Over expose on 40D


burger

Recommended Posts

Please help. I took some bird shots yesterday. The birds was in a Magnolia

grove and it was a bit dark. I used a 40D and a 100-400L lens at 400mm. IS was

on, ISO was set to 500, F-stop was f5.6 and speed was 1/60. Some of the shots

was shot at ISO 600 and others that sat on top of the trees was shot at ISO 100.

All of my photos (I took about 60 shots) came out totally over exposed - look at

the example. My cameras exposure was set at 0. It somtimes happens with my

24-105L lens as well. I have two 40D bodies and it seems that it is just the one

doing it. Any advice.<div>00Pqbk-49621584.jpg.00f0cd5f8171f778df521504447dc263.jpg</div>

The result is normal - this is how the camera works. The camera meter will always calculate an exposure such that the picture is average gray - neither too bright nor too dark. This is how your picture came out. The camera has no way of knowing if the scene you shoot should be darker of brighter - it just calculates an average based on that scene. If you want your picture to be darker than average then you should use negative exposure compensation.

Seconding Daniel D - this just needs a small amount of PP to be fixed - in Camera Raw some recovery, some contrast, and some vibrance would prolly do the trick, plus some capture sharpening.

 

If you want, I'll give it a whirl this evening after work.

As it's just the one body 'doing it', have you checked every single setting in both of them, to make sure they are exactly the same?

 

I've found in the past that disparities between bodies are often corrected by resetting both cameras by clearing all camera settings and then manually inputting whatever setting I want.

 

Clear all camera settings is in one of the menus in the 40D.

Chris Newell beat me to it...You can even remove both batteries for a while to be sure.

 

Also the image you post did not look over exposed to me. Maybe a little bright, but that seems to be from the meter try to get the dark colors to middle gray.

 

If you can try both cameras at the same subject and same light and then compare. That should give you an idea.

Yes, it's a little overexposed. That is for jpeg. If you had shot RAW, it would be within the

normal range and easily adjusted in your RAW converter. This just shows why it's a good

idea to shoot RAW. If you shoot jpeg only, it's a good idea to review the images and adjust

exposure accordingly for the next one, or bracket your exposures.

 

There is very little exposure latitude when shooting jpeg and if you want a perfect exposure

you'll usually have to work for it.
