Hi Ken,

On a Mac it's Command + or Command - to zoom in or out. For whatever reason it
doesn't work with the GIMP help browser. But now that I have the GIMP help as a
PDF I'm all set.

Great software. I just need to learn its secrets.

Thank you,

PJW

[Gimp-user] ***UNCHECKED*** Gimp help browser on high rez monitor

2020-03-25 Thread PeterJWhite
My monitor is 3840 x 2160 on a Mac. The help browser offers great help, but it's
difficult to read as the font is so small on my monitor. I can't find a way to
increase the font size other than changing the screen resolution. Is there a way
to do that within Gimp?

Thank you

PJW

Thanks to you both. It's working.

[Gimp-user] change background in photo to grey scale

2020-02-05 Thread PeterJWhite
I'm brand new to GIMP. I photographed a bronze sculpture on an off-white paper
background in natural light. The shadow areas of the background range from white
to a peach color. I'd like to change the background to greyscale and then adjust
it separately from the sculpture. I've made a quick mask but now can't figure
out how to make the background a separate layer from the sculpture, so that I
can color correct the two layers independently. The sculptor wants to keep the
shadows in the background.
