    For Christmas I received a box of slides that had belonged to my grandfather. The slides were 35 mm taken between 1955 and 1961, in a mixture of black and white and color. I do not own a slide projector, and some of the film was starting to deteriorate, by yellowing or showing blotches where…

    We found this really neat moth on our porch several days ago. It had already departed. It was in immaculate condition, and seemed the perfect opportunity for some focus stacking effort. As usual I used CombineZM for the processing, and my Nikon D40 with el cheapo Phoenix 100mm f/3.4 macro lens. Combination of about 20…

    I revisited printing with the Canon MX850 this weekend. I printed a 4-image collage on a sheet of 8.5×11 inch Canon Glossy Photo paper. I had the printer settings for optimization and enhancement disabled, since this gave the most accurate printing in previous trials. The results are shown below. Note that my scanner pooped out…

    Photoshop’s Camera Raw tool, for importing RAW camera images, provides a really delightful little slider called “vibrance”. Paint Shop Pro does not. I read one post suggesting that vibrance was effectively increasing saturation on low-saturated areas. I decided this would be worth trying to emulate in Paint Shop Pro with some layer magic. The results…

    I had no interest in printing at home due to early versions of a study that showed home prints would fade, run, and fail to impress in almost no time at all. That study was updated, and the result made it look like home printing might not be a waste of time. Also, I was…

    This little fellow is a hatchling turtle carved from Phytelephas “nut”, which looks a great deal like ivory. Detail I want to capture includes the small spots on the inside of the egg shell (behind the turtle). He’s a trick to photograph because all three of his dimensions are about equal in extent. That means…

    A friend of mine suggested my first two posts were pretty difficult to follow. To address that, this is the first in a series of posts which will ramble on about other interesting digital photography topics in a more accessible way. Feedback is appreciated. There are lots and lots of tutorials on the net, so…

    Edit: 2009/01/30, evening.  After much searching I relocated an incredible site I had encountered before.  Charles Krebs’ work is really, really, incredible.  I was motivated to explore focus stacking after seeing image 29 in gallery 8, which I believe was produced with stacking.  Dig around his page, it is really awesome. — Original — I…

    I noticed that what I included in my post Introducing… does not look the same on my monitor as it does on my friends’ monitors. While I expected some of that, I observed that the effects of interest were not at all visible, particularly the posterization. To solve that, here’s a quick comparison, done by…

    Philosophy of Use This article is rather long.  Please scan ahead to the pictures to see where we are going, then come back and slog through the details. The basic tasks I’ve needed to perform on digital photos since my first digital camera (a Canon G3, may it rest in peace) are: orientation flipping cropping…
