Use “Focus Peaking” in Photoshop to Select In-Focus Areas of a Photo

Last week, we wrote about an emerging digital camera feature called “focus peaking”, which lets users easily focus lenses through live view by using colorful pixels to highlight in-focus areas. Photographer Karel Donk wanted the same feature in Photoshop, which doesn’t currently offer it, so he decided to create it himself.

Make a Film Roll Bandolier to Make Sure You Never Run Out of Shots

Bandoliers are pocketed belts made for holding ammunition. They’re often seen in action and war movies, slung over the chests of tough guys holding big guns. If you’d like to ensure that you never run out of photographic ammo (AKA film) when you’re out and about, you can make yourself a nifty DIY film ammo strap. Photojojo says that these are inspired by old school camera straps that come with elastic film loops, but we definitely think you should go the extra mile and turn them into full-blown bandoliers.

What you’ll need is some fabric and elastic, a key ring to serve as a connector, and some sewing tools and skills. While it’s designed to be attached to your belt or to the strap mount on your camera, adding some extra length to it can turn it into a belt/bandolier. Head on over to Photojojo for the low-down on how to put this thing together!

P.S. We’ve written multiple times before on how there’s a historical link between guns and cameras. Many techniques are interchangeable, there’s shared terminology, and rifle butts have been used as camera stabilizers throughout history

FilterCalc: An Android App for Calculating the Exposure Offsets of Filters

Still shoot film? Use filters when you shoot? FilterCalc is a new Android app that’s designed to help non-TTL photographers figure out proper exposure when using filters.

This base ISO exposure calculator comes with preloaded database of almost 500 filters. By selecting the actual ISO value and filter type, the app computes base ISO to be used with the light meter resulting in proper exposure.

FilterCalc can compute ISO compensation in increments of 1/3, 1/2, 2/3 and full stop EV. You can select compensation values by stops, by filter factor, by preloaded filter brand/type, or add your own custom data.

The app is free and can be downloaded over on Google Play.

Use Your Coffee Cup to Predict Whether Rain Will Ruin Your Outdoor Shoot

Did you know that your morning cup of coffee can help you predict rain? It’s a trick used by backpackers that can come in handy you’re shooting outdoors without Internet: pour a cup of coffee and carefully watch the bubbles. Backpacker Magazine writes,

If the bubbles amass in the center, you’re in a high-pressure system, which is making the coffee’s surface convex (higher in the middle). Since bubbles are mostly air, they migrate to the highest point. It’s going to be a beautiful day. If the bubbles form a ring around the sides of the mug, you’re in a low-pressure system, making the surface concave. Rain is likely. Note: It has to be strong, brewed coffee to have enough oil to work, and the mug must have straight sides.

To make new bubbles, simply give your coffee a good stir.

Nokia’s 41-Megapixel Camera Phone Sensor Compared to Other Sensors

Here’s a great diagram by Mobot that shows how the 41-megapixel sensor inside Nokia’s new 808 PureView phone stacks up against other popular sensor sizes. It’s pretty clear that they didn’t just milk a small sensor for more megapixels as a simply marketing ploy, but instead came up with a sensor that’s significantly larger than those found in other smartphones. Engadget also has a photo showing a comparison of sensor sizes, while Digital Trends has published an article on five reasons why the 41-megapixels isn’t a gimmick.

Use a Marble to Find Good Available Light

Steve 21 has an interesting trick for finding good available light: he places a marble in his hand to simulate what the light would look like on a human face:

Just hold a fist in front of you (like holding a telescope), tuck the marble just under your forefinger, and there you have it – the same lighting an eye would get.

And since you know you want the catchlights to be up at 1 to 2 o’clock, or up high at 12 o’clock, simply turn about until you see the catchlights you want.

The neat thing is that the curves and wrinkles of your hand show you the amount of contrast and backlight.

Black marbles: the latest must-have item in any beginning photographer’s camera bag.
