Improving focus when taking panoramic sequence
Nov 27, 2012 20:41:10 #
This is my first post after reading many issues of the Uglyhedgehog, and I have benefited greatly from the responses I have read here.
My questions are centered around improving focus....When capturing an individual image, I use the focus on button (AF-ON) to focus on my Nikon D200. Through experimentation, I found this gives a sharper image.
However, when shooting a sequence for HDR, I cannot use the same method unless I touch or otherwise potentially disturb the camera. So the question is: How can I get the same positive result of the AF-ON button? Also, have other users found they achieve superior sharpness by using the AF-ON feature or some other method? Thanks.

Unless I am misunderstanding your question, after focusing -switch to manual so it does not change betwen shots.

I'm not really understanding this post. Why do you have to push the AF-ON button more than once? Once it is on it stays on until you want to shoot in manual.
I use auto focus all the time, whether HDR or panorama or normal stills, and never touch the button at all.

I switched to back button focus. This disables the half click focus. Just point your cameras focus dot on what you want focused and press the back button, then you are free to pan to your hearts content.
I didn't think I would like the BBF but after 5 minutes I was hooked.

+1 on Goofy Newfie's comment. Turning your glass to or setting your camera to Manual Focus eliminates all chances of focus drift, unless you are using a long lens which the barrel extends when zooming and you are shooting at an angle and the barrel 'creeps'. smaller aperture will provide greater depth of field if shooting landscapes in HDR.

How are you shooting your HDR sequence? Are you using exposure bracketing? Are you using a wireless remote? I'm a bit puzzled about how the focus changes between shots.

Plus you want to set aperture priority so DOF does not change.

Want to thank you for all the responses. There are lots of items to incorporate in a shot. I will work on these points, try them and come back with observations/questions. Thanks again.

I should clairify that I preseumed "switch to manual" meant switch to manual exposure.
If you also switch your lens to manual focus after it focuses (or you manually focus it) that also will freeze your f-stop and thus depth of field.
