I sometimes need to rotate jpg images on my Android mobile. To avoid image quality degradation what I do now is to copy the image and then use "rotate image" using Gallery (or other) app on the copied image. I later transfer the original to my PC where there are many image viewers to perform lossless rotation.
Is there any Android app that can perform lossless rotation?
If not, can one of the talented developers here create a app to do the same?

Hi all, I tried to do some shots in RAW mode. After the shot I have two files: a JPG and a DNG. The jpg is perfect as always, but the DNG File is pixelate and it's very bad. I asked at the Honor official page and they said that's normal because I'm watching it on my smartphone and that on PC the quality would be different, but is it really normal?
To my knowledge, the phone shows just the jpg thumbnail of the raw file (since it would be quite cpu consuming to "develop" the raw data each time). So if you open the raw file in Lightroom or raw converter, it should be fine. Also if you edit the dng on the phone and save the result as jpg, the jpg quality should be ok. At least this is my experience (I use raw mode quite a lot to later edit the raw files in Lightroom).
So there's no way to see a clear image while elaborating it. I will se the good results only at the end.
What exactly do you mean by "pixelated"? And what app do you use to watch the raw image? On the Honor's builtin Gallery app the dng is quite ok quality. If you use a third-party app, it's possible that it cannot dig the best-quality preview from the dng file.
I mean this
While the jpeg is this
I have tried several apps but they either don't recognise the phone's camera app's DNG format or they are simply useless for other reasons e.g. always writing the output to some directory (folder) in the device filespace which one then has to move them out of.
I need something which can convert them from the SD card
e.g. 0000-0000/DCIM/Camera
to the same place.
The S7 is rooted, with SDfix etc.
I would appreciate any tips. Basically I would like an app which works with the Samsung DNG format and which has configurable in and out folders.
Android v6, not v7, rooted.
If you have RAW enabled in camera settings, the phone also stores a JPEG of the exact same photo, so no need to convert them really
Not sure about Android apps, but on PC just load them into your favourite RAW photo editor and export them as JPEGs (Lightroom for example)
Not quite... taking the DNG and processing it with say Lightroom produces a vastly better quality photo.
See e.g. here for examples

The Jpegs from the phone are over-contrasty and over-sharpened. One should never apply unsharp mask until the image is resized to the final resolution (if at all).
Yes I know that, which is why I suggestion Lightroom
Converting on the phone is not going to give anywhere near the same results as PC Lightroom
Use a PC

The real issue IMHO is that all the camera apps are mostly just control panels for the camera API. They don't AIUI get the image to play with. That is why e.g. all of them have the same contrast steps, same exposure range, etc. The JPG is done by the OS and the app gets what it gets. One camera app developer explained this to me.
Hello.
Many people had a difficulty with opening new iPhone *.heic image files on Android and I have created the app to help them solve this problem.
Now you can open photos from iPhone (.heic) on Android device using Luma: *.heic to jpg converter and viewer offline.
URL: https://play.google.com/store/apps/details?id=luma.hevc.heif.image.viewer.converter
This is simple app which let you to view heic pictures and convert any number of them to jpeg at one time in several clicks preserving quality and all metadata.
App features:
* Browse and view any folder containing *.heic files.
* Open and view *.heic images.
* Save and share *.heic images in *.jpeg format.
* Batch convert any number of *.heic images preserving quality and metadata.
* Preserve all image metadata like: location, Exif, XMP, Copyright, ICC profile.
* Preserve depth image if presented.
Luma is designed to enable you open and convert to jpeg multiple images with *.HEIC file extension at a time. These are images in High Efficient Image Format (HEIF). Images in this format take twice less space on your device without any loss of image quality. Using this format will help you to save up to 50% of storage space for images.
Luma works completely offline and you don't need to internet connection to make the app working. You can either open single image or select any number of images and convert them to jpeg without loosing quality or metadata.
Hope for your positive feedback and review
The app does not transfer metadata when converting to HEIC. And it does not recognize DNG files as source. Can you please fix that?
Thank you
HEIF and HEIC file association to Luma app by file managers
Congratulations for this very nice Luma app! It enables HEIC file viewing on Holographic 3D phones (RED Hydrogen One and EStar Takee 1) as well as on other autostereoscopic 3D phones (ZTE Axon 7 Max and SuperD D1).
Why is the Luma app invisible to several android file managers (CX File Explorer, X-plore, Total Commander, Files by Google, etc.)?
Is it feasible to enable HEIF and HEIC file association to Luma app by the aforementioned file managers?
Can you do it, please? It will make many people happy.
Regards,
YuriRM

Is there a way to bypass the limitation of 25 mb (5773 x 4330) when exporting an image? Like changing something in the program files?

Hi all, this is my first post here so please be gentle
I recently upgraded to a Galaxy A52 and have been compiling all of my photo collections onto said device. Motion photos (originally taken on an S9, then stored on an A3 2017) worked perfectly fine, and now I'm trying to figure out if I can get Live Photos transferred from my iPhone SE 1st gen and converted into Samsung's Motion Photo format.
I've searched and tried experimenting for hours, but I haven't found any evidence of someone successfully making a native Motion Photo. If anyone has heard of such a tool, I would love to know.
I did find tools to extract them (https://forum.xda-developers.com/t/samsung-motion-photo-extractor.3339997/), as well as some details about the file specs (https://github.com/photoprism/photoprism/issues/439).
A basic technical summary for Samsung's Motion Photos is that there is an mp4 file embedded into the jpeg metadata as binary data.
I tried my hand at making such a tool for converting Live Photos to Motion Photos on my own, using ffmpeg and exiftool. This is the flow I attempted:
1. Use Google Photos to backup Live Photos from my iPhone
2. Download them on my computer, which will give me .jpg and corresponding .mov files
3. use ffmpeg to convert and remux .mov file into correct container and codec
4. use exiftool to merge video file into jpeg file
5. copy to new Samsung phone
Unfortunately, I got stuck on the 4th step in writing the exif tags. the tags that Samsung uses are non-standard, and I couldn't find any clear resources on how I could set up an exiftool config file to do so.
I also tried downloading directly from Google Photos on my destination device, but the downloaded files are not visible outside of the Google Photos app so I cannot examine them or use them with any app other than Google Photos. I tried on a rooted emulator, and I could only find the photo portion of the file (corresponding video was not embedded and nowhere to be found). Even if this did work, it would not be a practical method as from the Google Photos app photos must be downloaded individually (no bulk option)
I've mostly given up on this and am not particularly seeking advice, rather I thought I'd share my findings and attempts as there doesn't seem to be much information for converting Live Photos to Motion Photos. Of course, if someone does know how to properly set up exiftool to write the correct tags into the image file, I will be happy to share the batch script I make to convert my collection.
--edit--
just for reference, I created this https://exiftool.org/forum/index.php?topic=12388.0 corresponding post in the exiftool forums, so if someone finds this in the future trying to attempt the same or similar thing, maybe there will be helpful replies there.
