How to know the spare battery in your camera bag's at full power

    Unless you're using your cellphone as your camera, batteries are going to be one of those accessories you'll need for your camera.

    It's usually a good idea to have more than one battery for your camera, as it gives you backup if you are out shooting for an extended period.

    But with multiple batteries you need to come up with a way to ensure that your batteries are fully charged. Trust me, there's nothing more frustrating than being out shooting and discovering that your spares are deader than Elvis.

    There are a few methods for doing this. One involves putting a little stick-on slider device on the battery, where the green side means the battery's good and the red side means the battery is due for a date with the charger.

    Those work fine if the battery clips to the outside of the camera or light body. My wife's camcorder batteries are mounted on the outside, so a setup like that would work just fine.

    But this doesn't work with the tight tolerances of an internal battery compartment.

    I've come up with a simple system, particularly after acquiring a second camera body and purchasing additional batteries for it.

    First, I've numbered each battery to ensure that they're all getting equal wear and tear, as well as knowing that the next number in sequence should have a full charge.

    Then, I added a rubber band to the battery and the plastic bag it sits in. If the battery's good to go, the band is wrapped around the bag. If the battery's spent, I put the rubber band in the bag with the battery, giving me an additional visual cue.

    I do something similar with the rechargeable AA batteries I use for my voice recorder and speedlight. If the batteries are wrapped with a rubber band, they're charged. If they're loose in their bag, then they're dead soldiers.

    What are your suggestions for tracking your batteries?

Need to RTFM? There's an app for that

    For a lot of people, the manual that comes with your camera or other equipment might be something you read once — if at all —and put it away.

    But with today's cameras being essentially computers with a lens, it doesn't hurt to keep the manual handy, especially when you need to remember how to use a feature that you've only operated occasionally.

    The obvious answer is to keep the camera manual in your bag, but that puts additional wear and tear on a cheaply made paperback. Heck, even the cover's paper, so it's not going to last too long in your bag.

    Or you might be like me, and there's no room in your bag for all the gear you carry.

    (For the record, I've never regretted having something in there and not using it. On the other hand, I've kicked myself plenty of times because I didn't have a piece of gear I realized I needed.)

    But there's a high tech way to carry the manual for every piece of kit you have without it taking up any additional room, or getting chewed to pieces in your bag.

    Every manufacturer has downloadable PDFs for their manuals on their websites. All you need to do is log in with your phone/tablet and download the file, where you can read it using a PDF reader on your phone.

    Personally, I also upload the books on to Play Books, Google's e-book reader, which can also handle PDFs. It allows me to access the books from my phone or any computer. You can do the same with the Books app on the iPhone.

    Since there's also a local copy on my phone, I can access the files on my phone even if there's no service.

    In addition to my camera manuals, I also have the instructions for my digital recorder and my speedlight on the virtual bookshelf.

Recycle film canister as DSLR pop-up flash diffuser.

    While the pop-up flash on many DSLRs are a way to get some extra light in a picture, it's not the best.

    These flashes, which take up the top part of the pentaprism, are typically tiny and work best at the range of 12 feet. It's also a hard light, which means a subject is going to have hard shadows around it and be harshly lit.

    I only use mine in situations where there's no other way to get the picture or as a wireless trigger for other flashes.

    But over on Instructables, user deth2all presents a way to take some of the harsh edge off the pop-up's light, and even add some color to it as well. And if you used to do a lot of film shooting with Fujifilm, or know someone who did, you can get the main part you're going to need.

   (deth2all/cc-by-sa)

    The diffuser consists of the plastic film canister that protected the film cartridge before use and later when sitting in your gadget bag. It has to be Fujifilm, which used a white, translucent plastic to make its cases; Kodak's canisters are all black.

    The project involves cutting away part of the canister's side wall, so it can fit over the flash head. He also cuts a slot in the side of the cap, which is glued back in. That slot is used to insert a colored gel for various effects, as well as balancing the flash with another light source.

    (He recommends getting sample packs of gels from art-supply stores, but those have since stopped providing them. You can make some of your own by cutting up colored plastic report covers.)

    The results he posted on the site show some reasonably good results. If you're looking to improve your flash photography but aren't ready to make the leap to speed lights, this is a good option.

Getting 360-degree panoramas with your cellphone with help from Google

    We've all seen those photos on Google Earth and Street View that show a 360-degree panorama of a subject.

    It gives you a chance to see an area as if you were actually there. When my wife and I were house-hunting after I had gone ahead for a job, we would use Street View to take virtual driving tours of neighborhoods where we were looking to buy, so we could both get a sense of the area.

    While Google uses a sophisticated camera mounted on a car, or backpack for trail views, and dedicated 360-degree cameras are in the triple digits, you can do it yourself inexpensively if you have a cellphone camera.

    If you use an Android (sorry, iPhone users), you can get a VPai Clip for your phone. The golf-ball-sized device, which I got online for less than $20, is not a camera as much as it is a pair of lenses for your cellphone. Each lens captures a 210-degree field of view.

    I know what you're thinking: That adds up to 420 degrees, and a full circle's only 360 degrees. Well, those additional 60 degrees allows the software you download on your phone to overlap and seamlessly stich the pictures together to create a 360-degree photo that you can see as a panorama, a sphere or a "little planet."

    If your phone's only capable of FHD video resolution, the image quality may not be the greatest and you'll have to upsize it to post it on Google Street view, but in the words of Krusty the Clown, it's not just good, it's good enough. Check out this one I did recently.

    But if you're using an iPhone, or don't want to get an attachment for your phone, Street View has you covered.

    The Google app has an option that allows you to use your camera's full resolution and optics to capture a photo sphere. It takes patience, a willingness to have people think you're a bit insane and a pair of steady hands.

    When you go to take a picture, the app will display a dot on the screen for you to line up on, and when you line up it takes the picture and moves the dot to the next spot. Eventually, you'll do a full 360-degree arc horizontally and vertically.

    If you do this, it's important to stay in one spot and turn in place, otherwise it won't quite line up as well, and you might miss spots, as I did in this one of the Alamo.

    Or this one in the torpedo room of the USS Blueback in Portland, Ore.

    But if things work out, you get a reasonably good shot, like this one:

Binoculars give your cellphone real telephoto

    For many people, cellphones are their cameras.

    On the one hand, most of us always have them with us, they're stupid simple to operate and, depending on your phone, can produce a decent picture.

    But they have a few drawbacks. The most obvious one is that most of them don't have an actual telephoto function.

    Most cellphone cameras give you the option to zoom in, but that is a digital zoom. Rather than actually magnifying the image as an optical zoom lens does, digital zooming merely crops the picture and then stretches that part of the image across the "canvas" of the image. That might be fine for a minor adjustment, but if you're really trying to see something far off, it is going to be a pixelated mess.

    Frankly, I consider digital zoom as one of the great frauds perpetrated upon consumers.

    But I saw someone suggest a way to get a relatively decent optical telephoto with a cellphone camera. It involves using binoculars.

    What you do is first focus your binoculars on the subject you're looking at, and then put the cellphone's camera lens against one of the eyepieces and take your picture.

    You get a picture that covers a small part of the sensor, but it's a true optical enlargement of the image. You can crop it and it still looks more decent than a digital zoom.

    Here's a few shots I did to test this.

 

This one is with the camera at its default focal length.

 

Now, we're looking through the binocular eyepiece and you can see the enlargement of the image.

 

 

Cropped to make it square.

    It's not the sharpest image, but it is better than what you would get with digital zoom.

    The biggest challenge is juggling the binocular and cellphone, especially if you can't rest the binoculars on a steady object, like a railing. And since you are using an extreme focal length in comparison to your sensor size (unless you're using a high-end cellphone, your sensor's going to be about as big as the fingernail on your pinkie), any minor movement in your hands is going to make it shake like a major earthquake.

    But it offers a way to get a close-up view. You can also use this technique on a telescope if you want to get a close-up picture of the Moon with your phone.
