I’ve just added a new set of pages in the training section of this website. These tutorial pages cover 3D Geology diagram techniques. The first tutorials for 3D diagrams using a mixture of free and non-free software are live now. I will also make alternate versions of these tutorials that use only free software soon.
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).
I’ve just put a new section on this website with Illustration/Graphics resources. In this section is a page with a USGS AI pack instructions and a download link. The pack contains patterns for geological mapping such as schist, limestone and other things. The instructions make it really easy to use.
I will be adding a USGS Inkscape pack soon with instructions. I will also be adding more Illustration/Graphics resources as time permits.
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.
