Camera: how to use manual mode, Aperture, ISO speed setting

the majority of Android smartphones now offer a manual (or pro) mode for the camera. It allows to take hold of more settings than the automatic mode and, in certain circumstances, to achieve more beautiful pictures because it is you who set up all the parameters of the shooting. And the good news is that you don’t need to have any monstrous knowledge to master.

Why use manual mode?

Most users just yet the automatic mode for take pictures with their smartphone . All settings are already pre-set depending on the ambient light conditions and most of the time, it does the job. But since our Android smartphones have become photophones, sensors on the back are not only there for the deal, they also enable us to make beautiful pictures. Still need to know to use them.

By opting for the manual mode, you then take the hand on all settings allowed by your Builder (we return to this point later) and you control all the parameters of your image, which gives you the opportunity to exceed the limits of the automatic mode.

you control even exposure

before firing the shot, your smartphone photo sensor will first calculate the ambient light. From there, he will decide whether to trigger the flash (if it is set to automatic mode) but will decide also to lower or increase the brightness of your shot. In automatic mode, still the majority of smartphones tend to overexpose photos.

In low light, it helps to get a better result but in full sun, it sometimes gives the effect of a burned photo or whites appear too white. Best is to set it yourself exposure. On the latest Samsung Galaxy, it is very easy to do, it just drag the finger either upwards, downwards, on other smartphones, it will open a small menu and select + or-.

Attention to the flash

as on a ‘real’ camera, the flash found on smartphones is very convenient since it allows to shed further light on the photos taken in low light. Most of the time, it is set to automatic mode and fires so only when the sensor decides that the brightness is too low. At night, it remains essential, but it can happen that your smartphone the triggers in daylight, especially indoors.

In these circumstances, it may be useful, as it can literally ruin your photo by generating too high exposure and producing colors that come natural. If you have a doubt, the best is yet to try with and without. But you will see that most of the time, is the photo without flash, which will be the most successful.

ISO, do not not overdo!

Most of the Android smartphones now offer very good ISO sensitivity. But then again, in automatic mode, the sensor tends to overestimate your photo needs, choosing sometimes ISO too strong. Yet, in an enlightened environment, it is not necessary to climb above ISO 200, value from which the noise is likely to appear in the shots, making them less net.

If you have really good light, the better is still down at 50 ISO, if your smartphone allows to 100 ISO, your photo will be only sharper.

Sensors photos smartphones: autofocus, exposure, all what you need to know

choose the right balance of white

(indicated by WB) the white balance is automatically calculated by your smartphone. Based on the ambient light, the sensor then adjusts the colors in the photo to make them as close as possible to reality, but here, again, depending on the light conditions, the sensor has its limits. Fortunately, it is possible to set it manually.

This setting can sometimes seem complex insofar as it is again whenever the light conditions vary, but it can change everything in the final result.

Shutter speed

more and more smartphones now allow the Google API Camera2 manual controls, you can set the shutter speed, mean by that, the period of time during which the shutter is going to let the light in the sensor. As you can see, on the photos taken in full sun, this time is very short and at night, it is long since light needs more time to cross the sensor.

but you can also play with to obtain different artistic effects on your photos. Unfortunately, at the present time, all manufacturers do not yet allow this setting in their photo applications. To find out if your smartphone allows, you can download the application Manual Camera Compatibility in the Google Play Store . Note that it is also this API that allows you to out your photos in format RAW uncompressed .
