    Hi Guys

    Here is a original pic I took from my tank with my cellphone.

    [​IMG]

    Here is the exact same pic with some color and sharpness editing done. Took about 5 min.I have always wondered how many tampering there is with photos you see of this amazing tanks in Aquarium books.

    Nice - thats a very healthy java fern you have there :)

    I have found that sharpening a photo works ok when you resize it to a smaller size, but for larger pictures it comes out too grainy to be of any use.

    What tools are you using to edit the photo?

    I seriously doubt there is a single professional photo out there that has not been sharpened.

    Photoshop does sharpening *very* well. The unsharp mask gives you a lot of control and with a bit of practice you can make a photo look a whole lot better. The idea being, of course, to make the photo look more like the original not better than the original :)

    If your editing tool has an unsharp mask try using that instead of a simple sharpen wizard. Perhaps one of the free editors has an unsharp mask? (I've not looked at the new alpha of Paint.NET or at GIMP lately).

    Obviously starting with a good image will give you the best results. Try keeping your camera/phone as still as possible. Lean it against something sturdy (a table or heavy chair), this will make a huge difference to the image quality (a tripod & cable is the ideal solution, although a little overkill for a cell phone...)

    That looks better. The 1st image you posted was a little over sharpened. Problem is the sharpening is making the JPEG artefacts more visible...

    Remember to save JPEG files as infrequently as possible. Every time you open them up and save them again you loose some quality (lossless compresioin). Also perform the sharpening as the very last step in the image editing process. I.e. resize, levels etc first then sharpen last.

    Something else you could try is to do something about the highlights at the top of the image. I.e. make the top a little darker (in photoshop you would use curves or the shadows & highlights filter).

    :-[

    Make that "lose" not "loose" and it is "lossy" not losless compression.


    Sorry. My canister filter broke last night and I'm away this weekend I blame the poor spelling and misinformation on the resulting stress :)

    Unsharp mask filter is what all discerning image editing people use, because it is so configurable. You have several different controls to play with to ensure the sharpening works as you want it to. Pretty much all editors have some implementation of it.

    Pretty much all images you ever see have some manipulation done to them. Removing dust from slides, changing the overall tonality of the image so that the printed result looks OK, changing the colour balance to adjust to differences in the output and allsorts. You can also seriously change the overall "look" of a picture.

    I generally always adjust the brightness/gamma of an image (photoshop's shadow/highlight filter is my new favourite toy); often increase the saturation a little, and pretty much always run an unsharp mask, usually 50% 2px, as the last step before saving.

    Not true, there are some amazing lenses out there that provide tack-sharp images :)
