  I have been going to my local aquarium a lot recently, it can be a bit trying taking photos there at the moment as you can't get very close to the tanks therefore get external lights in the picture amongst other things. I have managed to edit some so they look ok (I am only practicing my photography there atm so don't expect anything great) but I would like to know how can I edit these please? I would like them not to be too blue but not too green neither and be able to get the colours of the fish looking better. Is this possible or am I pushing my luck? These are just a few of the ones I have from the deep water tanks.
  I use Paint Shop Pro. Thank you
  Hi Sharon. I don't use PSP, but it should have mostly the same tools as most editors.
  Step 1: Adjust your levels to reduce mid range (shadows).
  Step 2: Adjust brightness and contrast to lighten the image a bit.
  Step 3: Adjust the colour range slightly from blue to red.
  Water absorbs red light first, which is why things underwater appear more blue than natural. Be reintroducing that red colour spectrum, you now have a more natural looking image.
  Hi Sharon. I had a go at this one for you in photoshop. It's never easy with glass, water, and reflections. I got a screen shot of settings I used.
  Thank you both so much! Your help is very much appreciated
  @SharonH, Photography in Aquariums is very difficult due to the low light and glass reflections. It is difficult to get a fast enough shutter speed without shooting at F2.8 and very high ISO 1600-3200. Your photos are underexposed (histogram crunched to the left). I would suggest practicing outdoors in better light to get good exposures to practice editing.
  Thank you Mike For some reason my mind can't get to grips with learning about the histogram, just won't sink in for some reason

  One option you have with under exposed shots like this it to embrace the darkness, take your last shot for example. By bringing down the shadows and blacks and raising the highlights and contrast you can make the fish stand out from the darkness. Here is a screenshot of my experimentation as well as the resulting image.
  Here's my attempt on the first one. I use darktable, but in principle, use "shadows and highlights" juggled with exposure and black level to bring out the fish. Further improve that by using a high pass filter to sharpen. Then use "local contrast", then any other sharpening methods you like. Adjust the white balance to something a bit hotter, and that's about it.
