Image with my .iagonal 6 d line problems.

Hello, my name is Lindy and I'm new to this forum. I had a problem with my Canon 6 d which translates some of my images appear with a diagonal black line in the upper left corner. I have seen this problem with my L 100mm lens and my 16-35mm lens. If anyone has had this problem before or have any idea what can be wrong?

Thank you!!

Hi Lindy.  You have a little 'dust' on your sensor (only in this case, it looks like a little hair).

It is easily fixed.

See page 279 of your manual owner who describges how to clean the sensor.

I do, however, is recommended that before making an automatic cleaning cycle, you remove the lens and point it at the ground - it's that this bit of hair has a place to go when she falls... other than to find another location inside your camera.

After cleaning, punch the camera a plain white wall (or ceiling) and take a photo (it doesn't even have to be developed).  Dust looks better to the high apertures (it'll be more blurry at the bottom diaphragms).

Sometimes automatic cleaning is not sufficient and you need to do something more.  If this is the case, then see page 283 for "manual sensor cleaning.  This simply causes the camera to turn off the sensor, but open the shutter (and keep open) so that you can inspect and clean.  If you look inside, what you REALLY see are the two filters in front of the sensor.  The before filter is one that vibrates (using a piezoelectric effect) to "shake up" loose dust.

I use a variety of techniques... the easiest and safest is to use a fan simple hand - squeeze (bulb) as a Giottos Rocket Blower.  I recommend that you use no compressed air cans, because the liquid propellant in the boxes can spray if the can is shaken or not held perfectly level and that leaves a residue on the filter (and the only way that come out is to wet - clean the filter).  Even air compressors spray water and oil.  A hand blower pressed is the safest option.

If this does not work, I use a small, extremely soft brush.  They do actually brushes that plug in to release static electricity so that if something is stuck because of the electrostatic control will be released if all goes well.

If this does not work, I use a range of sensor to inspect my sensor and get a better understanding of why he won't not always free (because usually there now) and wet then clean the sensor using photographic Solutions sensor swabs 'brand' and 'Eclipse', cleaning solution.  The solution is almost pure methenol which means it evaporates quickly and leaves no residue.

My guess is a simple manual cleaning (with the camera pointed at the ground) - or - a hand blower pressed will probably do the trick.  If you use a brush, give this brush some good solid shots on the edge of a counter or table to shake the dust that could be on the brush - because you do not want to add to dust on the sensor you're trying to blow that hair.

More 'real' camera records (company mainly to sell stores and material service photo - not large areas that are also sell cameras) offers sensor cleaning, but there is usually a charge related to that.  It is pretty easy to learn how to clean the sensor (which is why Canon has a section in the owner's manual) and it is something photographers have to do... only occasionally.

  • Newbie: background image with overlay problems

    I use a large background image with several circles superimposed over the image. When the image is resized to different browser screens, overlays remain unchanged, even if the changes of background image to fit the browser. As a result, overlays eventually his place with respect to the substantive parts and cover image, I don't want to not covered. Clearly, I'm a newbie with dreamweaver. Useful links?

    This approach to layout does not work in flow layout (%).   APDivs are removed from the normal document flow and thus remain absolutely where you positioned them.

    Cards images do work either in fluid layouts.  As the picture re-sizes to fit the display window, the hotspot regions are not.

    When you create responsive Layouts, review your Mobile implementation objectives first.  Then tablets and desktop computers.  And above all, to keep things simple.

  • Rolling/down shifiting image with low level acquisition of VI

    Hello

    I do image with low level VI acquisition acquisition. The series of captured images appear as an image rolling/down shift. Each image is captured moves down again and again. If frame 1 a row of pixels is 0 when the row wherever the 100 frame is captured rank 1 is at line 100, giving the impression of the image slowly moving down.

    I enclose a small program through which I am able to reproduce the problem. The help of a 1426 PCI capture card and an impressive camera (double IPX-2M30H-L).

    Can someone tell me please what is wrong with this program and how I could fix this?

  • How to create a camera profile that works with a JPG image with my color chart to check inside? [was: color Checker chart.] Really need help]

    I got a color chart to check. It came not with any software whatsoever. I shoot my images in JPG format. I know it's not really ideal but I'm on a tight budget and don't have the money for a digital SLR cameras that shoot raw. Is there anyway that I can always create a camera profile that works with a JPG image with my color chart to check inside? My table also includes RGB values below each color. Maybe I can match each color in the photo these values manually? If so how is this done?

    Thank you

    Bryce

    I've never seen software that does what you ask for JPGs, only RAWs.  The main problem is that any profile or adjustment is calculated according a JPG of a particular chart photo would apply to the other JPG photos with the same white balance.

    Jpg does not use "camera profiles" anyway in Lightroom, the profile is always integrated.

    There is a product that allows to calculate the HSL cursor offset values given a JPG photo their own table owner who looked like a color checker, but had two lines reversed so the software could not be used with a standard-checker color, unfortunately.  Now their table has twice as many patches (48), and looking at it on their site I'm not too sure that it does not always work with JPGs or if she's just raw files, now.

    The graphic and software are called SpyderCheckr of Datacolor.  There are various software that do different things, but none are using a ColorChecker, so having one is mainly a loss until you get a camera that can take raw photos, so keep a humidity and temperature controlled environment as much as possible until you have the right camera.  You can probably use the grey patches to adjust exposure, but that's all.

    Today you need not a digital SLR to have raw photos, well.  My phone Galaxy S6 with the last update of Marshmallow and the software of camera update will take photos in format raw DNG in Pro mode which I can create custom profiles camera to use a ColorChecker, although the camera is really good in itself, so when I found everything first he could make DNG I took a little but now, I usually just use the camera to make the jpg unless the shot is really important and the lighting is not too hard.  I think that S7 phone's camera is even better.

    What kind of camera do you have?  Sometimes, there are firmware hacks that allow the camera to shoot raw format even if the standard camera cannot.

    Is - this windows or Mac?

    Also an update on the version of Ms Office installed on your system.

    Do you feel it work with all the PDF' or a specific?

    If you are using windows, try to repair Acrobat once and then see if that solves the problem.

    Also, check the latest updates installed on your computer.

    Launch Acrobat > navigate to help > check for updates.

  • Multiple images with the same file name no doubt prevent export

    iMac running OS X El Capitan v10.11.6; Photos 1.5

    I'm trying to export approximately 331 images and I get an error report saying that only 169 of the exported images due to the inability to create files for 159 of the images.  Then the report gives me the names of files of the first 100 images for which files were not created.  After looking at many images that would not create a file, I realized that, in any case, there was at least one, if not several, other images with the SAME EXACT FILE name as the image in question.  I can't change the names of files by right click on "info".  I tried to export the images and change the names of files to export using the sequential option and the option of album name - always having exactly the same problem.  I even tried not to export an image at once and change the name of the file individually or no available. Is there a work around that? I desperately need to export those specific images. I am trying to create a photo album for shown to mothers who choose a family with which you want to place their child/ren for adoption. I'm at my wit's end.  The kicker is I'm moving towards trying to export all my pictures, and that's going to be a HUGE problem in course for me, so I really hope that there is a way around this question somewhat simply. I am a hobby photographer and use the computer for businesses and crafts.  I've seen a few posts that included answers referencing "AppleScript" - I have no idea how to do something like that.

    From here on I will DEFINITELY ensure that my Canon continually numbers the names of image files and automatically resets.  For the other photos other than Canon, is possible to rename images during the import of the lot?

    All advice and help will be GREATLY appreciated!

    Finder has the ability to rename files with various models of lot.  Simply select all the files to rename, right-click one of the selected files, choose 'Rename X points... '. ", and then set the options and click on the button"Rename ".

  • Line problem vertical screen satellite 3000

    my laptop is Satellite 3000, it had vertical line problem now, I want to use an outdoor screen tube to replace the current damaged LED screen.

    I tried to use the swap FN + F5 key, but it's still doesn't work, I tried to log into the system to check, ((windows xp) system is normal), but I don't see anything because the screen is black, it will not be in the system even if I have in connected to the local network, because the configuration of mobile network function is forbidden to communicate with the internet , (I ghost before it has completely damaged), the question is:

    1, I have to configure something so she may use it outside the screen in windows XP? or just use the FN + F5 swap button?

    2, how am I going to do next step if I want to use the external screen?

    thx a lot

    Hello

    the first question you should ask is, if the machine works really well. This means that all THE drivers are installed and so on.
    The other thing is:
    When you connect the external monitor to your computer, you see something while turning on the machine? (Logo of Toshiba, Windows XP start screen, etc.).
    Usually, you should be able to work on an external display, and if all drivers and tools (such as FN + F5-> change device display tool) are installed, then the "display" button should be possible.

    Please answer and describe if you see something that we can do some better troubleshooting.

I realize that, by making this method causing too many uses of the memory/cpu and can cause CPU hang up. If I stop the program, the memory/cpu counter are down.

  • Saving binary Image with overlay?

    Hello

    I'm having some trouble in saving an image with overlay information. I use IMAQ find circles to measure the rays of the holes in a binary image. Hole data is then used with oval Overlay IMAQ, draw on ovals to highlight detected circles. Works very well and the image is displayed as expected in the output of the image on the screen, the palette has the binary value. (See the second image of 3, below)

    When I try and save the image in PNG I just get a blank image (black). If I use the overlay IMAQ merge tool, I just get the green circles on the black (see the last picture of 3 below). Is there something I'm missing with pallets/fusion? Any help much appreciated. Snapshot of the (messy) code attached.

    The problem is that the binary image is all zeros and ones.  A normal image goes up to 255, so the value 1 appears black.

    One solution is to multiply the binary image of 255, which makes the image black and white.
