It looks like I spoke too soon. On 6.7.8, the result is different than on 6.8.9 and 6.9.9. In fact, the image is overall darker, and there’s far less contrast.

Is there anything I can do about that, given that I can’t update IM on the server?

Yes sure, already that – thanks!

This works fine on 6.8.9-1 Q16 x86_64 2014-06-29 as well as 6.9.9-11 Q16 x86_64 2017-09-22. Yet, the server is running 6.7.8-9 2016-06-16 Q16, on which I have to do -colorspace gray -colorspace rgb.

Thanks again both!

Re: Emulate Photoshop/Gimp blend mode “Overlay”

Thanks both for the helpful insights. What I noticed is that -evaluate set 50% doesn’t seem to make any difference: convert fMcAbNx.jpg -channel A -evaluate set 50% +channel ( +clone -fill #ff9090 -colorize 100 -alpha off ) +swap -compose SoftLight -composite out.png convert fMcAbNx.jpg -channel A -...

Emulate Photoshop/Gimp blend mode “Overlay”

Hi, I’m trying to replicate Photoshop’s or Gimp’s “Overlay” blend mode in IM. Here’s what I’m doing in Gimp: 1) Open any image. 2) Make it grayscale. 3) Set the layer’s blend mode to Overlay. 4) Set the layer’s transparency to 50%. 5) Set the foreground color to light red #ff9090. 6) Create a new la...
