Archive for the 'Camera Stuff' CategoryAbout cameras, equipment, and postprocessing techniques As I recently wrote, I love my Nikon 18-200 zoom except that it's a bit "slow", optically speaking: at f/3.5-5.6, the lens diameter is too small to allow enough light for reasonable shutter speeds in low-light situations. So, two weeks ago, I finally picked up a Sigma 30mm f/1.4 prime lens. At f/1.4, it's 3 stops "faster" (optically speaking) than my current lens, meaning it can allow 8 times more light, in turn allowing a shutter speed 8 times faster. That makes it great for low-light situations. A byproduct of a large aperture (low "f" number like [...] 
View full post » I've another tech-related photo writeup, this time on NEF (Nikon raw image format) compression. In it, I look at detail lost during compression in a way I've never seen anyone do it, so if you have a high-end Nikon that can write compressed NEFs, you may find it interesting. (See my Photo Tech page for more technical writeups related to photography.) View full post » The only lens I own for my Nikon D200 is a Nikon "AF-S DX VR Zoom-Nikkor ED 18-200m F3.5-5.6G(IF)," also known as "the 18-200mm." I really love it as a fantastic all-around lens, but at f/3.5-5.6, I find that it is sometimes a bit slow (that is, it doesn't let in enough light for me to use a fast-enough shutter speed). So, I've been thinking of getting a faster (allows in more light) lens for use in lower-light situations. Because of its "18-200mm f/3.5-5.6" name, I know that my lens is f/3.5 at 18mm, and f/5.6 at [...] 
View full post » A commenter on my previous post asked about how I make the borders on the images I post. I'll talk a bit about that here. At first I thought that it was wasteful of screen real-estate to add a border. When printing a picture to hang on the wall, I don't add borders, but I do use colored matting to compliment the picture. That's what I've got in mind when adding borders to images that I post. The real skill involved -- skill that I don't have much of -- is deciding what to do. How to [...] 
View full post » (This post is mostly for the search engines, to help others looking for the solution that this post provides) Lightroom, Adobe's high-volume photo workflow application, stores all kinds of user-preference and per-image data in an SQLite database. As of the Beta 3 release, the database is stored in one file, the Mac filename being "/Users/username/Pictures/Lightroom/Lightroom B3 Library.aglib" If you're technically-minded and want to peek at the database directly, you might try to access it with the sqlite3 command, which comes standard with OSX, and be disappointed to find that it doesn't work: Eric Scouten provided the answer in [...]
