I made a hyperfocal distance table a while back which I like to keep in my camera bag. It allows you to accurately select an aperture to keep foreground and background (to infinity) in focus. I find that a piece of paper is much more useful than a hyperfocal distance calculator app because it is faster, won’t break when you drop it in salt water, and allows you to instantly see what you need to change to get what you want in focus.
Hyperfocal Distance Table for 35mm Full Frame
Sheet 1 is set up for Full Frame, and sheet 2 for APS-C. The top number in each block is the minimum distance that will stay in focus. The bottom number is the distance to set the lens focus to.
I printed the workbook double sided and laminated it. Modify the focal lengths on the left to suit your needs.
This tutorial will show you how to increase the number of steps of volume control in Android. The default number of steps (for music/media volume) is 15, which is fine for most people. However, I have a pair of headphones which are very loud even at the lowest volume setting, so I changed it to 30 steps.
I have been developing a dolly for shooting timelapses for a few months. My goal was a low cost and lightweight system that was portable enough to be backpacked with. While both the mechanical and electronic aspects are a work in progress, the rail is at the state of being usable in the field.
