Exposure studio quandry

12 years 4 months ago #175733 by PNMBritt
Okay,
Typically I balance my exposure off the histogram from a grey card image. I run my main about a 1/2 stop to the right and my fill about a 1/2 stop left. I bump everything up a little if I am shooting to the right and I usually do because it typically works better for me in RAW. All this is done from the camera back. (Scarey I know). What I am wanting to do is balance this using a captured grey card, from Gimp software. In this scenario, I am adjusting exposure by lighting placement and keeping my f constant. Then using this grey card image as a color balance. Basically what I am doing in the camera moved to the computer, but untethered.

Application would be school, sports, ect. I do a lot of this type of work. Just looking to streamline a little.

Okay,
I have doing some homework and now it is time for the test. After this evenings photo=session, I am going to shoot a grey card and a quickly done portrait on a card. Once home, I am going to take a look at the histogram on the laptop and see if I can gauge off of that, then batch white balance. If this works and I can do this with two - three bodies at a time, this may be a good thing. We will see.

You have me puzzled, as I am not clear on what you are trying to achieve, your descriptions of what you are doing are not clear enough to be understood and answered.
Also what it is you are doing seems to be working as the photo shown is very good, in that case dont fix what isnt broken !!! :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup:

Let me try this again. Currently, I am shooting a target / grey card and using the camera histogram to balance my lighting to the way that I like it. I use the same captured image of the grey card to batch white balance control in the computer. I have done this a million times and actually I am getting quite fast at it. Typically speaking, I set my camera for the effect that I want and very the lights power / distance to get the exposure that I am looking for. I know my exposure is correct and my lighting ratio is where I want it. I would just like to have a fail safe to view the histogram in Gimp before I begin my process. Turns out, it can be done! Now the same image that I use to check my lighting is the same image that I use to batch WB. Sort of like what they do with tethered systems only without manipulating the camera settings, so there is no real need to be tethered. At least I don't think so. I am still experimenting with this.
