After all the testing done so far, I decided to play with some image manipulation. All images get shrunk down to 48 pixels tall from whatever size they originally are. This poses a problem with sharpness. So I spent the evening doing some testing with a little bit of re-sharpening of the image. I say a little bit because any tiny change will be too much. Ultimately I settled for some values that were just enough to get some details back.
The next step was lowering the image gamma. With the LEDs being so bright, just about anything I put up was getting washed out. Normally on a computer you’d set a gamma value of 1.2. Here, I had to lower that to 0.4. Big swing. But, the results are much better:
