When writing at Dawne Design about my newest window Project 27–Squared Rainbow Concept, my Photoshop drawings were showing up funny — so I tried a test here. Over there, with a light blue background, the .PNG files appeared like this:
The problem was when I put them in a slide show — with a black background:
Sure enough — the same thing happens here with the black. Whoa, sure shows my lousy painting job, too.
Of course! When designing windows, I save Photoshop drawings in the usually smaller file size format of .png — it keeps the ‘invisible’ background which displays stained glass truer to reality.
Otherwise, if saved in a .jpg [JPEG] format, my invisible background is always rendered as white. This creates a couple of problems with my drawings — there’s no difference between clear vs. white glass, plus, semi-opaque & clear coloured glass are distorted by the white behind them.
In this case, I changed the files to .jpg & gave them a very light blue background to represent the sky. And I was shamed into during a better paint job to represent the colours. 😆
