I haven't written anything about photography for a while, so I feel it's the time to fix it. After all, when, if not when the new generation of Galaxy S has arrived?
Zoom
The Samsung Galaxy S20+ has 3 cameras: main, wide angle and zoom.
So first we look at the zoom camera.
I took 3 photos for you, each with a different zoom. So my S20 + should always use a different camera module.
As you can see, there is half the street on the widest focus, 3 houses on the basic module and 3 windows on the zoom.
Let's see what it looks like if we put the 3 photos on top of each other:
Here it is even better to see the difference between modules. So don't be afraid to use all three modules. Switch between them easily by clicking the tree icon. The fewer trees, the more detailed you take a photo.
But beware! This applies if there is enough light! Under low light conditions, the wide-angle (f / 2.2) and telephoto (f / 2.0) lenses will appear less bright. It doesn't seem like that, because the basic lens has an f / 1.8, but even this few difference indicate almost half the light transmission of a wide-angle lens.
Of course, if you need a wide shot, the widescreen module is irreplaceable, but if you want to zoom, consider if you prefer to use cropping or just have less detail.
Aspect Ratio
And now let's look at another setting, namely the aspect ratio. You may have noticed that the camera settings only have the option to set the resolution for video, but no longer for photos. All that is available is the aspect ratio setting. We can choose from ratios of 4: 3, 16: 9, 1: 1 and Full.
What is what and when to use? Again we will first show the pictures:
Well, what's going on? The table with the resolution of each picture will tell us more:
As we can see, the 4:3 aspect ratio has the highest resolution. 1:1 is the same in height but smaller in width, then 16:9 and Full are preserved in width, but the height is reduced.
Here is again one picture with all images:
The whole photo is 4:3, others are highlighted by colored rectangles. Here I would like to point out that, as in the first case with zoom, I did not just paint lines into one photo, but I really stacked the individual photos on top of each other. After all, it's a bit visible, because I don't have a proper tripod at home right now, so the cell phone moved a bit during the photo shoot.
The 4:3 aspect ratio uses the entire area of the chip, other ratios crop the photo.
So the idea is to always take photos in a 4: 3 ratio and if necessary crop the photos at home. I recommend it and I do it, but there are exceptions.
We can use the 1:1 aspect ratio if we know we want to share the photo only on Instagram.
The 16:9 aspect ratio makes sense if we present photos on TV (they usually have this aspect ratio).
Full uses exactly the entire area of the mobile phone display, if we show photos on it, it makes sense.
But it is important to realize that anything other than 4:3 means irreversibly discarding some information.
Your articles are always impressing me - every time I read one of your articles I sometimes wonder if I am worth the great camera on my phone's as the photography novice that I am
Keep up the great work!
Thanks, a feedback is very important for me. If you have some questions or idear for article, don't hesitate to send me a message!
64Mpx camera has better resolution but a little worst aperture. Next, the pictures are too big (MB) and everything is slower. You also cannot switch easy to wide camera as it doesn't have 64MPx. So I beliewe that my suggestion is correct. 64Mpx has sense for landscape etc.
Next, the sensor has 64Mpx but the lenses are too small to feed it. My mirrorless camera (fullframe) has significantly bigger lenses and it's resolution is only 47Mpx... I believe that 12Mpx is enough 
About HEIF. The support of this format is not perfect. E.g. some applications don't respect orientation. Instead of using a format saving space rather push to Samsung to increase storage size. I think that 256GB shoul be minimum in 2020. Next, I don't trust miraculous formats and applications.
I tried to make a photo of a car to see it's number plate with the 108mp camera (somewhere far, far away) but the quality seemed to be lost when it came to details after zooming in. While I put it on 4:3 the number plate was surprisingly readable with ease
(Due to focus, and smart processing on the background ).
