or bump map generator. Normally these need a grey scale image of the 'bump' (the hand) with different shades of grey implying differnt heights.

I think that does exactly what you want.

I just made this (click on the diffuse and load the painting). Has instructions on how to use a photo to create a bump map.

The problem with what you are trying to do*... Is shading along won't work.

* I think you are trying to make the painting stand up as it covers the hand? Thus woukd require distorting the painting to show height.

It will just look like a flat painting with shading of a hand over the top. It won't look like a hand coming out of the page.

It can work well and saw some on a Facebook art group but I can't find them now. It is a bit like the 'weave' in this one : https://www.nicksartstuff.com/product-page/woven-canvas

I found a good example, not my work.

Something that will help me get that effect?

Texture overlay is what you want. However, with that example, those two images interact.

this is free - I don't do huge amounts of image stuff (and it's surprising what you can do with windows paint ๐Ÿ™‚ ) but this has more features than I use - just don't tell someone you're downloading gimp software

(GNU Image Manipulation Program).....

krita is a pretty good free option as well.
not sure about specifically what it's like doing what the OP is looking at, as I'm a fully paid up adobe zombie!

Gave up on trying to use software as I would have top learnb that as well as how to paint.

Clearly I now need to learn to paint. I have painted the lowlights in but might need some further work.

It is a bowler having just released the cricket ball which is whirling away into the distance. It works best if you squint a bit, shut your eyes and turn around and just imagine the painting ๐Ÿ™‚

More practice required and I think a different background style with more small patterns would help too.
