I'll like you to help with a comparision.
The first image just had one simple crop and tidy up of edges.
The Second I did color and tone edits on to try to be back to how I suspect the original mosaic looked before weathering and erosion etc .
Is there a difference or not?
Here's the first version.
and now the second with more edits!
What do you think?
Next time I'll be discussing the use of mosaic filters in Gimp and how I edited letter shapes to get forms that would work the best with that filter.
Oh and yes I did tweak both the reds and blues for this using the Color Tool to deepen shadows and strengthen highlights and mid tones I HOPE ???
