My T2i has a turn to blue which can be corrected in photoshop. No cause. How can it be solved?

Just came out not the case. He could have progressive but not sure. The camera was droped two days before it happened. Nithing else wrong with the camera. I learned that it is the sensor or the Board of Directors. But not sure, it can be a solid state board running whether or not.

Any suggestions on how to solve this problem. A $ 200 repair bill appears on top because I could live with it if need be

Thanks for your suggestions

See you soon

Thanks for the suggestion, I now see what you were referring to. The camera has been set to fluorescence (4200K) no AWB. Daylight is 5000 k and 3200K tungsten. The 4200 k is enough to provide a shift towards blue, especially in the shadows (which I think is supposed to be fixed at 7000 k?

Also did you recommned AWB vs manual adjustment for each situation. I'm curious to know how the AWB knows that he is shooting in the shade or inside.

Thank you

I've always used AWB, but I only shoot in RAW mode and therefore allows you to set the color later if necessary. As far as I KNOW, the camera just looks at the temperature of the overall color of the scene and chooses its WB setting accordingly. Better cameras do a better job, but all of them get it pretty close to most of the time. The only possible downside to AWB is that whenever you make an adjustment in post processing, you are subtracting light, so there is good chance that you will have to present to the brightness. So if you know that you only use a particular type of light and that you do not trust the camera to do the things, manual adjustment of the World Bank could give you better exposure.

BTW, in the light of day Canonland is 5200K, but you are right that the tungsten is 3200. (My own experience, however, is that tungsten light may extend down as low as 2500K.) I don't think setting 'fluorescent white' Canon has a temperature of colors defined. It is biased to correct an imbalance in the fluorescent white majority that leaves images with a color cast. (I think it's either pink or green.) So it's a wrong setting to choose manually unless you are sure of your light source.

    I got a virus, got everyting back, except the Start Menu option to turn off. What can I do to recover the option stop?

    Here is some useful information to frequent contributor on these forums Jose Ibarra (slightly modified):

    If you see things like this:

    You do not have sufficient security privileges to restore your system.
    The System Restore tab is missing from the my computer properties.
    System Restore has been disabled by group policy.  To turn on system restore, contact your domain administrator.
    The System Restore tab is available, but the turn off System Restore (disabled by Group Policy) box is grayed out.

    The registry editor has been disabled by group policy.
    The command prompt has been disabled by your administrator.  Press a key to continue...

    Unless you have disabled these things on purpose, chances are good that your system has a malware infection.  The malware knows what tools you use to try to find and remove, for the malware disables the things you are more likely to consume and prevents them from running if you can't find the malware and remove it.

    If your system has this kind of affliction, all malicious software tools you currently use or have used failed to protect your system so that you can expand your horizons malware detection and prevention to prevent these kinds of afflictions in the first place.

    No matter what kind of malware you've used analytical tools, they are unlikely to solve this problem, because they cannot tell if the changes made to your system have been on purpose (you or an administrator who makes them) or some malware changed them, so the analysis tools will let these things alone (it's usually a good thing).

    If your system is afflicted in this way, there are probably other things that also do not work - like the registry editor, System Restore and the command prompt, so fix them all at once even if you have not discovered they are broken again.

    These commands from registry removes the registry entries that are stop opening programs.  Although the registry entries do not exist, these commands are safe to run and will work for all versions of XP.

    [At least in earlier versions of the registry editor, it was necessary to have a blank line at the end of the file (an extra press of the "Enter" key).  I don't know if this is still necessary, but put it in any case. It won't hurt.]

  • Vista has stopped turning the games run for a long time.

    Vista has stopped turning the games run for a long time. The display would go crazy and the sytem would lock. Gotta make a stop with the power button. No errors are recorded. I re-installed the game. Same thing. I reinstalled Vista 64. Same thing. I get about 3 minutes in the game and then locking the. 1 single game still work (BioShock2). COD - MW2 and COD MW lock the sytem. One is direct install, and the other is the steam. I have a video card Nvidia GTX 280 with the latest drivers from Microsoft. Before the reinstall, I tried to install the most recent NVIDIA. Did not help. Yet the locks without showing error. About half of the time it stops at my off video card a few seconds after that the display goes crazy. BioShock uses DirectX 10, and others use DirectX 11. I read on some sites that 11 causes the video crashes on some systems. I want to know is why 11 is working for so long and stop NOW. Is there a way to make the games all run on 10? COD BlackOPS crashes too. I played ALL these games over and over again until the last 3 weeks. If there was some error to post logs I would but there is not. Any suggestions on where to find some kind of problem that could cause this? The video card was removed, cleaned and put back into the computer. Still crashes. 1 in 4 of the games will take place without any problems. 3 will be blocking of the computer and the video trash in 3 minutes or less to start the game. The video is great, until blocking.

    Suggestions on how to fix or where to additional troubleshooting for the cause will be greatly appreciated.

  • Edition of Lightroom Mobile Sync - 'Sync has been turned off. This seems to be a backup catalog... »

    Hi, I just tried to synchronize. I am logged on LR5.4 and on mobile. I ran the sync once, that seemed to work. The next time that I'm connected, I got a dialog box saying "Sync has been turned off. This seems to be a backup catalog that can be updated with Lightroom mobile. "To do this, your catalog sync go in Edition > Preferences > mobile Lightroom and click on the button Delete all data.

    It is not a backup catalog, is my main and one alone, but I deleted all the data anyway. No difference. When I start the synchronization immediately made up the dialog.

    Any ideas?

    See you soon,.

    Scott

    Scott, you mention in your post "the next time I logged in." do you have explicitly signed out of sync Lightroom Mobile on the desktop after you sync the first time?  Or you might need to reconnect on the launch.  If it's the latter, this should not occur and could be another indication that the catalog you have signed forward is not the same (that is a backup or a copy that is not state same you were when you last signed in).  This catalog is shared between both machines somehow?

    If you see this and you are certainly not in a backup catalog, you should be able to perform the following operations with Lightroom close.  This will work better if you did remove all the data, even if it is not mandatory.  If you do not, after relaunch of Lr, we will rebuild your sync status which can take some time depending on how much you have synced.  I wouldn't do this for any other situation.

    On OSX: In the Finder go /Users/Data / Sync.lrdata Library/Caches/Adobe/Lightroom/Sync and delete it.

    Windows: In explore go to C:\Users\\AppData\Local\Adobe\Lightroom\Caches\Sync.lrdata and delete it

  • Lightroom: Sync has been turned off. This seems to be a backup catalog...

    Lightroom crashed on me and now I get the following message is displayed:

    Sync has been turned off. This seems to be a backup catalog that can be updated with Lightroom Mobile.

    To ensure that your catalog sync, go to: Edit > Preferences > Mobile with Lightroom and click the button "delete all data" to start over.

    I'm in my main catalog, not a backup.

    No one knows how to stop Lightroom to my main catalog as a backup? I don't really want to delete all data and spend the next week re - synchronize their brand-new.

    I use the latest version of Lightroom CC on a pc Windows 10.

    Thanks for your replies. Looks like I fixed it now.

    I was in the main catalog, not a return to the top.

    The issue seems to be with 1 private collection. No synchronization this collection, Lightroom is connected to the Mobile with Lightroom. I allowed him to delete the files in the cloud, then re - synchronize the collection. It seems to work fine now.
