![]() ![]() We wrote some articles on how to get more out of the app. To reset a single adjustment control value, double-tap on the control’s button. To reset all of the values, simply double-tap on the viewfinder. How do I reset values set with the adjustment controls? (To unlock all controls simply double-tap the viewfinder). Exposure value locked and both ISO + Shutter Speed unlocked, or.both ISO + Shutter Speed values locked but Exposure unlocked,.With the way the phone's camera system works, setting Exposure is essentially automatically setting ISO and Shutter Speed values under the hood, so manually setting ISO and Shutter Speed is just overriding what the Exposure control sets. If you set Exposure, then Shutter Speed and ISO become unlocked. When you set Shutter Speed and/or ISO, Exposure becomes unlocked. Why can't I set a manual value on the Shutter Speed, ISO, and Exposure controls at the same time? The values are listed in fractions of a second, or even as slow as 1 second on some phones. With faster shutter speeds, the scene is darker and moving subjects are sharper. With slower shutter speeds, the scene is generally brighter and moving subjects will show motion blur. Shutter speed controls how long the sensor is being exposed to light. Generally you'll want to keep the ISO as low as possible, as this allows for the most dynamic range. As you increase the ISO, your photos gain noise. The higher the number, the less light is needed to expose a photo. ISO is how sensitive the camera sensor (used to be film) is to light. They key to these two settings is finding the right balance between the two in order to achieve the image result desired. That leaves us with the ability to adjust the ISO and Shutter Speed to manually control an exposure. This is because the aperture value on your phone is fixed and cannot be adjusted. Now, you'll notice both SS (shutter speed) and ISO in the manual controls bar, but Aperture is missing. Exposure is a balance between three different settings on your camera - shutter speed, ISO, and aperture - which dictate how much light is let in to expose your image. To understand the next controls, you’ll need a quick rundown on how images are produced by a traditional camera. In the following example images, f-stop and shutter speed remain constant while ISO increases in 1 stop intervals from 200 through 800. A 1 stop decrease in ISO cuts the signal amplification in half producing a darker image with less noise. This one’s simple-it brightens your image if you slide to the positive values on the right and darkens as you move to the left. A 1 stop increase in ISO doubles the signal amplification producing a brighter image with more noise. The exposure tool is the middle control in the manual controls bar. Be sure to read this thoroughly! EV (exposure) This article goes over some of the most important tools to master: exposure and manual controls. In this short tutorial video we’ll show you how to adjust the shutter, aperture and ISO on your Nikon camera. ![]() Basics - Manual Controls (exposure, ISO, shutter speed) ![]()
