    Please, when you are shopping for a grinder, don’t believe anything you hear (except what I tell you…). A blade grinder is probably as good a grinder as you want to afford. Don’t presume that a burr grinder will automatically produce a more consistent grind. Take, for example, my manual burr machine. Compare the grind…

    I will invoke a variety of principals from experiment design methods. The truth is, though, that I’m self-taught in experiment design. It is altogether probable that there are better ways of conducting this experiment which my ignorance has hidden from me. I’m open to suggestions! Quick Review The variables in control are temperature t, extraction…

    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 use RSS to subscribe to my friends’ blogs, and to feeds from certain authors I enjoy. Subscribe, in this case, means that I go one place to see if anything new has appeared on myriad sources. The software or service that assembles all your subscriptions in one place is called an aggregator. I use…

    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…
