[Q] Hacking camera resolutions - Galaxy S 4 Q&A, Help & Troubleshooting

Hi there.
I came from a previous HTC Inspire 4G phone. After a lot of custom rooms I ended up with one that had a lot of camera resolutions available for "hacking" the camera.
I'm wondering if there's a hack, code or something that can be changed on the S4 in order to get more camera resolutions.
What I'm trying to do is actually getting lower resolutions, like 640x480 or 1024x768 so I can take "snapshots" and avoid post-editing of the pictures.
To illustrate exactly the problem, I use the camera phone to scan big documents into pdf. Now the higher resolution of the default camera makes imposible to handle +30 pages scans, and the workaround (taking the picture, open the picture with a photo editor, resize the picture and save, then import picture on pdf scanner app) is not good enough, as it would steal the valuable time that you are suppose to be saving with this phone.
On the HTC the lower resolutions made it possible to just take a lot of "low res" pictures and pdf them really fast directly within the application.
I'm guessing that if you could pre-define lower resolutions to be selectable already on the stock camera application, maybe adding another ones could be as easy as "typing them" on the respective configuration file for the camera.
Any ideas?

Perhaps just take normal sized pictures at the nearest resolution and then write a bash script to crop or resize as necessary, and import that into the scanner app?
I'm not familiar with any hacks available to go beyond the usual stuff.

You can use InfraView (freeware) to batch resize all images. I do it for scaling boot animations all the time.

photographer's app?

I am looking for an app to assist with medium/large format photography. Currently I use a spreadsheet to note the various settings for each frame, however there was an app (photoassist) I used on my old WM5 device that had drop down menus, though it doesn't work on the TP2.
Something that can also use the phone's camera as a lightmeter would be great too.

I second that I would love to not buy another Gossen Digipro F I would even through a $100 bounty on this. That will still save me $170.
Resco Photo Viewer can handle .raw, .tiff, .png, etc... files. Spb Imageer can do the same.
However, large format photos are going to cause extreme issues. The OS has a memory limitation of 32MB, so anything approaching that size will cause your device to crash...
Could you perhaps elaborate on a feature set you're looking for in this application? If I understand correctly you're wanting a way to record information about your individual frame settings, not a way to view or arrange these images on your device, correct?
I'm not promising anything, but depending on your requirements I might be able to assist you in creating an application that suits your needs.

Yes, it would be a pretty simple app. Basically there would be multiple drop down fields that are prepopulated with different values based the prior selection, some thing like-
Film size- 120/220/4x5/8x10, then presuming 120 is selected, brings up the next field,
Image format- 6x6/6x7/6x9/6x17, then presuming 6x6 is selected, brings up
Film type- Negative/Color Reversal/B&W, then
ISO- 50/100/160/200/etc, and so forth.
The above would be "master fields" that are global to the film I select, and subfields would then include the frame #, aperture, shutter speed, EV, etc.
All the info would then be recorded into a spreadsheet or database for later viewing.
The side app to turn the phone's camera into a lightmeter would be as simply as providing a live output of EV (exposure value) based on what the camera is seeing. A plus would be if it could output ISO/shutter speed/aperture values too, but we'll take things one at a time.

[Q] How to fix screen resolution?

Hi everyone, this is my first post, I'm not sure if it's been posted yet. I'm a photographer and I do not use the camera on my HD2 because I just import my photos to the phone so I can display samples of my work to potential clients. The sharpness of my photos when displayed on the device was the main driving point for me purchasing this phone. One thing I noticed however, since flashing my photo to Windows Phone 7, my pictures are not sharp at all anymore. I just loaded a picture on to my friend's WinMo 6.5 HD2, and there is a drastic difference. I've seen posts about the camera taking blurry pictures, but I haven't seen any that just indicated general blurriness on the screen. Is there a fix for this or will I have to give up my WP7?
That's odd, my transferred pix are excellent, maybe you should reload WP7? Not much help I'm sorry but it doesn't take long to reinstall...
what res are the pictures?
I had the same problem but it seemed to only happen with photos that I transferred to the phone. I never found a fix, though I do not think it is a resolution problem with WP7. The issue might exist in the file transfer itself; perhaps a Zune issue? Anyway, I never found a solution so I'm back on 6.5.
Try this:
In the Zune software, go to
Settings > Phone > Pictures and Video
and set "Image Quality" to "Original"
I tried the settings in Zune and those settings were already selected. The resolution is 3744 x 5616, but it doesn't matter the photo size, they all still aren't crisp as they were before.
try changing them to 1024x1024, maybe wp7 is lowering them automatically because of how large they are
even the ones i had at 950 are blurry, no matter what photo I load into it...same result.
**Update**
Since my last post, I have flashed back to 6.5, loaded some photos on. Image resolution is far superior. Loaded WP7 back on, [a different ROM], and still photos are still not a sharp. Is it possible that the photos do not render as well in WP7 as they did in 6.5?
strange, i use both zune for pc and windows phone connector for mac to transfer my 12mp photos from my cannon450d and they are reasonably sharp for a screen with limited pixels.
Even my photos from facebook look reasonably good (not much difference on the small screen to be honest)
Yeah for me, whether it's from my Canon 5D Mark II, or my 50D, same problem. At this point, I just won't load any photos on the device! It sucks because my main reason for purchasing this phone was photos, and also that ability to put different ROMS on it.

Email a photo to yourself, and save it on the phone. See it works that way.
It may be that the stock wp7 picture viewer doesn't display them as sharp. Maybe you can find another photo viewing app in app store and see if that makes any difference.

[Q] Saving the Zoom Level/position in an image Gallery for certain pictures

Hey guys,
I don't know if this has been requested before (cause it is pretty hard to describe the problem, therefore the search didn't really get me any answers) some of the users here in germany would really like to have a gallery, where you can save on which level and where you zoomed in into a picture.
For example, if you are sliding through all your photos etc. and you see something special so you zoom in, you wanna save that zoom level / Position for the next time whenever you view that picture.
The device we are talking about is an Asus Eee Pad transformer but I think other tablets would benefit from this feature as well as you tend to zoom in on 10 inch screens a lot to see all of the details e.g. of the pictures which were taken with a Canon/Nikon Camera.
So is there anyway to achieve this with already existing image viewers or could anyone implement it into an existing app?
Greetings

Wallpaper Aliasing and Compression. How to stop this?

I've been taking some 3840x2160 screenshots on my PC and transferring them to my phone uncompressed. They look really good when i look at them on screen through the gallery: Nice detail, sharp lines etc.
The images are taken in portrait so that when I download them onto my phone, I can rotate them 90 degrees so they fit the screen properly.
The problem is when I go to set the image as a wallpaper, the image becomes compressed ever so slightly. The once smooth lines are now noticeably jagged, even though there seems to be no stretching or scaling of the image. I am able to zoom in to the image to the exact same scale in the gallery and everything seems fine.
To me, there must some kind of process that is converting the image to a lower resolution or compressing the image in some way. My question is how do I stop it so the wallpaper looks nice and sharp.
Anyone know what is going on here who can tell me how I can prevent this?

You've answered this yourself.
Your image is 2160p
The screen is 1440p
Or 1080p if like me you've realised that's m that it's virtually impossible to tell the difference and it's a negligible visual benefit for a significant battery hit.
So resize the image based on the screen you want to use or the phone will do it for you.
Depending on the launcher you're using you it may actually have a size limit and resolution so there should be they to take into account too.
Start by finding out what resolution you're using then get an image for it off the same resolution

I did some additional research into the issue.
The oneplus 8 pro is 3168x1440. It is perfectly capable of displaying a 3840x2160 image with no significant loss of quality. I was able to zoom the image in the photo gallery to cover the entire display (as a wallpaper would) and found the image still looked crisp as it should, yet setting it as a wallpaper caused quality loss despite scaling the same. Clearly the issue was to do with the wallpaper scaling process in android (what the exact issue is i am not sure).
Nevertheless, i downloaded an app from the playstore that was able to fix the issue. The app is called Image 2 Wallpaper on the playstore.
