Knowing how long to develop film for is easy if you use popular films and developers, but what if you want to use some obscure combination that isn’t well documented? If that’s you, check out the Photocritic Film Development Database. It’s a simple service that outputs development times for 1440 different film/developer combinations. For combinations that aren’t officially published, creator Haje Jan Kamps has come with a formula that estimates the time — a formula that he says is surprisingly accurate.
Knobroom is a free add-on for Lightroom that lets you use the knobs and sliders on a MIDI Controller to edit photos in Lightroom. Unlike PADDY, which we featured last year, Knobroom is also available to Mac users. The brief demo above shows Lightroom being controlled with a Behringer BCF2000. Freelance photographer Max Edin has written up an informative review on setting up and using the add-on.
Having trouble framing shots when “shooting from the hip” and not looking through (or at) your camera? Lifehacker suggests pointing with your left hand index finger to improve your accuracy. Simply press the finger against your lens, parallel to your camera’s line of sight. The idea is that while we point at things all the time, aiming a camera isn’t quite as intuitive (though it comes with practice). By making the camera an “extension of your body”, you might be able to aim it more naturally!
We’ve featured special gloves and mittens designed for photographers before, but what if your camera uses a touchscreen instead of physical controls? Here’s a video by Make’s Becky Stern showing how you can sew some conductive thread into your glove to make it compatible with capacitive touchscreens. Video after the jump
Src Img is an uber-simple bookmarklet created by Jarred Bishop and Hayden Hunter that lets you quickly do a Google Image search for any online photograph with just two clicks. It’s a simple link (i.e. bookmarklet) that you drag into the bookmarks bar of your browser. Whenever you want to search Google Images for a particular photograph, simply click the bookmarklet. It’ll overlay all the photos on the page with a “?¿” square. Click this to search for that photo. Voila!
Mirrorless cameras are designed to be compact, but how big are they compared to DSLRs? How big are popular DSLRs compared to one another? Camera Size is a website that helps answer these types of questions. It’s a simple web app that shows you exactly how big digital cameras are compared to one another and compared to reference objects (e.g. a battery). Read more…
Dan Bailey over at The Photoletariat captured this brief video of Lowepro showing off its new Lens Exchange 200AW case at PhotoPlus Expo in NYC. The case is designed to help you swap lenses with one hand — instead of setting one lens down before taking out the new one, it expands to reveal a second compartment. Stick the old lens in, pull the new lens out, and then collapse the case back into its compact form.
Want to know how long it’ll take you to save up for that camera or lens you’ve been dreaming of buying? grndctrl, an uber-simple personal finance web app, can tell you. It doesn’t take any personal details, but simply asks for your income, expenses, and savings amounts. You can then provide it with a list of “rewards” that you’d like to save up for, and it will give you estimates of how long you’ll need to wait.
Zoom creep is what happens when gravity causes your lens to zoom in or out due to it being pointed up or down. While it’s not really an issue when you’re shooting hand-held, it can cause problems if you’re trying to keep the zoom fixed while the camera’s on a tripod. A trick to combat this is to use rubber bands to keep the zoom ring still, but now there’s a fancier solution to this problem: the Lens Band. It’s a gel bracelet-style band that’s wrapped around the zoom ring when not needed. When you want to freeze the zoom, simply slide half of the band over the lens body.
They’re available in a variety of colors and sizes to fit most lenses, and cost $5 each from the Lens Band website.
Adobe’s amazing Image Deblurring demo was the star of the Sneak Peeks event at Adobe MAX 2011, but it was just one of the many demos shown that night. Another interesting photography-related demo was for “Pixel Nuggets”: a feature that lets you search a large library of photos for features (e.g. people, landmarks, patterns, logos). Read more…
