I would like to thank you all for contributing to this post. As a newbie on the platform it can be quite daunting to show your inexperience in matters of photography. This post, was not that. I found you all to be helpful as it affirmed my belief that with flash being permitted, I gave more credence in terms of exposure - to the background and its logo for the sponsors - and not exposed for the speakers. Thanks to your sound advice this won't happen again. What I love about photography is the continous learning it requires. Thanks again all for sharing your expertise - Arlington

Ken Katz - thanks for your input. I agree that the subject required more light. Im also sure that the IDX M2 would have been able to handle the dynamic range required. THanks again

Thanks for your comment BeBu Lamar

Paddle Paddle4 thanks very much for this. From the comments made I am now clearer as to where the problem lies. I tried to be too clever by half to get a clean sponsor's logo on the projector screen when shooting wide shots by exposing for the highlights on the screen. I maintained this exposure profile when I came in for close-ups hence the under-exposed subject. I checked the histogram at the time which was fairly balanced. After your comments I can see that there was scope to push the histogram further to the right to better expose for the subject and to react to any highlights from the screen in post. I have learned a couple of valuable lessons through this post. Thanks very much.

Thanks Kmac - I initially thought it was a lens problem, but your contributions with others confirmed it is an exposure problem, Thanks again

Thanks rodeo_joe1, I appreciate your input

Thanks John appreciate your input. In actual fact the stage lighting wasn't bad for an indoor event. I shoot manual and in this image I made an adjustment - iso - 1000/2.8@200mm with my 70-200mm

Thanks very much Kmac, so you are thinking I am getting too much light on the sensor?

I have noticed recently that in post, my images of delegates on stage during conferences lack overall definition and are grainy despite being in focus. The images are backlit from the large conference screen. I shoot with a full-frame Canon with a 70-200mm lens @ 142mm. My settings were iso 800/f2.8/1/200th sec with a balanced histogram showing good overall exposure My other images, candids etc away from the stage were perfect Could it be that there is too much light coming into the sensor from the stage lighting that has contributed to the degradation of the image. Any advice appreciated. Arlington
