For 'bang for buck', do you mean you can buy older-model strobes for less than $10? You get a lot of 'bang for buck' if you can pick up an older CS-variant of Photoshop with license.
 
I hear what you are saying. If one got the software for free, the benefits would approach infinite! Maybe the ecomomics aren't the only consideration.The fact is that applying full image color correction to Jpgs is very lossy. The cost to the quality of images is therefore high. The best fix is to ensure good image capture. A strobe really helps ensure the full light spectrum is captured in each image. When it comes to getting the most out of your camera, a strobe must be considered. That's all.
 
I have Windows Live Photo Gallery that came with Windows. You can play with a lot of things like contrast, brightness, adjust the color etc. It's not great but it can help. A strobe is very helpful but you still need to be <5' from the subject to get the real colors. The color red will be pretty much gone in 12 feet of distance. Even using a strobe 5 feet is pushing the envelope of most strobes if you want to have true colors. A manual White balance will help but so will shutter speed, F settings and ISO. I have a DC 800 and have found taking it out of automatic and using manual mode with settings of f stop (set to the highest number on my camera it is 5.3), shutter speed (1/125th sec) and manual setting of the ISO (100 or 200) while using a strobe you have to play with it a little to find out what works best for sure. Take several pictures and change the f stop and shutter speeds. That's the great part of digital, if the pictures aren't any good just delete them and keep the best one. I have also found that while most pictures turn out ok there are only a few that are really good so the more you take the better your chances are of getting a great shot. A strobe will help a lot but won't if you are too far away. To my knowledge the DC1000 does not shoot RAW. I know the DC1200 doesn't and neither does the new DC1400.
 
Although RAW helps a LOT with the blue pics raw material so to speak, you can fix up your jpegs as well quite a lot with programs like photoshop, photoshop lightroom or apple apperture.
Yes, but nowhere NEAR as well as you can if you have the RAW file, simply because the jpeg is already compressed and has lost a lot of data..
 
I normally use Photoshop or the free alternative Gimp to correct my underwater pictures. But the best approach apart from shooting in RAW (what is not possible with your camera) or adding strobes (needs money) is to use custom white balance for your next shoots. Check you camera manual how to do that and give it a try during your next dive. You probably still need photo editing software to correct but at least you have more red in your pictures to start with. Check an article on my website for tips to improve your underwater shoots.
