Photoshop Histogram Question (Pixel Count)?

When using the histogram, why is it that when viewing selected lair, it shows 6000 pixels, but when using control + click layer (selecting all the pixels on the layer) it shows 2400? 
Could it be that ctrl+click doesn't count transparent pixels in the count?

Ctrl+Clicking on a Layer content is the layers palette should load that layers transparency as a  selection and cam be any shape which will be smaller or equal to canvas size.. Targeting a layer you should get the layer the bounds which is rectangular and can be any size layers can be larger then and not even positioned over the document canvas area.
Only pixel in either have color

  • Pixel counts for specific RGB values

    Can Photoshop CS4 find pixel counts in an
    image for specific RGB values?  Where would
    you input these RGB values and would you see the pixels highlighted and totaled?

    Hi Zeno:
    Thank you very much for your response!
    Your directions work very well for a single image.  I have an entire series of images and was wondering if I could just enter a specific set RGB values some where and see a total pixel count for each one of them.
    When I go to foreground color and enter the RGB values there and then set the color range to zero and press OK, I get a Warning: No pixels were selected message.
    Any additional advice that you have would be much appreciated.
    Thanks, Bretzfrog

  • DNG files not showing thumbnails preview icon on mac, after reduce/resize pixel count. Mavericks 10.9.2, Photoshop CC, ACR 8.4.0.199. Any Solution?

    This is driving me crazy. With today's huge file sizes it seem to me that for the majority of pictures a pixel count of 12-16 mega pixels y more than ok size for editing and make printings; for the professional jobs is a good idea to have the biggest file we can. Due to that i was trying to convert some NEF files to DNG, saving some space in the process, But the impossibility to preview the picture's thumbnails and the file size (it displays 0x0) immediately take me to 1984, (Windows 3.11). and those are bad memories.
         I don't know if this is an apple's or adobe's error, but it needs to be solved.
         Anyone with the same predicament?

    Thanks for your insight JimHess.  Someone else on another post pointed out how Photoshop changes the color profile and other things and then trying to make this file into a DNG again confuses Mavericks (and, presumably, other flavors of OS X).  Admittedly, the process I described is unorthodox and not what may want to do.  Thank you.
    A.J.: First, I am offended by your suggestion to omit my comment.  I was simply trying to provide help in finding a cause of a general problem people are having across the internet.  That problem, as you pointed out, is that modifying a DNG in some way in photoshop results in the thumbnail no longer being visible.  Your modification is the size.  Mine was not.  But it was a general modification in photoshop and an attempt to reconstitute the file as a DNG that seems to be common theme, whether this workflow makes sense or not.  Additionally, I'm very new to digital photography and tried to be helpful.  I would advise you (as an educator who knows the consequences of negative first-time experiences) to be more mindful that not everyone on here is as experienced as you and everyone can benefit from being clearer in their questions and their comments.
    Second, as JimHess pointed out, in manipulating a DNG file in any of the programs in a way that alters the actual file (not changing some setting that is ultimately stored in a side-car file or does not actually alter the photo) is probably the root of the problem.  Changing the file size by altering pixel count may first require one of your adobe products to physically alter the file information in a way that stops Mavericks from being able to recognize the contents as RAW information.  Does this make sense?

  • File size vs pixel count - slowing down my library?

    Hello all,
    I've been scanning 35mm slides at a high resolution (so that I can enlarge, crop, etc) then loading into my Aperture library. The files are between 5-7 Mb each but are approx 8000x5500 pixels which I calculate to be 44 megapixels. I currently have about 750 of these files (plus a few thousand pics from my xsi) in my library and they seem to be really bogging down my 2006 macbook, especially if I try to round-trip to photoshop or print a light table to PDF. It just comes to a screeching halt. I know that for 99% of the pics this resolution is overkill, so I'm planning on exporting them all to fit them to a 5x7 print at 400dpi. I'll then remove the originals from my library and re-import the smaller files.
    If I export the jpegs at a quality of 12, the file size doesn't change too much, even though the pixel count is now only 5.6 megapixels. So my questions are:
    1. Are these large files really bogging down my machine, or is there something else going on?
    2. Will reducing the pixel count have any effect on performance, even if the file size doesn't change much?
    3. Will reducing the file size (ie, change the jpeg quality to 10) have any effect on performance?
    BTW, all files are referenced masters, my library is on one usb drive, and the masters are on another usb drive. This is the best I've come up with, given the limited space on my internal drive. Could this be slowing me down?
    Thanks a lot,
    John

    MacDLS,
    I recently did a little house-cleaning on my startup drive (only 60Gb) and now have about 20Gb free, so I don't think that is the problem.
    It's probably not a very fast drive in the first place...
    I know that 5MB isn't very big, but for some reason it takes a lot longer to open these scanned files in photoshop (from aperture) than the 5MB files from my camera. Any idea why this is?
    Have a look at the file size of one of those externally edited files for a clue - it won't be 5MB. When Aperture sends a file out for editing, it creates either a PSD or an uncompressed TIFF after applying any image adjustments that you've applied in Aperture, and sends that out. Depending on the settings in Aperture's preferences this will be in either 8-bit or 16-bit.
    As a 16-bit uncompressed TIFF, a 44 megapixel image weighs in at a touch over 150MB...

  • Total pixel count for specific shades

    I am photographing fixed points along an artificial stream bed and want to document algae growth in it over time.  There may be up to 7 different shades of green (types of algae) in a given photograph.
    Can Photoshop CS4 separate these shades and give you a total pixel count of each shade? 
    I was told by techical support that if you select an area with a tool that the histogram can give you a pixel count (along with the RBG values) for that given area.  Is there a way to click on a particular shade point and have PS computate the total pixel count of that shade in the entire photograph.
    The magic wand tool does not appear to be a reliable tool for this purpose.

    Hi Paulo:
    Thanks for your response!  When I go to Select/Color Range and set the bar to low fuzziness, I get an eye dropper.  When I click the eye dropper on the photograph, nothing happens in the histogram to indicate a pixel count.  I am missing a step?
    Thanks, Bretzfrog

  • How can I increase the pixel count (tolerance) that will invoke sizing handles to make them easier to select and use?

    When working with Word tables, re sizing a column's width requires placing the mouse exactly on the line, waiting for the mouse pointer to change to the sizing control, and then you click and drag.  The problem is that the tolerance is so unforgiving
    (a few pixels one way or the other) that is rather difficult to get and keep the mouse in exactly the right spot to invoke the sizing handle.  Because the tolerance is so narrow, by the time you click to drag, the handle control often reverts to a regular
    mouse pointer because you moved the mouse a pixel, and instead you find yourself highlighting cell content instead of dragging the column width.  And you have to keep repeating this process over and over trial-and-error fashion until you finally get the
    sizing handle to display long enough to actually invoke it when clicking.   It is rather frustrating.  My question is this:  Is there a way to increase the tolerance to invoke a sizing handle?  In other words, increase the pixel count slightly,
    either side of the line, that will invoke the control for the sizing handle?   Instead of a few pixels, to something much more realistic/functional, like maybe 5 to 7 pixels either side of the line.  This is also a problem when dealing with columns
    in Windows Explorer - you find yourself dragging a column instead of re-sizing it because by the time you click the mouse, the sizing control has reverted to a regular mouse pointer - this has long been a source of wasted time and frustration to me.  I'm
    hoping there might be a way to change this in the Windows registry.  Thank you.   

    Cool article, but not relevant.
    I did not import from iPhoto nor Aperture.
    I have my photos as JPEG files in a folder on my hard drive.
    Photos, the app, did not make any duplicates. Rather, it made a giant Resources folder, almost as big as my folder of Image files.
    FInder Info confirms the size increase and lost capacity on my hard drive.
    But I appreciate the link.  That could certainly give someone the same impression.

  • Images coming in at wrong pixel count

    When I started making my website I put a background image in that was sized perfectly in Photoshop. I made the pixel count identical to the size of my website. Today I went to edit the background image in photoshop and remove a few lines from in. I saved the image (the pixel size, count, and ratio were never altered) and relinked the file into my website. The file is now coming in way too small. I tried bumping up the pixel count (drastically for good measure) and the image is still coming in way too small. Anybody have a solution?

    If you open the assets panel and mouse over the entry for this image, you should get a tooltip describing the size of the image on disk, in the muse file, and the size it's being used at in Muse. A screenshot of that tooltip would be helpful.

  • Open images in the Photoshop window look pixelated, but same images in Acrobat or viewer look fine. Help in resolving? Link to screenshots.

    Some files and images I open in the Photoshop window look pixelated or choppy, but when I open in Acrobat or viewer they look fine. This just started about two weeks ago. I reset my settings, and all of the the help topics come up for blurry images/re-sizing. I have had this problem with .tiff, jpg, and pdf files.

    That black degradation in the background at the top looks like an old ATI driver bug where if for a given pixel the red channel reaches zero all three colors of the pixel would go black.  I think that was a couple of years ago we were seeing that.
    See if AMD has released newer drivers for your FirePro card.

  • If you change the image mode of this image from 8-bit RGB image to Grayscale mode while in PSCS – what will the new Pixel Count be?

    If you change the image mode of this image from 8-bit RGB image to Grayscale
    mode while in PSCS – what will the new Pixel Count be?

    If you mean by Pixel count the number of pixels, this will not change. The image will have the same size thus the same number of pixels.

  • Photoshop Saves Incorrect Pixel Aspect Ratio

    Hi everyone.
    I'm having trouble saving image files with correct pixel aspect ratios in Photoshop CS5 on a Mac OSX machine.
    When I'm working on the image, it looks like this:
    Once I save the file and open it on my desktop, it looks like this:
    I've tried saving the file in Photoshop under different pixel aspect ratios, but none seem to do the trick. I'm a relative novice to this stuff, so I don't know if what I'm missing is right in front of my nose. Any help?

    Try this:
    Create a new document (Command+N), and in the New Document window, make sure the Advanced settings are showing at the bottom. Under Pixel Aspect Ratio, make sure that Square Pixels is selected. Save that document and see if the aspect remains.

  • Can LR filter or sort by pixel count or file size?

    LR ought to sort or filter images by pixel count and by file size. I can't seem to figure it out. Consider adding this capability.

    No, but no harm in asking for the Feature.

  • How do I prevent Adobe DNG Converter 7.4 from cutting image pixel count?

    I converted 5D Mark III Raw files to DNG with Adobe DNG Converter 7.4. When I import the DNGs into LR I noticed that the total pixel count has been significantly reduced. The original Raw images are 22 megapixels (5760 x 3840), the DNG files are 10.5 megapixels (3960 x 2460). I tried it without lossy compression, and with Lossy compression (making sure preserve pixel count was selected). Either way the image's pixel count is reduced. How do I avoid loosing half the image? Am I missing something?

    Simplistically,
    The image is captured with the full sensor data and then is downsampled during in-camera processing to create a smaller version that retains the Raw bit-depth. That resultant file is saved on the camera's memory card. So while all the MP of the camera were used, the output file is smaller in MP.
    There are probably much better technical explanations for how that happens. http://dougkerr.net/Pumpkin/articles/sRaw.pdf Pages 6 and 7,
    Mind you, I suspect this is what happened. You need to verify with your second shooter. The pixel dimensions match exactly with mRaw.

  • How to keep questions from counting toward quiz grade

    I have some checks for understanding throughout my module that use question slides. I do not want them to count toward the quiz grade at the end. How can I accomplish this? I can't make them "Survey" questions because I want there to be feedback. If I uncheck "Report answers", does that keep the question from counting toward the quiz grade?

    I couldn't find the Advanced Interaction panel (though I do remember this panel in Captivate 6 - is it still there is 7?).

  • Photo scanning -- cropping using pixel count for dimensions?

    Hello,  I have both an older Photosmart 3310 and a new Officejet Pro 8610.  When scanning using the 3310, I can control cropping of the previewed scan using pixel count (width and height).  I can't seem to do that when scanning using the 8610.  Dimensions are in inches and only.  In fact, my editing options on the previewed scan on the 8610 seem quite limited relative to what I can do using the much older 3310.  Am I missing something?  I want to scan on my new 8610, but I also want some control over the scanned image like I had with the 3310.
    Thanks.

    Hello there! Welcome to the forums @JGH28 ,
    Yes, you are in fact correct. The software definitely has changed over time and is much more limited with the software for your scanning options for the Officejet 8610 compared to your Photosmart 3310. Unfortunately there is not a way to change the options you have to broaden them again.
    I would only suggest to ensure you have installed the Full Feature software for your Officejet 8610 to ensure you are seeing the full options available for your printer: HP Officejet Pro 8610 e-All-in-One Printer series Full Feature Software and Drivers
