Smartphone cameras have become so good that they are often the entry device for many photography enthusiasts. With cameras becoming powerful, manufacturers are also allowing users to customize camera settings like ISO sensitivity, Aperture, and Shutter speed. If you’re starting out with the basics of photography then you will experiment with these settings quite a bit. If you’re having trouble understanding just what changes made to either one of these settings does when you’re taking a photo, visit Exposure Tool. It’s a very simple online tool that shows you the effect of these settings on a given image and lets you play with them.
Exposure tool comes with an image that can best show the effects of playing with the shutter speed, aperture, and the ISO sensitivity. You can’t upload an image of your choice.
Next to the image, you will see three sliders, one each for Shutter Speed, Aperture, and ISO Sensitivity. By default, the mode selected in the app is ‘Manual’ which allows you to change all three of these sliders independently. As you move the slider, the image changes to reflect how it would appear if it had been captured under those new settings.
If you do not use the Manual mode, and instead try the Shutter Speed Priority mode, or the Aperture Priority mode, you will only be able to change the respective setting that you’ve prioritized and the other two will change to reflect the best setting accordingly.
Exposure tool gives you a fairly accurate idea of what changing a specific setting will do to your photograph without getting technical. You might look up the definition for any of these settings but if you want to watch them in action the tool is pretty helpful.
