1 About this approach
In this approach we use photoshop to align images and make image brightness, contrast and other adjustments. These instructions are written for photoshop CS6, but they should be applicable to other recent versions of Photoshop.
This approach has these advantages over aligning images in adobe illustrator or other vector package:
- Opportunity to automatically align images
- Ability to make image brightness, contrast and other adjustments live (and reversibly)
- Ability to make granular image adjustments (i.e. at the edges of aligned images to make them match better).
This article has been specifically written for using the macro-photography setup in the Graphics Lab in the geology department and Adobe Photoshop CS5. Concepts are applicable to other equipment and versions of Photoshop.
I have made a new post with instructions using Zerene stacker to stack the images rather than photoshop because it is faster, easier and produces better results in all cases that I have seen. For example Zerene Stacker took 72s to stack 11 images and photoshop took 125s, the difference in stacking speed is even more pronounced when more images are used.
