interior photography

Also if you have photoshop, shoot your images a bit wider than what you need in the shot then when you crop in PS check the "perspective" box that appears at the top when you select the crop tool, then use the corners to pull your edges back to parallel with the sides of the frame. I have found that leaving a little bit of distortion actually looks more natural than none at all.

Oh thanks for your help Photosguy,

I have been running some tests to try to learn what you have explained.

In a small room I have realised that f11 seems to be better than f4.5 or f 28. I think my room is too small for f28 to be as sharp as f11 even at the furthest corner. I feel I can understand DOF a bit better now - thanks!!

In image 1 what should I have focused on?

It in the "DOF for Architecture" link I gave you?

A tape measure works, too. Measure the height of the lens above the floor. Measure the same height on the opposite wall above the floor, & put a piece of tape there. Aim the center focus point at the tape.
(Don't forget to remove it!)

does anybody know if there is a way to hack the firmware to allow more than 3 bracketed images and make the spacings further apart. Seems to me a very false barrier imposed by canon that could be worked around....

You don't have to use automatic exposure bracketing. Just put it in Manual and you can choose whatever exposure you require.

Real simple.

1. Shoot in RAW mode so you can fix the white balance. The camera's Auto white balance mode will often get it wrong with incandescent lighting.

2. Use a tripod, f/8 or so, ISO 100, and a slow shutter speed.

3. Keep the surface of the lens as perpendicular as you can. If the camera/lens are positioned at an angle, you'll get persepctive distortion which will make vertical objects appear bent and crooked.

4. Don't forget to add some sharpening in the software!

Thanks for all the tips folks!!

I have tried to take on board all the comments and I even have a copy of Photomatix so Im having fun with HDR now. Noise is a pain though....
