Bracketing.....

[boccers_2000]

Hi Guys, couple of quick queries.

I often bracket exposuires (ie take one pic at the deemed correct exposure, one then a +1 and a -1 exposure). I have a Canon 500 D and find the easiest way to do this is set up the camera, go to exposure, adjust to select the 3 exposure requirements, go into remote control and simply hit the control and it automatically takes the 3 pictures in quick succession.

Question 1 - Is there any way of doing this for 5 or more bracketed exposures without having to go in and maunally adjust? I mean if I am shooting a landscape then it can sometimes be important for the pictures to be taken in quick succession to avoid ghosting etc. If so, how would I do that on a 500D?

Question 2 - I have been tinkering with HDR and I understand why you feed 3 images in (ie it amalgamates the best exposures on each part of ach picture to create 1 all round good exposure etc). Why would you use 5 or more? to allow the program to do this more subtely?

Thanks for all your help

You can do it with other cameras but not with yours.

Yes.

Q1 - as Chris said.

Q2 - All HDR is stretching the dynamic range from black to white. A lot of people confuse that with tone mapping and whacked out colour stuff. Think of it this way, your camera can probably handle around 5 stops of light in one frame. You are shooting a sunset, with long shadows, and very bright sky. The dynamic range there is probably like 10, possibly more. it's not how many brackets you do, but how much of the range you want to cover. There are a lot of creative choice to be had. You can also choose by how much you want to bracket. You can also stick it into manual exposure mode, and manually adjust. So long as it's on a solid tripod, your composition won't change, neither.

If you shoot RAW you can go +2 to -2 from the one frame, so start at +4 and -4 and you could cover a huge range with two shots.
