Saving Memory Cards

Q. While making prints at a local store from an SD card, I saw that I had more than 300 pictures on it. Formerly this would have meant 10 slide trays and a lot of expense. Why not keep the pictures on and label the SD card, make prints when I want them, run slide shows on my TV, forget about filling my computer with files that will crash, and save a lot of shelf space? Too good an idea?

A. It depends. While memory cards are quite robust, they can, and do, fail. That’s why, as with any type of electronic storage, we recommend redundant backup. Of course, you could do this with additional memory cards. Hard-drive storage is much easier and faster to search and organize, especially if your organizer is catalog-based, like Adobe Lightroom. The only other issue we’d worry about is loss of those postage-stamp-sized cards.

Crop Now or crop later?

Q. Generally speaking, which would give better results with distant subjects: an 18–200mm zoom at 200mm without cropping, or an 18–55mm zoom at 55mm with cropping afterwards?

A. You’d have to blow up the image from a 55mm lens to16x20 inches to get about the same subject magnification as an 8x10 made from a 200mm lens. It’s technically feasible that, given a very good short lens and not-so-good long, they would provide about equal optical quality under these conditions. But it’s immaterial—the longer lens would still give you a much better image. Why? Given that you’d be enlarging the image from the shorter lens nearly twice as much as that of the longer lens, it would end up with half the dots-per-inch resolution. This would be like an image from a 12MP sensor compared to that of a 3MP sensor. (Halve the dots per inch in an image, and you get 1/4 of the dots overall.) Bottom line: If you want to magnify the image, do it in the camera.
