quick query...

quick question here guys...

hen I had my panasonic fz7 - towards the end of it's ownership I began to experience some shots being over blown (i.e. very bright) on a sunny day etc - this included the various settings I used...

now it seems that the same is now happening with my canon 400D - but mainly on the Av setting - but sometimes when I revert to the Tv (shutter speed of 4000/1) the image is ok... is it just down to circumstances (i.e. sky being too bright) or an issue with the shutter..?

cheers

Re: quick query...

Can you show us an example picture? Ideally with the Exif information so we can see how you had the camera setup.

Re: quick query...

From what I can see 0171 is slightly under-exposed (hence the saturated colours) and 0170 is over-exposed resulting in loss of detail in the sky. If the only difference in the Exif is the aperture then that would make sense.

Basically the camera has exposed one frame for the sky (leaving the branches under-exposed) and the other frame for the branches (leaving the sky over-exposed). I'm not sure that is indicative of a fault on the camera, it's probably just one of those situations where the metering software had a bit of trouble deciding what to expose for.

Re: quick query...

Looks like spot meter is set and it's exposing for tree or sky - be worth changing it to average and then if there are particularly bright/dark areas, using Exposure Compensation (or manual)
