Serious Android photographers need a serious camera app that offers advanced functionality and is not overloaded with useless features. They need something like Focal. This open source app is still at an early stage of development, but it already shows a lot of promise, and it has the potential to become a viable alternative for Android photography enthusiasts.
Focal features a streamlined interface which makes it easy to take photos and operate the app. To change the focus point, tap on the desired area on the screen, then tap the Shutter button to take a photo. To switch between the supported shooting mode, tap and hold the Shutter button, then swipe up to activate the semi-circle with the available shooting modes. Slide the finger to the desired mode to enable it. Besides Panorama and Video, Focal supports the so-called PicSphere mode which is an open source implementation of Google’s popular Photo Sphere feature that allows you to snap multiple photos in every direction and then automatically stitch them into a single panorama image.
Focal allows you to quickly preview taken photos by swiping down from the top of the screen. This displays a thumbnail gallery which you can browse by swiping forward and backward. The gallery features two buttons that can be used to open the currently viewed photo in an external photo viewer or photo editing app.
To access Focal’s options, swipe from left to right starting at the edge of the screen to evoke the main toolbar. Each button on the toolbar opens a palette containing the available options. Most buttons here — such as White Balance, Exposure Compensation, ISO, and Flash — should be familiar to most photographers. Using the appropriate buttons, you can select between different scene modes and effects. The HDR button lets you enable the HDR feature which automatically takes three bracketed photos. Focal supports several burst modes, and you can use the Burst button to enable the burst mode you want. Each palette can be pinned to the screen, making it easier to quickly access often-used options. Better still, all settings adjustments are persistent, so you don’t have to enable and configure the options every time you start the app.
Since Focal is still labeled as beta, some features are still missing. For example, the app doesn’t support different focus modes (manual, macro, etc.) and there is no way to change the default storage location. Moreover, some features can behave erratically. The PicSphere, in particular, can be rather temperamental at times.
Recently, I bought an EPSON Perfection V500 scanner, and I spent last weekend scanning piles of negatives. One thing about scanning negatives is that it involves a lot of waiting: you click the Scan button and then wait till the contraption does its scanning thing.
Meanwhile, you need to find a diversion to keep you entertained. Having a good game app for Android would definitely help. And after rummaging through the F-Droid repository, I found a perfect candidate for the job. FreeShisen is based on the Shisen-Sho Japanese game. The game has a lot in common with the popular tile-based game of Mahjong, but it has more elaborate tiles and rules.
Despite that, you can master the game’s basics in a matter of minutes. Depending on the level of difficulty and your skills, a single game usually takes between 5-10 minutes — perfect for passing time between scans. The app is open source and available through F-Droid and Google Play Store.
While you can use a regular notebook to keep track of exposure info (shutter speed, aperture, focal length, etc.), it’s hardly an ideal solution. But if you happen to use an Android device, you can replace the notebook with the Exif4Film app from Code United to simplify the task of recording exposure info and applying it to scanned photos.
The app is available free of charge from the Google Play Store. During the first run, the app prompts you to import the film database containing pretty much every film in existence. Next, you need to add your photographic equipment (cameras, lenses, and filters) to the app. To do this, tap the Menu button and choose Gear. Tap the Add gear button, pick the desired item, and fill out the required fields. When adding a camera, you can specify which lenses in the database can be used with it. This works for lenses, too: when adding a lens, you can select the cameras that can be used with it. When you are done, press Save to add the equipment item to the database. Once you’ve added your gear, return to the main section, tap the Add roll button, and provide the required info. Press Save to add the roll, and you are good to go.
Recording exposure info with Exif4Film couldn’t be easier. As soon as you take a shot, open Exif4Film, select the roll, tap Add to add a new exposure, and enter its values. In addition to the standard values like aperture, shutter speed, focal length, exposure compensation, etc., the app automatically records the geographical coordinates (useful for geotagging photos). Exif4Film also lets you take a photo and attach it to the current exposure. When you add the next exposure, the app automatically populates the fields with values from the previous entry. This can be a real time-saver when you take several photos with the same camera settings.
Exif4Film features other creature comforts, too. The View on map button displays the roll on a map complete with markers for each exposure. When you finish the film roll and record the time when it has been unloaded in Exif4Film, the app conveniently changes the roll’s icon, so you can easily identify the active and processed rolls in the list.
As you keep adding rolls to the database, managing them may become increasingly difficult. This is where the app’s filtering functionality can come in rather handy. Using it, you can display only the rolls that match specific criteria, such as camera model, film, and loaded/unloaded dates.
Exif4Film also has a companion desktop utility which can help you to import the recorded exposure into the scanned photos. To do this, you need to export data from a specific roll first. Tap the Export button in the Exif4Film app, select the desired roll, and tap Export. You can then export the data to a file on the device or Dropbox. Transfer the exported .xml file to your machine, launch the Exif4Film desktop utility and use it to write exposure info to the scanned photos. The utility is simplicity itself, so you shouldn’t have problems figuring out how to use it.
If you are looking for a no-frills depth of field calculator app for Android, you can do much worse than giving the DoF Calculator a try. Released under the GPLv3 license, this app has the virtue of doing one thing well: calculating the depth of field and limit values for any given camera model, lens focal length, and distance to the subject combination.
DoF Calculator is not available in the Google Play Store, but you can either sideload it using the latest APK package from the project’s website, or install the app through the F-Droid market. Unsurprisingly, DoF Calculator is very straightforward in use: pick the desired camera model, focal length, aperture, and the distance to the subject, and tap the Calculate button. The app then returns three values: near and far limits along with the total depth of field.
The Camera FV-5 app is designed for serious photographers, and as such, it lacks fancy trimmings like scene modes, effects, and sharing capabilities. Instead, it puts all essential controls at your fingertips, and offers a handful of genuinely useful features. Camera FV-5′s interface resembles that of a DSLR camera, so photographers will feel right at home using the app. The main screen provides quick access to key settings, such as focusing mode, metering mode, White Balance, ISO settings, and exposure compensation. The dedicated Menu button lets you configure the exposure bracketing feature and intervalometer. The latter tool can come in rather useful for time-lapse photography. The Program button can be used to switch between two modes: Program (automatic exposure) and Speed priority (manual exposure). You can use the pinch gesture to zoom in and out. The app also allows you to use volume hardware keys for zooming.
Besides the efficient interface, Camera FV-5 boasts several unique features. For starters, the Camera FV-5 can save captured photos in the lossless PNG format. This is a real boon if you plan to post-process photos using your photo processing software of choice. The app can write metadata into the photos or separate XML sidecar files (or both). Saving captured photos in the PNG format is a resource-intensive task but the app processes the images in the background without affecting Camera FV-5′s overall performance. The app also sports long exposure functionality (which does have certain limitations), which is perfect for low-light and night photography.
In short, Camera FV-5 is a perfect camera app for Android-totting enthusiasts or serious photographers. A free version of the app is available on the Google Play Store, so you can give Camera FV-5 a try and see whether it fits your needs.
This app is designed to help you manage your Piwigo gallery from the convenience of your Android device. As such it doesn’t allow you to browse albums and view photos (to do that you might want to give the ReGalAndroid app a try). The app itself is pretty straightforward in use. First off, you have to connect the app to your Piwigo instance, which is done in the Settings section. The Album view lets you select an existing album and change its permissions, create new albums, and upload photos.
Before you can upload photos, you have to select them in the Photos view. Here, you can also edit the title, author, and description for each selected photo. Once you are done, press the Upload button and the app will do the rest. That’s all there is to it. The Piwigo app is not exactly overloaded with features, but it gets the job done with a minimum of fuss.
