Image Playback Accuracy on Digital Rebel

[Agaric]

Just wondering in anyone else out there is having the same problem as I have with the image playback on the digital rebel. When I shoot with a studio Light setup and Manual mode on the camera, the camera seems to compensate for underexposure when viewing the image on the camers LCD. It seems to compensate for up to about 4 stops underexposure. The image looks like I want it to but when d/l to computer it is way underexposed. I am relying on the histogram now but it would be nice if the lcd on the back showed an accuate exposure. ( I have adjusted the screen brightness too- no help there either. )
Any thoughts or comments would be appreciated.

That is correct, You cannot trust the lcd for correct exposure. One thing You can do is to turn the lcd brigthness to the lowest. It won't be enough but it will be a bit closer to the actual exposure.

Don't use the image you see on the LCD to judge the exposure, because it's not accurate. How bright the image on the LCD looks is also very dependent on the ambient lighting - if you're in a studio with dim light, the image will look way too bright, and if you're outdoor in sunny weather, it may look dim.

You should use the histogram to judge the exposure. Here is a tutorial on reading the histogram: Understanding Histograms (http://www.luminous-landscape.com/tutorials/understanding-series/understanding-histograms.shtml)

Not only can you change the brightness of the screen but the brightness of an LCD will change depending on the viewing angle. You may be compensating for the underexposure but holding the camera so that it looks good without even realizing it.

Thanks for the link! That helps me out BIG TIME. :D

How do I view the histogram on my Dreb?

- Dang it...I should pay attention to my own threads. :)

Here's a trick to use when you are trying to get a better instinct about exposure, brightness, and tones.

Get your favorite shot all lined up through the viewfinder. Study it hard. Now, before the shot, try to scribble out what you think the histogram ought to look like. Now shoot it, and then compare your prediction to what actually shows on the histogram.

Keep practicing with all sorts of scenes until you can predict better and better. Don't be surprised if one comes along that is completely unpredictable.

Interesting...... I see what you are saying..... at least I think I see :) I am going to have to try that for sure. Thanks for the suggestion.

thank you, I'm hoping this will help me as well. I too am having trouble with underexposed pics on my Rebel. I was puzzeled as to why images looked rather good on lcd, and dark when I d/l'ed to puter.
