I load all my micrographs into The Gimp, first cropping and then using the Brightness/Contrast control until they look better, then sometimes adjust the color levels, often with curves or auto levels or both. Unsharp mask usually makes them look better as well.

I played around with the exposure of the pleurocystidia micro-shots, in Observation (58500), to lighten them up. I liked the outcome.

I can probably go back and edit some of my other micro-shots (as these tend to be darker) to make them a little brighter. And for the blurry ones, I can play around with the sharpness to give a little more clarity. But it might be a little bit before I can get around to doing this. I’ve been real busy lately.

I admit that my observations do have some blurry/not-so-great photos, but I’ll work on my photography and hopefully my future posts will be up to par.

Thanks for pointing this out. I’ll keep this in mind before making future posts.

If you have a image editing program even a good free one like Gimp, and a little time you can really improve your image quality to, some times, even better then what you see through the scope with your eyes amazingly.
you can edit the contrast and levels and even sharpen the images a bit to really bring out the shapes more clearly and lighten up some of the darker pictures.

Thanks….
