Setting the correct exposure is one of the most fundamental of photography. With the inbuilt light meters in our camera’s, this becomes a piece of cake as we no longer need to work by the Sunny 16 or any other gothic rule. However over dependence on these inbuilt meters have meant most of the amateur photographers not able to count exposure mentally in terms of stops.
This ability to increase or decrease the exposure by stops comes in handy when one is trying his/her hand at really long exposures. Once you put a dense enough Neutral Density(ND) filter, you will need to count back in stops so as to determine the correct exposure. Depending on the density of your ND filter, this may demand to count back up-to 10 or more stops. Now if you’re sound of your knowledge about the aperture & shutter-speed scale, then you’ll breeze through. Else you might go for the trial & error method. However, the trial & error method would take sometime before you figure out the correct exposure. Instead, use ‘Exposure Calculator‘.
Exposure Calculator is a nifty android application which allows one to calculate exposure for long exposures. One needs to simply input the current correct exposure settings(indicated by your camera’s inbuilt meter) in the top part of the application after which you input the density of your ND filter in stops & you’ve your new exposure automatically calculated for you at the bottom. Makes sure you input the correct settings in the first place else your exposure will be skewed.
That’s it! Now if maths was not your favourite subject in high school, simply use the ‘Exposure Calculator’ & give all the worries of your calculation to your maths teacher.🙂
When I was starting in Photography, I had no clue as to how shutter-speed, aperture & ISO affect the exposure. I had no idea as to why or when to one open up aperture or to raise or lower the ISO. Gradually with trial & errors along-with some reading up, I got grasp over these three elements of the exposure triangle. As the adage goes, when your basics are strong you can make better progress. I often feel most amateur photographers just blindly shoot without learning these basics as they feel them to be boring. Its partly true but that does not mean one should ignore them as every great photographer has these three elements deep sculpted in his mind. With “Right Click”, one can now no longer make any excuses for learning the ABC’s of Photography.
Right Click is an Android application which teaches you the basics of photography. It has two modes – View Mode & Read Mode. Under View mode, one can see the effects of change in aperture, ISO & shutter-speed. All illustrated by amazing visualizations. Under read mode, you can read in brief about them. The best thing about this app is the camera interface which mimics the Canon & Nikon DSLR’s screens so beginners will feel right at home. Apart from the basics, the app also briefs you on various genres of photography which I recommend reading. If you’re a beginner chances are that you’ve not yet found the genre of your liking in photography. Even if you’re not, each genre lists some handy tips which will help you shoot the particular genre with ease.
With the popularity of Android smart-phones, this application will find many takers. However there are a few typos within the read mode which need to be resurrected by the developers. Further I would like the application to provide some challenges to users like throwing up a scene & letting users set the ISO, exposure, aperture for the same. Furthermore expanding on the read mode will be a great addition. Also when user goes into read mode, the orientation changes from landscape to portrait which can be irritating. Else nothing much to complain. This tiny application will come very handy for someone starting with manual photography. And did I say, it offers all this for Free? If you’re beginner in photography & have an Android smart-phone, Right Click is an app you should definitely install.
