Question
I am using photoshop to edit an image collected through microscopy, the
image that i am working on was collected as individual scans and tiled
together as a montage. However during the scanning of each tile it appears
that there is a gradient which causes my final image to look like a checkered
pattern. I was wondering how i can remove this from my images. I do have
the original scans that i can montage myself, but how can i remove the
gradient in each scan.

Answer
Hi Bryan,

When stitching images together it best to have a consistent background. Once the images are taken though, it's hard to compensate for uneven lighting.
Photoshop's stitch tool will eliminate some when it stitches the image or you could use the healing tool to blend together large seams with like color and texture.

Hope this helps,
