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.

[Tip] How to change DPI settings on NST

Protip :
tutorial on howto increase Nook's "resolution" by changing /system/build.prop
http://forum.xda-developers.com/showthread.php?t=823522

Can someone do a compare?
I scanned the thread and performed the following actions:
First I used the "test" commands to experiment with settings. I discovered that I liked a density setting of 133 best.
# setprop qemu.sf.lcd_density 133
# busybox killall system_server
So I modified my /system/build.prop by changing the line
#ro.sf.lcd_density=240
to
ro.sf.lcd_density=133
and rebooted.
So, everything is certainly smaller, but as I have only one NST, I cannot determine if I think the text is sharper because I can't do a side-by-side comparison. So, is there somebody out there with two NSTs who is willing to make this change to one of them and then do a side-by-side comparison and report back?

You can do few screenshots and compare them side-by-side.

screenshots?

dude...wtf?
Just type "screenshot android" into your search engine.
I use 'ddms' via adb.
http://www.makeuseof.com/tag/how-to-capture-screenshots-with-your-android-mobile-phone/

No real difference
Here are two screen shots I took. (Thanks for the link osowiecki). The first was taken with the density set to 160 (standard) and the second with it set to 120. There is some difference in the size of the header and footer lines, but I see no real difference in the size of the book text. Setting the density to 120 does allow the standard B&N library app to display nine titles on one screen instead of six. Otherwise I see no difference when using the standard B&N reader.
I did these tests using the LCDDensity app.

Here are screenshots of the library app in each density ...

I can't confirm any changes for text based books, but it definitely helps with converted comics. No idea why the screenshots are green, used "screenshot" tool from within adb shell. Tried with default DPI, 133, 120, and also pulled the image from the unconverted CBR for comparison.

My screenshots taken with the screenshot tool in ADB shell were green also. You will get better results by following the procedure outlined in the link in osowiecki's post.

Was the first thing I tried, couldn't get it to recognize my device. I'm not sure if it's a wired ADB only thing, or a "doesn't work on Linux for some reason" thing or what. ah well, I kind of like the green look

Display Calibration profile

Hi,
Anexed, you will find the calibration profile for our phone. Well, for my phone at least, as you can have a different SP serie with a different display caracteristics. To install the profile on PC, double clic XperiaSP-Sat5.7+Tint50.icc, then it will appear named "latestDisplayProfile" in photoshop.
How I did that:
- First, I set the white balance (in settings) with : Tint=50 and Saturation 5.5. With that, my white point is near 6500K. Also, Bravia engine must be disable.
- Then I used my i1DisplayPro colorimeter with the free X-Rite ColorTrue app. This app is not available on Google Play as it is supposed to work with a few devices. But I was able to download it in a different way and it works on XperiaSP !
What can we do with this display profile:
- If your desktop monitor is calibrated, in photoshop you can simulate how an image will look like on the phone. Usefull for themers.
- In photoshop, you can convert profiled images (srgb or adobeRGB) to this profile. Doing that, you can visualize a photo on the phone as close as possible to the original. It can be usefull for a nice wallpaper.
An other possibility, is using x-rite app to visualize your pictures corrected on the phone. For that:
- installl QuickPic from googleplay, xrite does not works with SemcAlbum.
- download my xrite backup (titanium backup) : https://dl.dropboxusercontent.com/u/32890756/XperiaCalib/TB-XriteCalib.zip
- extract zip and put the 3 files in your titanium backup folder
- restore ColorTRUE using TB
- Launch it: it will say it's not able to found a device (colorimeter) but don't worry. Just click the gallery icon and it will launch QuickPic forcing pictures calibration. You will be able to visualize better your photos.
- Don't forget to disable bravia and set white balance to the same values of mines.
That's it !
[EDIT] Added a color profile for native white point (when you use cm7 or any rom without the white point setting from sony). Using X-rite app you will have to replace overwrite the icc profile in /data/data/org.x-rite*/*icc*/latestDisplayProfile.icc

Thank you. I did the same with my Spyder. So if there are Spyder users out there you can do exactly the same with the SpyderGallery App. Also for free in the Play Store. Works with all Android devices.

Thanks for this information. I have an old spyder3 and never saw that app.
Just missing the possibility on android to load the icc profile ine the gpu driver ... perhaps one day ...

Very good, continue their work and welcome
Muito bom, continue seu trabalho e seja bem vindo!

native white point icc profile added.

Hi!
Sorry for posting my message to this topic. I have Sony XPeria Z1 compact, not Xperia SP. But there are not so much people interested in making color profiles for their phones. So I hope you can help me here.
I have calibrated my phone display with ColorTrue. And I can watch my photos in QuickPic using ColorTrue. But the thing is that photos open very slowly when using ColorTrue. So I'd like to convert my photos to this profile in Photoshop. But I can not find *.icc file. I have only this:
/storage/emulated/0/xrite/iccprofiles/profileData.xml
Can anyone help me to get ICC-profile for my phone?

You need a root explorer and then you can pick up the profile in /data/data/com.xrite.mobile*/*icc*/latestDisplayProfile.icc

epd_optimizer recommendations thread

So Marshmallow uses this new format for configuration files for apps on the EPD. Maybe we can start collecting recommended configurations for various apps? I noticed that the default files it comes with don't include the Kindle app this time, tho it had a default config in the old LP settings.
So, if you've found good settings for a particular app, please post them here! And I might go look on the Russian site to see if there are any there already - tho if one of the Russian-speaking users here wants to do that first I wouldn't complain
edit: I just found an app for editing the new configuration files, it's by x2009xxx on this hi-pda thread. Attaching for convenience. The button at the bottom to save the configuration and the toast that pops up when you do so aren't in English, but all the options are, so I'm pretty sure you can figure it out. (Don't forget to reboot to activate your changes)

I am wondering is there possibility to set epd to full refresh after 5 pages or every page. There is no sign in readme file. I tried adding ""slowmode" : true" in the configuration cfg but notting happens.

I'm not sure, but I have gathered that you have to reboot for changes to take effect.
Sent from my YD201 using Tapatalk

I know, when I change something (ex. dithering, sharpening etc.) there is effect but problem is that i don't see command which can set full refresh of epd screen after some interval (previously it was slowmode). I'm using moon+ reader (white letters on black background) and without full refreshing after some pages ghosting is terrific and reading seems to be nearly impossible.

Remove the Android GUI transitions/effects on Developers Menu, not only makes your phone faster but it also helps EPD to have less ghost when using the other Android Apps, and folders...

I just edited the first post to add a tool I found for editing the config files.

I'm looking at the readme.txt that lives in the epd_optimizer directory, and the option that sounds related to what you're talking about is "update_timeout - timeout of fullscreen update after content change. Use -1 to disable."

Tried to change update_timeout value. There are some changes in update mode but EPD still not doing full refresh (like in Yotareader for example). Still after flipping some pages black background is full of gray shades from previously viewed pages. Tested on CoolReader, Moon+ FBreader, Allreader.
Is there anyone who figured out how to set full refresh of EPD in any book reader?

Nice thread, I had in mind creating one like this. I haven't played with the configuration file yet, but I can post here what I found from other xda posts and a file from Russian Telegram group.
For Whatsapp (but I think it should work also on other similar apps) a configuration found here is the following:
Code:
{
"name": "com.whatsapp",
"description": "WhatsApp",
"dithering": "ATKINSON_BINARY",
"update_timeout": -1,
"sharpening": 2,
"contrast": 0,
"brightness": -5,
"stretch_black": 50,
"stretch_white": 220,
"regional_update": false
}
For Vkontakte (VK - Russian social network) I found this one:
Code:
{
"name": "com.vkontakte.android",
"description": "VKontakte",
"update_type": "GRAYSCALE",
"dithering": "ATKINSON_BINARY",
"update_timeout": 0,
"sharpening": 1.0,
"contrast": 50,
"brightness": 10,
"stretch_black": 50,
"stretch_white": 200,
"regional_update": true
}
Maybe we could develop some configurations for groups of apps: chat, social, e-book readers, office, browser, etc. and post them here!

Don't know if I'm missing something but I've tried all sorts of different values for dithering, update type, contrast, brightness, stretch_black, and stretch_white but after restarting nothing seems to have any effect. No matter what I do, everything just looks way too bright/low contrast and washed out. On the other hand, the Yotahub looks fine--deep blacks and easy to read.
This is on a YD206. Everything looked fine on lollipop. I submitted bug reports to yotadevices but they told me that the YD206 isn't supported. Anyone else having this issue? And if so, are you on YD206?
EDIT: Anyone know how to query what epd_optimizer settings an application is using? The backscreen is the only thing that looks good and AFAIK its package name is com.yotadevices.yotaphone2.launcherbs . Unfortunately there's no corresponding entry in the epd_optimizer directory.

Here is a stock EPD_optimizer folder after OTA upgrade from 5.0. Try replacing your files and reboot.
I figured out that changing values via application make a mess in cfg files. Better to check package name using app, copy some stock cfg, rename it to package name and edit via Total Commander it works fine.
I have yd206 and changing values take effect but i can't set full EPD refresh.

From readme.txt
If these parameters are missing in app's configuration as well, the system will use parameters which defined in master.cfg configuration file. If this file is deleted, the system will use parameters that are stored within Android framework.

Thanks, I'm no longer using the app to modify the values as you suggested and changing settings has an effect now. (using vim in an arch chroot environment) Using your stock values for a separate firefox config seems to have improved things. Still not nearly as good as 5.0 but I can actually read text now.
However, there is this issue where from moment to moment the screen brightness seems to switch back and forth between two settings: a config with deeper blacks (clear) and a config that's too bright. It's almost as if there are two configs fighting for control. If I let the phone sit (so there are no screen updates), it will eventually settle on one of those configs but not reliably on any particular one--it almost seems random. I spent several hours trying a variety of different settings but I can't seem to get rid of this problem or manage a config that's comparable to 5.0.
At this point I think I'm just going back to 5.0 as I can't really put any more time into this. Maybe the problem will sort itself out in future releases but I'm not hopeful given the lack of support for the YD206.

I have three yd206, one which firmware was sideloaded from 1.1.31 had simmilar to your EPD glitchs, try to delete your epd_optimizer folder, create new one and copy files from attachment, then do a hard reset. It helped me and now this yd206 runs flawlessly.

I found the file /root/sdcard/TitaniumManager/mirror.cfg has some information similar to files in .../android/epd_optimizer and create a configuration for FBReader, but makins some test it seems nothing change.
Follow the last solution for my file org.geometerplus.zlibrary.ui.android.cfg
{
"name": "org.geometerplus.zlibrary.ui.android",
"description": "FBReader",
"dithering": "ATKINSON_BINARY",
"update_timeout": -1,
"sharpening": 1.0,
"contrast": 70,
"brightness": -10,
"stretch_black": 50,
"stretch_white": 220,
"regional_update": false
}
Have you any suggestion?

Hi, couldn't get this off of my mind so I took another stab at it. I've tried everything you've suggested but haven't been able to get things to an acceptable level. I've put together a couple images comparing 5.0 and 6.0 image quality (attached to this post) with the epd_optimizer .cfgs you've provided.
The two images have a few different icons on the home screen but demonstrate the difference in both brightness and clarity pretty well. I'm not saying those .cfgs didn't improve things--they definitely did (yes, it originally looked even worse than the 6.0.jpg image prior to using the .cfgs you provided) but it still doesn't look nearly as good. Looking at the 6.0.jpg image, you can probably imagine how difficult it would be to read an ebook or browse the web.
I think there's more to this than the .cfg files. Note that I upgraded to 6.0 by restoring the "MMB29M.6.0.1-RU1.1.147" backup provided in this thread via TWRP. I was coming from LRX21M.5.0.0-HK1.1.124d (I always clear the cache and dalvik between firmware changes of course).
EDIT: Whoops, I've mixed up the image names. Fixed the images.

Excuse me i do not know about changing that values for the epd
but as a person who works and edits photos the difference between the pics is remarkable in my eyes
beacuse it seems to be that there are different grey scales that are produced, especially the black value.
You can edit every photo you made into greyscale (8bit or 16bit) and it normally looks fine.
but you can also convert it into a black/white (1bit) picture with a filter like diffusion and it is more grainy.
so for me it looks that the 6.0jpg is too grainy and is not the correct grayscale. It can be washed out but the black part seems not that fine as it is in the 5.0jpg pic.
maybe this isn't that important but i want to point on that.

My navigation program has the same probem. Too much ghosting. Is there a possibility, to set a refresh time? (Maybe a background program with timer and torch screen?) I can do it with developer options (show surface updates). Is it possible, to make a shortcut or start and stop it automatically?
If the yotaphone is in standby, the epd screen is constantly flashing (after 2 minutes) and I don't know, why.

I am experiencing the same. I own a YD206 converted to 201 and running lates MM OTA update.
EPD screen was fine for couple of days, but know ghosting is terrible specially when navigating thru full Android. Also black color on widgets is totally grayed out.
Right now I am trying the full discharge and leave it for couple of hours before I fully charge it.
Any other solution/suggestion on what to try? This is definetly a refresh problem which is not eliminating previous images.
Thanks

NST Screen Saver Frequency Setting?

I've successfully rooter my Nook Simple Touch and explored all of its files and databases that I can find. But I cannot locate the setting to change that will update the frequency at which the screen saver changes images.
My goal is to have a folder of image files that change every 30 seconds or so. Unfortunately, the stock screen saver's change timer is much longer than that.
As a workaround, I set the screen saver activation time to 500 hours and installed Perfect Viewer to run its slideshow function, but this is less than ideal. I'd rather just do it the right way.
Does anyone know where this setting is located?
Thanks!

OK, so I have to admit I didn't even know this happened. It's been a long time since I used a folder of images for a screensaver. What I seem to recall from that time was the images changing each time the NST went to sleep, but not during sleep.
Let me take a look. I guess one possible approach would be to consult a logcat after an image change and see if there are clues there.

I've come up empty on a search through the various B&N app databases and settings files.
Just to see this actually happen, I changed my screensaver from a static book cover image to one of the packages of images I installed years back. That was nearly 24 hours ago and there is still no change, which is what my memory told me to expect. So without an automatic change, there is nothing to look at in the logcat.
Are you sure your images actually change by themselves during the standby/sleep process? I know they change when you wake up the device and then let it fall asleep again.
You've already tried the slideshow idea or I would suggest that, but did you know there is a built-in slideshow (probably associated with the demo mode)? I don't know what the parameters of that are or whether you could replace the images with your own without breaking it.
Maybe a better question to help me understand what you'd like to do is: will the NST be used for something other than the slideshow display (either running in the background or running on demand when the device is awakened)? If all you want is the slideshow then any number of apps (like the PerfectViewer you mention) would work. Maybe something simple if you just need the slideshow. But if you really are using the device for other things and just want the sleep screen to change periodically, that's either got to be supported in the settings in an accessible way (which I'm doubtful about) or it has to be a custom alteration of the OS.
