Having to press the shutter twice button for the image on T3i

Until yesterday, I had no problem taking pictures - I am fairly new with a DSLR, (the T3i is my first), and yesterday, I was watching a video tutorial on this particular camera.  I went through the camera settings with the instructor via the menu settings, etc.  Today, I can't get the shutter to work the way it's supposed to!

If I hold the trigger to halfway, I get the autofocus to work as usual, but when I continue to push the rest of the way, the shutter closes. I have to press the shutter button a second time before I get a picture of output.  I went in the custom functions and erased all settings, (in the case where I had inadvertently put something that I didn't know I had done ), but I always have to press the shutter button twice.

Nobody knows what happened, or what I do or not do?

TIA!

It seems that you have defined for MIRROR LOCK UP if you get a picture on the second press.

Thank you!  That was the problem!  I thought I had cleared up all the changes I had made, but apparently not...

  • How can I select a level by pressing the image only?

    Once when I pressed an image, it is automatically selected the respective level. Now, no more. How can I solve this problem?

    I think you mean by the word 'level' 'layer in the layers panel. If this is the case. Select the move tool and check the brand automatic selection in the Options bar. With the move selected tool, click on the selected area and she will move to the appropriate layer in which this element appears.

  • How can I save a file that is larger than 2gigs without having to compress the image or reduce 16-bit to 8-bit?

    is this possible? I tried to save in a .psd file and I got a message saying it cannot save to the disk because it is bigger than 2gigs. ! I could really use some advice on saving a photo that I need to keep the highest quality for the very strong impression!

    Hi Kareen-

    This problem can lead to a lot of things but don't forget that to save a large file, you need to provide Photoshop with good use of CPU and good work record

    first try to set photoshop giving him memory: go in Edition > Preferences > Performance in memory use increase the Ps memory can store more in your ram... (what economy try closing all other efficiency programs)

    in Performance tab there is a group called "History & Cache": If your file is large itd be interesting to use as many levels of cache (maybe 8) and tile caching during about 1028 k size also affect the size of the large, flat tile

    in Scratch Disk leave photoshop now uses its temp file in all your drives for better performance

    If this doesn't work for you let me know your sys. config. and the amount of layers has your file

  • Increase in Wake - should not have to press the Home button to unlock

    Hi all

    I appreciate the work that the Apple development team did to iOS 10. Most of it's amazing as usual! BUT...

    The revival of the Wake feature needs an additional configuration option. In fact, some of us LIKE how quickly iOS 9 unlocks the phone and have the habit of hitting the power button to turn the screen to access the shortcut of the camera or using a finger not configured to press the Home button.

    That said, if I 'raises to Wake"my iPhone, having to press the Home button to complete the unlocking process is not intuitive. It must simply unlock and go to my home screen.

    As this MUST have been done intentionally, I think that you should give us the option attached to "Raise to Wake" function to enable or disable the duty press the Home button to unlock.

  • Adding PayPal button for slide show

    Hello world!

    I did a simple Web site for my wife, who is an artist. I made pages represent the portfolio pages, so that each page is a different selection of images and I used the miniature slideshow widget to make pages with. So far so good.

    Now, however, we want to add the ability for viewers to buy photos out of the site. I tried dragging a Pay - pal button off the coast of the 'Social' in the library of Widgets section and it works, except that it does not change its details when another image is selected. In other words, I put in place for the image one, but when I click on the thumbnail of the image two, the Pay - pal button does not change to reflect the details of the new image. Does anyone know if it is possible to do?

    I tried to 'Place' button in the text of captions, but I can't do it, it doesn't seem to work, he seems to expect a picture only.

    Please can someone tell if its possible to do - if so, how?

    Thank you very much,.

    Brian

    Hi Brian,.

    If you want to place an individual Paypal Button for each image then I suggest you use the ToolTip for the same Composition. You would need it behaves like a slideshow in the customization options.

    You can place an individual Paypal Button in each target with the picture and you can convert triggers to thumbnails by changing its properties.

    Kind regards.

  • YouTube I have to press the button "back" twice to return to the previous page

    Hello!

    FF constantly and across operating systems (I use many for most Linux distributions) fails to simply go back to the previous page when I press the button 'back' of the browser. He did it for months. Completely reset FF does not work, or not to empty the cache then restarting it manually.

    It is a very irritating problem, especially since I prefer FF so strongly on another browser and do not want to hit back twice whenever I want to go to a play list/etc. To clarify, it reloads the page/video, I am currently on, then finally doing what I want to after 2 clicks the 'back' button For someone who needs YouTube to work, as well as for reasons a many great tutorials that needs resolution as soon as POSSIBLE.

    Thanks in advance for any help! In my opinion, I've isolated probably the question enough that it is very likely to be a problem with my OS or malicious software.

    What is the most likely culprit here?

    I should also mention that this is happening not only across operating systems, but also on a laptop Lenovo G770 and an AMD FX - 8350 16 GB RAM PC desktop I built very recently.

    If it works in Mode safe mode and normal mode with all extensions (Firefox/tools > Modules > Extensions) off and then try to find which extension is the cause by allowing an extension at a time until the problem reappears.

    Close and restart Firefox after each change via "Firefox > Exit ' (Windows: Firefox/file > quit;) Mac: Firefox > quit Firefox. Linux: Firefox/file > exit)

    When I pressed the button of power quickly as that, in my view, your description it would take two thrusts to get to power be as the first was not strong enough to register. I believe that this does not work as expected and you should not be concerned.

  • Value property (signage) for the event - button press the joystick

    I tried to use my Logitech joystick button to trigger events.  I read several messages and LV help on how to register for events, and I have not found exactly what I need.

    I understand that events are generally not triggered by contributions of NON-INTERFACE, but I keep reading messages that make it sound possible.  Book LV Basics II says: "NOTE of Clusters are the only container objects for which you can generate events.  LabVIEW generates events control for clusters, before it generates events for the objects they contain, except in the case of the value change event.  They Value Change event generates the event part of the cluster, click the cluster itself. »

    So, the gamepad buttons and axes are in clusters and I'm trying to detect a change in value for items in a cluster (see the attached below .VI), but the event is not the trigger.  If I press the button 9 on the broomstick, the LED should light and channel indicator should say that the event has been triggered.  It is a simplification of what I'm trying to do, but I think that if I can do this simple case work, I can do the rest.

    It was created in LV10.

    So what I am doing wrong?

    Thank you, Ed
