Pureview 808 - Need constant screen brightness: Ho...

On the Nokia 808, even though the screen brightness is set to a predefined brightness and Power Saving mode is Off, the screen brightness can change at times.  The time limit for the backlight is set at 60 seconds, but the LCD screen can dim a bit within that time.  My guess is the brightness changes in response to ambient light changes.
Its hard to adjust exposure compensation and evaluate photos for proper exposure when the LCD screen brightness changes on me.
Anyone know how to keep the LCD display brightness constant?
Thanks in advance,
Keith.

Wow, thank you very much!  By downloading the "Brightness" app, the screen brightness is now constant!
Now I'm able to get a handle on how much exposure compensation to use since the display isn't a variable anymore.
Also it appears that I'm not losing images when shooting in burst mode anymore.  Perhaps the change in screen brightness operation led to corrumption while the image was being saved.  Before the Brightness app, 1 out of 3 images in a burst would almost always be lost.  Its too early to know for sure.  Only time will tell if the corruption problem has been completely mitigated as  a byproduct of using the Brightness app.
Thanks again,
Keith.

  • OS change in Pureview 808

    Nokia Pureview 808 currently running on Belle FP2 which lacks in running modern apps like Skype, Nimbuzz, Whatsapp etc. The browser on Pureview 808 is not at all good compared to IE on WP8. These apps works fine on WP8. Hence W8 for Pureview 808 needs to be released, because Pureview 808 is the best phone ever and stays behind in the race only because of Belle OS.
    Solved!
    Go to Solution.

    I was hoping for that until the Lumia 1020 came out with an arguably slightly less awesome camera hardware, but greater photographic software. Sad but true, I'm going to ditch my Symbian-classic 808 PureView out of the blue for a Lumia 1020 because 808's development has been stopped and L1020 can do much more, especially with creative gadgets provided by Nokia such as wireless chargers--I have to admit that and swallow my pride of my 808 in order to invest in a foreseeable future of Nokia Windows phones.

  • Screen brightness on 808 - after timeout even brig...

    Hello,
    I have set my screen (backlight) brightness on 808 Belle FP2 to minimal possible (and in the night it's still too much imho).
    I have set the display timeout to 5s (minimum). However, after this timeout, the screen gets brighter instead of turning backlight off or at least keeping it minimal.
    Is this a known bug? Can I do somethign with it?

    Hi fantomas,
    I can confirm this bug. With the great app "Situations" I have created a "night" situation on my 808 (FP 2) where the phone goes into powersaving mode. There, the lowest screen brightness is chosen. Sometimes, a few seconds after the last touch on the screen, it becomes brighter. Touching the screen again makes it go back to the correct (=lowest) brightness level.
    It shouldn't be too hard for the ex-Nokia emploxees at Accenture to fix that.

  • [Solved] Screen brightness control issue

    I just purchased a Lenovo T410s. I have set it up to only use Nvidia and only give visibility to the Nvidia GPU. The problem I have is once X starts I can no longer change the screen brightness with the function keys. I'm using KDE and it registers that I'm trying to change the brightness but the screen never changes. If switch to run level 3 I can use the function keys to change the brightness without an issue. I'm confused at what is causing the issue. I'm not sure what information you need to help me, but I will give you what you need if you tell me.
    EDIT: I discovered on the Nvidia forums that the backlight function was disabled in the drivers for this model. Apparently when in use it causes squealing sounds.

    I did some more testing and here is what I found out. I switched my laptop to use integrated GPU only, so that means Arch sees my GPU as the Intel HD. Now I can boot X and control my brightness with the functions keys. Has anyone else run into the problem with Nvidia drivers and the Quatro NVS 3100m GPU?

  • How adjust screen brightness in Windows 7?

    I used to use a Windows 98 laptop up to 3+ years ago, but since moving to Mac have largely forgotten how Windows works. I now have Windows 7 on Bootcamp and can't see how to adjust screen brightness. Surely there should be an adjuster on the System Tray (that's what it used to be called) bottom right next to the clock. I'm on 20" iMac with Apple keyboard (the long one with number pad at the right).

    Does the keyboard have brightness controls on the F keys?
    If these do not work: try holding fn and using the F keys.
    If that does now work I have to ask: have you installed the bootcamp software? you need to make a CD (or usb stick) of drivers and software from OSX then boot into wiondows and run it.

  • Camera problems with PureView 808

    Ok, i saw a lot of people on the internet forums talking about the black picture problems, so i wanted to make a clear statement for the people in the developing center, and ask them to fix these issues asap, thus avoiding a serious humiliation...
    So, the problem is most obvious when trying to make photos in bracketing(HDR) mode: at first i started experimenting with just normal settings, exposure compensation set at 0, ISO 50, bracketing mode: 3 images -2/+2. i shot a few pics indoors, and then in the open, when i started noticing the first two pictures have exactly the same exposure comp, and only the third one is actually with +2EV. OK, this problem you can sometimes (not always) solve by reseting the iso value back to auto, and then again back to the desired value(usually 50 or 100), BUT when you set the starting exposure compensation at something lower than 0 (i tried with -2 most of the times) it is inevitable getting first two pictures having the same exposure compensation, and sometimes even first two pictures being completely dark/black, and no, this is not supposed to happen with these settings, not even with -5 exp comp, and 50 ISO.
    The next problem is similar to this one: when in creative mode, normal setting(still image), sometimes what you get when not putting ISO setting to AUTO is, again, completely dark pic, you dont even have to put ISO sensitivity to a high number (which is against logic: high ISO number would mean brighter image), as some people on the forums have said, but you can put it to 50 (the one I use the most) and again get the completely black picture. Resetting the ISO to auto and back to desired value again helps in this occation...
    And the last conplainment from me for now(camerawise): SOMETIMES chaning the exposure compensation (in real time) on the slider (on touchscreen) doesnt actually do anything, viewfinder is showing the exact same picture on the display, and histogram is not showing any changes.
    HOWEVER, there is an app i downloaded called CameraPro, which doesnt have any of these problems at all!!! It works perfectly well, but the problem is the user interface, there is no option for saving your own preset, as in original factory camera app on the PureView 808 (C1, C2, and C3 in creative mode), so it takes a lot of precious time making the best setting possible (avoiding the auto mode). 
    PLEASE NOKIA, or anyone competent enough give me solution for this(software update with bug fix) 

    Suggest you look here http://onlyfoolsandmobiles.com/  and Here http://pureviewclub.com/ both full of good advice , tips and tricks, the things you require are demonstrated on both sites, I am not a camera expert, but think some of the settings you are trying are causing the issues you have, do a little research, the 808 is capable of doing everything you want and more

  • 24" iMac Screen Brightness Bug and others

    Hi,
    There seems to be some serious issues with the 24" iMac. About 6 days ago I bought a 24" iMac (2.66 Mhz model w/4 GB RAM + 640HD).
    Out of the box it had Leopard 10.5.5 installed; there were several problems.
    1. Screen brightness was way too BRIGHT. Display preferences would not pull brightness down. At least not down far enough so that the screen could be viewed without extreme discomfort. Plus add insult to injury a reboot would reset the preferences to maximum brightness. NOTE: An upgrade to 10.6.1 did NOT fix the issue.
    2. Viewing a browser page via either Safari or Firefox (latest versions of each) was not good. A vertical scrolling would be jumpy and appear pixelated. Upgrade to 10.6.1 seemed to fix most of the issue in Safari, but Firefox was still not working properly. The issue appeared like a horizontal "ripple" in about the bottom 2/3 of the browser window. The effect did NOT extend outside of browser window. Changing screen resolutions did not work.
    3. Connecting a USB Logitech head set caused issues with Sound preferences.
    If the head set was connected during startup the machine would recognize them as main sound. The internals speakers did NOT appear in the Sound preferences. as an optional choice. Removing USB headset and reboot would return the internal speakers to the Sound preferences. Plugging in headseat would work for a while. We could repeat and same problem would occur.
    These are all in 10.6.1 - definate bugs.
    Returned with the iMac to the Apple store. Bottom line, after nearly three hours; the Apple technician, and everyone could see what we were talking about.
    Regarding the screen brightness. Nothing they could do about it. They stated that "not too many people have complained about it, to their knowledge." They stated that the electronics in the "florescent" panel could not be turned down the same way. TRANSLATION: The programers at Apple let this one slip past them. As a customer (software programmer & network analyst) I expected a bit more of an intelligent answer.
    However.
    Examining the 20" model I noticed that we could turn down the screen brightness - at least to a level that my wife and I could live with. PLUS the settings remained after a restart. Something that was NOT happening with the 24" model.
    So - we exchanged the 24" for a 20". Frankly we are a LOT happier. The Safari/Firefox issue is still carried over to the 20". However it is not nearly so noticable on the smaller screen.
    Plus the USB headset did not cause the same Sound Preference issues.
    So - Thanks for the speedy return/exchange of the iMac. But someone needs to look at this from the programming side of things.

    HI, in response to 1_pixelperson, we've returned TWO iMacs with 24 inch screens, both so bright our eyes bugged out ... the current 20 inch is our third computer in 8 days ... he reported specifics
    We did find a SCREEN DIMMER app <www.adpartnership.net/DarkAdapted/> ... no solution via Apple ... iPhoto migration funky, dates out of sync, not valid, but thankfully Time Machine really works ... Firefox remains wobbly, not smooth ...
    Also, be careful when loading pics from phone with Bluetooth, it sucked my entire address book into my phone.
    People at Apple store were nice, today's 20 minute scheduled Genius meeting morphed into two hours+ ... including return ... would have preferred 20 inch with larger HD, came with 320 ... they couldn't do, upgraded ram while there.

    I have the popup omn the screen from the keyboard shortcut, but nothing haoppens. its on full brightness.
    Left click the battery icon in the tray and there is a place for 'Adjust Screen Brightness'. It takes me to a page 'Select A Power Plan' where it SHOULD be but doesn't show up. If I select 'Change Plan Settings' it is there but has no effect. its all still full bright.
    It was working fine until the malware.
    Did sfc /scannow, nothing to report.
    Any ideas on this?

    Hi @fjward ,
    Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue HP ENVY 17-3090nr 3D Edition Notebook PC and issues with brightness control and the Catalyst Control Center.  I would uninstall any graphic drivers that are listed and  CCC software, restart the computer, then reinstall only the AMD. It will include the Amd Graphics Driver and Catalyst Control Center restart the computer.
    Here is a link to the HP Support Assistant if you need it. Just download and run the application and it will help with the software and drivers on your system.
    You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook.
    When performing a System restore please note remove any and all USB devices. Disconnect all non-essential devices as they can cause issues.
    Please let me know how this goes.
    Thanks.

  • How do I make screen brighter and the sound quality better with W8 OS on my iMac through bootcamp assistant like it is with my mac os ?

    How do I fix my screen brightness on my imac  via W8 OS on my Imac through boot camp assistant and How do I fix the quality of the sound coming from my imac when in w8?

    Alright, first off, thank you for your help so far. I really appreciate it. However, now I have a new problem that I need help with.
    I did exactly what you've said to do, and it worked fine, the screen itself became brighter again, it was just too dim before and the brightness settings were all the way up, but after doing what you said to do, It's as it is when using my Apple/Mac OS. The sound coming from the computer speakers and all the other audio issues have been fixed as well. It all sounds like it should in terms of quality. It's just now that I did that, I'll shutdown my computer, or even restart it for some reason, and each and every single time I do that, It's all back to the way it was before installing anything, dim and poor audio quality. Until I install the drivers again like before.
    Am I going to have to get used to that or something? Or is there an option I'm just not seeing that would make these preferences and instalations permanent until I input/imply otherwise??
    Thanks in advance!!

  • Adjust Screen Brightness Satellite Pro 4200

    Hello,
    i heard from a combination of keys which makes adjusting the screen brightness possible.
    Is that true and what is the key-combination?
    Yours sincerely
    Riedlz

    Hello
    Nicky is absolutely right but as far as I know all Toshiba notebooks have the same keyboard and all have the same key combination for brightness changing. Your Satellite Pro is pretty old and at this time maybe it was a little different.
    Like Nicky already said check the Users manuals or you can download one if you need it.

  • Screen brightness to 1 bar after wakeup after sleep!!

    Has anyone experienced that when you wake your macbook up after sleep the screen brightness is set to 1 bar...
    dont know if this is actually a problem or if it can be set in system pref..
    thanks in advance for your replies...

    Have you tried toggling on and off the automatic adjustment for ambient light? Try checking and unchecking it's box, System preferences>Display>uncheck box. This should keep the brightness of the display constant.

  • 6280 screen brightness

    My 6280 works o/k except for this abnormal (I think) behaviour.
    When a key is pressed or the slide is opened, from keylock, the sreen goes very bright for about one second and then the brightness lowers to the normal level.
    Is there anything I can doabout this as I need to wait for the screen brightness to drop to normal brightness before I can read it?
    Thanks

  • Simulating a screen brightness control

    I am trying to simulate a screen brightness control on a training tool for locomotive driver console. This console has 8 function buttons, which are used to navigate to various screens depending on the scrren currently displayed. There is another button that is used to control the brightness of the display and I want to simulate this by pressing the button and displaying a semi transparent rectangle over the screen. I can do it for a single screen using the advanced actions but I don't know how to have this work on all screens without repeating the process for every slide. I tried to put this feature in the Master sldie but with no joy
    I have an image of the device front panel on a Master slide and I am have created moveable buttons on each subsequent slide to navigate to the relevant images I am navigating through.
    If anyone has any helpful hints on how to achieve this I would appreciate it.
    Cheers
    Greg

    Hi Greg,
    I felt sad when you mentioned the version 5, had hoped you were at least at 5.5. My idea was to create the 'dimming' rectangle on the first slide
      and time it for the rest of the project. The option 'always on top' should be checked. In 5.5 and 6 it is possible to show/hide that rectangle on all the slides, but in 5.0 you can only hide the rectangle on other slides than the first where it really is. This was a less known improvement on 5.5 due to my begging to the engineers. That way you could create one advanced action to be attached to all the buttons, without any editing because the rectangle always had the same ID. 
    In CP6 it would be even easier: a shape button has all the functionalities of a normal button but can be also be timed for the rest of the project: only one shape button with one advanced action would have been needed. Have a look at this blog post: http://lilybiri.posterous.com/why-i-like-shape-buttons-captivate-6
    The idea was to make that rectangle initially invisible, and show it when the button to dim was pressed with an (advanced) action. Now I can only offer some tips to make the cumbersome process of editing shorter, you'll need a rectangle on each slide, and will have to edit the advanced action for each button to point to the correct rectangle:
    create rectangle and button, with its advanced action for the first slide (and test it) before copying both at once to all the other slides
    label first the button and have the number of the slide in the label (like Bt_x where x=slide number)
    it is possible then to use the same name for the advanced action to be triggered by the button
    before copying: if those rectangles are the only ones, you can keep the default names for them
    the copied buttons will get their proper ID, I would relabel them on the slide, go then to the advanced action, duplicate and edit it
    So sorry,
    Lilybiri

  • Change Screen Brightness

    Is there any way to adjust the brightness of the screen in Adobe Air for Desktop (running in Windows 8.1)?
    I have an app that I want to always run at full screen brightness.
    If not, does anyone know of any ANEs that will work?
    If also not, does anyone know where to find a tutorial on making ANEs?

    I you not familar with Native Extensions and C++ / C - you can try avoid using it using already done external apps. Just find one that can work in background so users will not see it.
    http://www.nelsonpires.com/software/dimmer/ go there and download simple app.
    Using executing NativeProcess you can run it. But before you can edit Opacity value in XML. So scheme may be next:
    1) using adobe air edit xml and update opacity value
    2) attach listener to main app exit so when you close it - you also must termiate your Dimmer
    3) run Dimmer with NativeProcess API from Adobe Air
    4) when you exit from main app - listener from step 2 will fire and you must close Dimmer from step using exit() method
    This app actually not reduce brightness and just add black overlay with opacity. In most cases it's work prefectly. When you need to terminate external NativeProcess just call exit()
    You may note that if you have some external app that can cover your functionality - better to use it instead developing own DLL Because Developing DLLs require addition skills.

  • Can't adjust screen brightness.

    On my Tecra R840-S830, I recently reinstalled Windows 7 64 bit and I thought I installed the drivers I needed. My flashcard functions are working perfectly except that FN-F6 and FN-F7 will not adjust the screen brightness. I can also find no other way to adjust the brightness-It doesn't appear in power options or display settings. Any ideas? Am I missing a specific driver?

    Tecra R840-S830
    Maybe this one?
    Tecra R840-S8430
    Instead of struggling to get the install order correct, you should restore the hard disk to its original out-of-the-box contents using Toshiba recovery media.
