Question Stock camera low resolution pictures - Samsung Galaxy S21 Ultra

Hi all, I noticed that jpeg pictures taken with stock camera, even at 108mega pixels are not so large, the are around 4mb. I also have gcam installed and the ones taken with it are 44mb.
No way to increase stock camera quality?

Using stock camera the image file size is approx 36 Mb when selecting 108Mb camera on my S21U (SM-S998B).
Selecting HEIF format reduces it to 30Mb.

Yes, mine to. But if selecting 12mp the image become 4 mb

You can enable 108mpx in aspect ratio select, you will get 30MB Picture as you expect

Dear jacopastorius, JPEG is a low-resolution image format. If you want a high-quality image, you should try png, which is used for high-resolution images.

Improving the stock "gallery" app

Is there any way to improve the gallery app by allowing the zooming of images upto 100% of their resolution? Even photos taken with the camera, if you zoom in, the quality looks crap because of the downscaled image.
I heard somewhere that this bug is fixed in Froyo - but can't remember where exactly

[Q] How camera sensor works

So I was thinking about something lately. We have that 13Mp camera (Nothing super in terms of the quality) But what does the phone or lens when you put in on like 8Mp. Is it that it makes a 13Mp and crop it? Or can it be used to use multiple pixels as one? Or does it just shutdown those?
Question that I have for some time now
it's image sensor
the quality of photo depends upon image sensor the bigger the image sensor the better photo u will get:laugh:

It uses 8 Mp of these 13 Mp, which produces a smaller image size. Use all 13 Mp and then resize it manually to the required size. For best image quality do this on a PC.

[Q] Photo Size

Hello,
I clicked some photos using the rear camera. The specs suggest the photos should be either 6 MB or 8 MB.
What I am getting are really low resoultions photos ~ 1.5 MB.
Is there a setting that needs to be switched on to get the size up?
The pictures should be 6 or 8 megapixels, not megabytes.
If you're taking pictures with a 4:3 aspect ratio, then it will be 8MP (3264x2448). If you're taking them with a 16:9 ratio, the pictures will be cropped to 6MP. The file size is not the same as the number of megapixels.

Which resolution is best for photos/videos?

According to "OpenCamera" I am using a 4160x3120 resolution when taking pictures.
This isnt a wide-screen resolution and I wonder if that makes any difference quality wise? Can I just stick to this resolution or should I go for a 16:9 reaolution (4160x2130) ?
Thanks !
Wide screen mode on the camera is the equivalent of taking a 4:3 image and cropping it in Adobe Photoshop. The image has fewer pixels after cropping, which is why the stock camera and some other camera apps make a big deal of pointing out the resolution at each setting. You don't lose anything in terms of quality as you are taking the image with a 13MP sensor. The software simply discards the unused data.
The setting is a matter of personal preference. I keep mine on wide screen despite the data loss because I like it. If you like it, set it and snap away. Otherwise stick with 4:3.

General [CLOSED]GCam 16MP, 64MP and Raw compared

I downloaded the Wichaya_V1.4 GCam on my Zenphone 8 and found that it can record 64MP jpegs as well as the normal 16MP and Raw file options.
I did a quick test to compare the quality and usability of each version: I took a simple shot that included highlight, shadow, fine detail and strong/subtle colours. The attached screen-grabs are from a small central area of the picture.
The storage size of the shots are 1.8MB. 6.2MB and 13.7MB respectively, so the Raw file is over 7x the size of the smaller jpeg. All details are shown at the same size so the quality and sharpness can be compared.
I found that the 64MP jpeg was both softer and grainier than the normal 16MP file. I sharpened it a little but I don’t think it offers any advantage over the smaller file because of the graininess. If you want a more retro film grain look this could be an advantage.
Straight from the camera the Raw/Dng file is very flat and requires post processing to get it into shape. It’s a 16MP file that contains far more information than the jpeg that’s recorded with it. I opened it in a Capture One (Lightroom or Affinity Photo, etc could be used) and spent time adjusting parameters to get what I considered to be the best version of the shot. There may be smartphone apps that could be used, but I prefer to do this on my laptop.
The outcome is that I will continue to shoot most pictures as normal 16MP jpegs but whenever there is something very special that I wish to capture I’ll switch to Raw + Jpeg mode. This gives me the regular Jpeg for reference and a Raw file to process later when I want to create the best quality of picture from the GCam.
Thank you for your review. Can you add 64MP RAW and process it? It should give some extra details.

A 64MP Raw option would be interesting and theoretically lead to higher quality results after post processing. Best to make a request to the developer, Wichaya.
I'm interested in getting the Zenfone 8. Does OpenCamera shoot in 64mp? I'd love to see some examples!

I don't know if Open camera can record 64MP images as this is not mentioned on its website, but it's free to download and worth trying out. In a previous post I compared the GCam, Asus camera and Open camera night shots. The Open camera gave poor results so I personally would not use it as the quality of low light shots is important to me.

Switch to 64MP mode in the GCam interface, not in the Wichaya settings. See Screenshot,
