While I was looking for the slit-scan sunset of yesterday’s and the day before’s post, I found one that I’d never printed: Here’s what it took to make it work: No Matlab work required. Also, note that I didn’t create that place in the center of the image where the sun brightened up.

I managed to restore the fog to the lower left corner of the sunset image in the last post. When I edited the first version, I used a Photoshop plug-in called Contrast Master to give the clouds some sock and pull up the details in the dark areas. That plug-in in no longer installed on… [Read More]

I’m working on material for a presentation this weekend — more on that in a future post — and I decided to print this slit-scan sunset image: But when I looked at it closely, I saw some artifacts near the horizon: I figured the Matlab one-dimensional averaging code that I created for the succulents pictures… [Read More]

My silence over the last few days has not been because I’m on vacation. On the contrary, I’ve been really busy figuring out how to process the succulent slit-scan images. Doing it all in Matlab offers the most flexibility, but there’s not much interactivity. I create a set of parameters, process a bunch of images… [Read More]

In the last couple of posts, I talked about how to smooth slit-scan photographs in the time direction. For the time being, I consider that a solved problem, at least for the succulents images. These images require a lot of sharpening, because the subject has a lot of low-contrast areas there’s a lot of diffraction,… [Read More]
