Easiest way is to turn down the resolution on your camera before you take the picture. Notice how grainy they look up close, too - "megapixels fuck yeah!" doesn't make for better pictures. It's probably a good idea just for the sake of quality to turn it down a bit permanently, anyway.
By the way, I eventually gave in and looked at them (right click -> Open Image in New Tab -> zoom to heart's content) and it looks nice. Love the look of the PCB with the clear mask. I have a generator with similar specs and it's a total piece of shit. The PCB is covered in bodge resistors and bodge capacitors, and the original design is so flawed that it doesn't work at all with the bodges removed. Doesn't work very well with them either, though I improved it with a few of my own bodges. (Simpson 422, by the way. Avoid Simpson...) Nice to see one that's well designed.
(I also have an 80's HP digital generator and it is a work of art, too.)
