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?
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.
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.
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!
4:3 uses the main sensor (12Mpx for S20 and S20+, 108 Mpx for Ultra but processed to 12Mpx), 64 uses zoom sensor for S20/S20+ and main sensor for Ultra.
I recomend using 4:3 if possible and switch to higher resolution only when you really need that.
is there any advantage to using just 4:3 and switch to the 64p "when you really need that" vs keeping it 64p all the time (other then file sizes etc) and what is the best "scenario" to switch/choose?
also, im trying to work out should i save files with heif/heic over jpg but enable "convert before sharing" - as some say its better quality and less space, but i want to know if its worth it as i dont want to convert it to jpg and find quality has been lost during conversion compared to jpg directly.
(similar with video, when do we film in hdr10+ locked to 30fps vs "standard hdr" at 60fps, and hevc?)
thanks for the tips, i'll make sure i'll use 4:3 ratio and i can just crop it if i need other ratio.. its easier to crop in then shoot already cropped and loose detail
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.
thanks. Makes sense!
I have 128gb on phone but I'm waiting for amazon to turn up with a 256gb microsd. Couldn't afford the 512gb one as it was 4 times cost and 256gb was on offer lol.
I'll keep it as jpg if its better then saving bit of space. At least until it comes mainstream
The ratio of an image must be thought of according to the destination of the photo.
If the 4/3 ratio uses all the possibilities of the photo sensor, the 16/9 ratio is much more suitable for most smartphone and TV screens, it is also suitable for printing.
If the 16/9 has a slight loss of definition compared to the 4/3 the visual comfort is much better.
