I'll have to reload it again.
I have to put in on a server and then put it here.
I use several programs for photo editing(Canon, Nikon, Pentax etc).
I use the full one if possible.
I also try and use the largest MP's as I can to start with.
Photoshop may be similar.
There are other programs, but they all have some basic similar features.
I tend to use the sharpness/blur feature and increase sharpness a fair amount.
Play around with this, it can make the pic too grainy if you go too far.
Basically I'll use the brightness control, contrast and Gamma.
I do not raise the B and C much, and reduce the gamma.
This yields a clearer more true to life clarity.
Maybe some Cropping, I try and think of that while I'm taking the picture.
Resize image etc.
If you go under "colors", "hue" can help a lot. I do not use it much though if at all.
Also you computer screen, the camera's color capture etc also play large roles in the preception.
It's important to note:
Pictures are not reality, they are "art"
There is a lot that can be manipulated post editing, just like with news and video's.
The best advice I can really give however, is to simply try playing with these features and see what you like. You will learn a lot by doing and playing around with these features.
It will also help to let us know what type of camera, MP's, flash, editing program you have.
That's a beautiful layout. I like the simplicity of the layout and the spareness of your planting. Very subtly balanced, the dark green crypt mirrors the form of the helferi (?), but also provides a contrast of texture and value. Less is definately more here.
What is the plant against the right side of the tank? Hygro compact?
As far as the photograph goes, it's good. The color balance is a little off, I'd warm it up a little by shifting it toward the yellow/red spectrum. A "white balance" or "color balance" in an image editing program would do the trick. Also tweak the black level and gamma with a "Levels" tool. If you don't have something you like, I'd recommend Adobe Photoshop Elements.
