View Full Version : Overexposed images - can something be done in post?
Rati Oneli August 29th, 2006, 02:17 PM Hi, first off I apologize if this is a wrong thread...
Hi, I shot some of the scenes and they came out overexposed. In this particular scene I also used the filter option that HD100 has.
Links here are for the overexposed shots:

Links here are for the ones that works for me. What can be done? if nothing than at least I o won't think about it smile.gif)

Thanks a lot guys
Justine Haupt August 29th, 2006, 08:42 PM To me, the first set doesn't appear overexposed at all. I'm curious to see what others think.
Lisa Shofner August 29th, 2006, 09:37 PM I have to agree with Justin. I don't think they look overexposed either.
Of course, if You feel they are overexposed then they are (it's your picture). If they are slightly overexposed (to you) then I think you can use a filter in your editing software to correct it, as long as the details are there to bring them out then you can.
I know you could adjust each frame in Photoshop to bring down the exposure level. Basically that would just darken everything, i believe.

2- Try lowering the gamma or "midtones". This feature is available in practically all NLE's color correctors. You can try this in conjunction with lowering the white point a little.

Thank you guys for such a quick response.
Glenn, for editing I will use FCP 5. But, if you mean for color correction, grading, I won't do it myself - I'd like to take it to a professional.
One other thing: I forgot to mention that these both scenes are from one episode and happen one and the same day in the film. That is the reason I am so worried, becasue I'd like to intercut them somehow. I know in the very end I might have an option to take the second row images (which have more contrast) and make them lighter ?
Rati Oneli August 30th, 2006, 01:42 PM In a way I am relieved that they don't look overexposed to you. Probably they look over exposed to me because the second row of images has the contrast ratio and look I was going for...
The main problem is that I will have to intercut the different shots with each other, since they are supposed to represent one and a same episode during one and the same day/party
Glenn Chan August 31st, 2006, 08:49 AM If you are really concerned, you can rough up the color correction in FCP to see if the shots will intercut well. Use the 3-way CC and move the middle and right-most sliders under the color wheels around. The middle controls the Y' gamma, the rightmost slider controls Y' white point.
Whoever is doing the color correction should be able to fix things like this to make shots match. This will work unless your shots are way off in terms of lighting or technical reasons (i.e. overexposed). Your shots look fine to me.
Chris Chang August 31st, 2006, 10:07 AM You can verify if it's overexposed by looking at the luma waveform, and if there's a thick band at the top... then it's prob a little overexposed. if there's a strong thin line at the top... then you're screwed cuz you lost a lot of data and no amount of color correction will bring it back.
for your application, i'd probably go strait to the CURVES adjustment rather than playing with gamma.
Don Donatello August 31st, 2006, 11:48 AM IMO gamma will just make it look flatter ...
IMO you need to work with something like color curves and lower the black level .. then raise the mid tones slightly and raise the whites ...
the bottom is the original - other 2 are different
Rati Oneli August 31st, 2006, 12:52 PM Hi friends,
I appreciate your invaluable advice and input enormously. I feel like I've seen the light at the end of the tunnel. There was no way for me to go back to the location and shoot the scenes again. I feel enormous relief that something is possible now.
I am copying down all the replies and will take it all to the colorist when we go to post.
Thank again.
Rati
P.S. If anyone else has a different opinion I am ready to listen.
