In the last post I showed you what happens when you use Lightroom to stitch two vertical orientation scans into one horizontal orientation one. Lightroom amps up the contrast and or the sharpening. In an attempt to get around that, I stitched the stacked images from the last post using PTGui 11.7 and 12.8. The… [Read More]

Yesterday, I reported on using pixel shift on the GFX 100S to scan negatives. There is another way to increase resolution, and that’s stitching. I turned the camera into portrait orientation and performed a two-view set of captures for stitching. This meant that the 4 inch dimension of the negative was imaged to about 40… [Read More]
