Originally posted by SMcGuire45 Sometimes, not all the time though, when I take the photos one of three will be shifted slightly. I thought it might be me when pressing the shutter button, but it also happens when I use a remote shutter release. Sometimes I like to blend all three images together, but it's impossible when one if the images shifts.
If you are shooting hand-held, the shift is inevitable and almost unavoidable. 3 Shots are fired in quick succession and sometimes when the shutterspeeds are high enough, they're fired off so quickly that the shots end up lining up perfectly (depending on how stable your grip on the camera is). More often than not, the shutterspeeds are short enough to produce individually sharp images but the time between the shutter opening on the first shot and closing on the last simply is too long for you to hold the camera perfectly steady over that time.
If you are shooting from a tripod with a remote release, the only way this could happen is if you did not switch off SR. The anti-shake system will continue to move the sensor around slightly causing loss of sharpness/detail but also the described lack of alignment. Only other source of misalignment could be thing moving in the image like swaying branches, blowing leaves, birds and people (the latter 2 not necessarily in that order).
My advice:
1. Always switch SR off when shooting from a tripod (whether multishot or not)
2. If you forget (1), try using the 2-second timer setting as it will switch off SR automatically
3. If you are having issues with handheld brackets, use automatic alignment software as found in many HDR programs (I use align_image_stack but anything will work)
4. I'm purely open-source on Linux but I cannot believe Photoshop (or its competitors) on Windows or OSX do not have scripts (or actions I believe they're called) to automatically align and blend images. Sadly I can't point you to them because of my somewhat myopic focus on Linux - my apologies for that.
