multiply-blending-mode-to-png.md

1. copy your image (Ctrl+A and Ctrl+C)
2. make a new document-sized pure-black layer behind it
3. group the black layer and yor image together
4. add mask to the group
5. enter mask edit mode (alt+click on the mask icon/thumbnail)
6. paste your image in the mask (b/w) and then invert it.
7. save it as a 24-bit transparent PNG

Hi All.

I am trying to follow this, but perhaps I am missing a trick as everyone here seems to have this working perfectly.

I have an image on a white background that was taken in a photo booth. This has a particularly nice shadow that I would like to retain on a PNG, while removing the white background. Colour replace is not working as effectively as a multiply blending option, so this guide seems perfect.

However, I copy the images with the blended layer and the original, to a new document with a black background, then perform step 2 to 5, but upon ALT clicking the mask I cannot seem to past the image in the mask b/w and then invert. Nothing happens when I paste.

Can anyone suggest what I might be missing?

Here is a file that I am trying to do this to, but I am looking for the method, not just the result. I am so sorry if I come off as a little slow here.

@ALL OMG I only today noticed people are using this :) I need to turn on my notifications.

@lewisisonfire I think this is not for you. What you're trying to accomplish is a bit different. This instructions are for a photoshop file with a complex transparent group of objects that you need to export as a single usable png. What you are looking for is cutting out objects with their shadows from a white background. It will take quite a lot of manual work unfortunately. I would do something similar to this YT video https://www.youtube.com/watch?v=zakUq2BTQDQ

@magicznleszek, I ended up using this and a similar method using an inverted version and pasting into a solid black later mask. Worked out perfectly, so thank you so much for taking the time to respond.

Wow, I just needed to do this and this was really useful, thanks!

Wohoo! Thank you!
