One of my many frustrations with reef keeping is photography and comparing coral via photos online. There are those with LEDS, T5, MH lighting and all combinations of the above and they lead to different "looks" to a tank. Then complicating that issue is photography. Some use dslr's and others use iPhones. Some photos are then either photo corrected or photoshopped. Most people strive for accuracy, others, well they have different motivations so to speak.

A pretty picture is a pretty picture. But I am really referring to something else, more about objective comparisons of coral coloration.

This debate is interesting because there are proponents that view an"uncorrected" photo shot under whatever native coral lighting the photographer's tank is blessed with, taken with any kind of camera is both accurate and honest. Others believe that unless a photo is color corrected for "temperature" and "exposure", it is neither an accurate representation nor honest.

I am not referring to enhanced photos that may be utilized for sales, that is not really what I want to talk about at all.

I got started on this thought process because I took a bunch of chalice shots, my favorite part of reefkeepiing is taking pictures, and I was color correcting for temperature and exposure in an attempt to accurately reflect as best as I could of what my chalices look like in my tank under t5s and metal halides. So I have included the before and after, "as shot" vs "temperature and exposure" corrected.

you can do a lot of it on camera without having to toy around in post.. you just need to adjust the color temp to custom, and crank it up as high as your camera goes. :)

My camera goes to 10k only, and I have tried using custom white balance setting in camera and still not effective. It seems easier and more accurate to shoot in raw and then correct temp and exposure. Am i missing something, I desperately could use a reef tank photo course

I started a write up on this, but haven't really gotten around to finishing up the "intermediate" and "advanced" versions of it.

the problem is that even when you take a photo in raw, the nature of the heavy actinic colors in our tanks will blow out the color curve with so much blue saturation, which you can clearly see in the histograph.

to really be able to white balance it, you have to crank the custom white balance to 10k, and then use a gray card, and manually bump up the temp even more in post.

by just cranking it to 10k on the camera though, the photos won't be nearly as blue as the cell phone pics.. :)

What is the advantage of setting the camera's white balance to 10 k and then color correcting (temperature ) in Photoshop vs not adjusting custom white balance and complete color correction (temperature) totally in Photoshop

it's additive, rather than absolute.

not sure if that makes sense, but by setting the camera photo to 10k first, it'll come into photoshop/lightroom/etc as "neutral", and you'll be able to crank up the color temp even more, resulting in something more like 28k, which is more than you would be able to do in post alone.
