How do I compare images in CC

I am using Photoshop Creative Cloud - I have 4 images loaded into photoshop. How do I display all 4 images at one time so I can compare them.

I am going to assume Windows - I don't know if it works the same on the Mac (Information about the OS would be useful).
By default when you open a file in Photoshop it is "Docked" to the main window. If you have 4 files open you will have them all "docked" to the top of the window as tabs (IE you can click on the name of each individual photo and that becomes the focus and gets displayed). What you need to do when you click on the name of the photo in the tab in Photoshop is to drag it down slightly and it will become un-docked and will display in its own floating window. Do this for all of your photos and then resize and move the windows around and you will be able to compare the photos.
Cheers

How can I comparing image at a specific display size?

Respected sir/madam,
I want to compare two images with their pixel values.But actually images are around 600MB size.
Is it possible to check images with some temporary width,height like 100*100 or etc.
Regards,
M.Suresh Kumar

As you ask the question right now, you are talking about scaling down the images to 100*100 which would be "not a good idea" - I assume that's not what is on your mind at all.
Are you perhaps thinking about comparing the images not as a whole in one go, but in stead cutting them up on smaller pieces of 100*100 pixels and comparing those?

How can I compare a (partial) export folder from iPhoto to an event in iPhoto to find images not exported?

How can I compare a (partial) export folder from iPhoto to an event in iPhoto to find images not exported? Or better yet, how can I export selected events to a new iPhoto library or an existing iPhoto library with events, titles and keywords intact?

How to import a image and compare with another image to find their deviation

i am new to labview , can anyone tell how to import a image and compare it with another image to find their deviation
Solved!
Go to Solution.

This is an quite easy task using the Vision Development Module.
There you can acquire images from cameras or read them form the harddrive, then differntiate them or since VDM 2010 calculate the optical flow between consecutive images.

Organizer 12 - how to: zoom over 100%, use the Trackpad, compare images?

English Version below.
Hallo zusammen. Ich bin von Apple Aperture auf PSE 12 gewechselt. Nun habe ich meine 11500 Fotos im Organizer und ein paar Startschwierigkeiten.
Ich habe in den Voreinstellungen angegeben, dass man Fotos auf über 100% skalieren darf. Das funktioniert aber nicht. Fotos werden immer nur im Fenster eingepasst, wenn der Zoomhebel ganz nach rechts steht.
Einzig in der Vollbildansicht kann man über 100% skalieren. Dies funktioniert aber auch, wenn ich die Voreinstellung dazu nicht gesetzt habe.
ie vergleiche ich mehrere Bilder? Im Handbuch steht beschrieben, dass man dazu aus dem Menü Ansicht -> Bilder Vergleichen wählen soll. Diesen Menüpunkt gibt es bei mir nicht.
Auch bei dem Druck auf F12 geschieht bei mir nichts. Kann ich die Tastenfunktionen irgendwo neu zuweisen?
Zu guter Letzt: kann ich die Zoom & Pinch Funktion des Magic Trackpads irgendwie einschalten? Das vermisse ich sehr. Da war Aperture sehr Bedienerfreundlich.

Hi there. I switched from Apple Aperture to PSE 12. Now I have my 11500 photos in the Organizer and a few teething problems.
I have specified in the preferences that you can resize photos to over 100%. This does not work. Photos are always fitted only in the window when the zoom lever is all the way to the right.
Only in the full-screen view you can scale over 100%. However, this also works if I have not set the setting in the preferences.
How do I compare multiple images? The manual describes to select from the View menu -> Compare images. This menu item does not exist for me. (German Version)
Also by pressing F12, nothing happens. Can I re-assign the button functions somewhere?
Last but not least: How can I use the zoom & pinch from the Magic Trackpad? I 'm missing that very much. Aperture was very user friendly with that.

You cannot zoom in on an more that fitting the screen space will looking at images in the Organizer's image well. This size may be much smaller than 100%.
There is no preference to "resize photos to over 100%".
There is also not a Compare option in the View menu.
To do either of these options (from the Organizer) you have to be in the Full Screen mode. From here, you can use the mouse wheel (or trackpad) to zoom up to 1600%. You can also compare images by selecting the Side-by-Side or Top/Bottom display from the "View" Options button on the Full Screen options bar.
To use the F-keys, you have to add the Command key, so Command+F12 will open the Full Screen Mode in side-by-side compare view.
If you purchased Photoshop Elements as a replacement for Aperture, there are a lot of differences that you will have to adjust to. Photoshop Elements and Aperture are hardly complementary applications. If you were looking for something like Aperture, you should try Lightroom instead.

Hello Barbara and thank you for your answer.
I've ment side by side view. And it works by pressing F12 + cmd. Thanks.
Zoom & Pinch only works in the Editor, but not very well or smooth. And I couldn't tell you how often the Editior rotate my images unwanted ...
In the preferences of the Organizer, there is no point for a scroll wheel. And I'm really not able to zoom in the organizer over the "fitts in screen" size.
And I've found some more problems Sometime I'd like to export my images without any Exif/Metadata Information and resized. I haven't found any point do do so.
At the Moment, I'm thinking about switching back to Aperture, where I came from - I've tried to use PSE 'cause of Adobes Raw Converter, which is much much better with Olympus RAW Files than Apertures.

How does Mercalli compare with FCP X's Image Stabilizer?

Last night we were shown some videos which had been stabilised using Mercalli.
http://www.prodad.com/home/products/videostabilizing/300391667,l-us.xhtml
The steadiness was excellent but as we were not shown the original footage there was no way of judging the improvement.
Has anyone used this system and if so how does it compare with FCP X's stabiliser?

aside Luis' excellent reply:
* consider to upload your video to YouTube and set it there to 'hidden' or 'privat'. By eMail, share its URL. Many ISP have a max for eMail attachements, and video is huge by nature...
* poor-man's-Compressor is the free tool Mpeg Streamclip.
It offers in its various Options lots of settings, you usually would do in Compressor. Just share a Master from FCPX, open it in Streamclip and then 'export' it in any compressed form you like, e.g. reducing resolution, frame-rate, bit-rate. Less convenient than Compressor, which would allow to add your very own settings/'destinations' into FCPX... but cost-free.-

How to "loupe" thru images?

I've used LR for a while now, and my basic workflow has always been:
1. Import images from my SD card into LR
2. Review the imported images in LR using the Loupe view and the right (and left) arrow keys
For some reason this does not work anymore. Here is what I am experiencing:
1. Show images in the Grid view with no thumbnails selected.
2. View one image in the Loupe view. Does not seem to matter whether I double-click a thumbnail or single click then press the E key.
3. The right arrow key show either the next thumbnail, or the 1st thumbnail on the grid (see to be random which thumbnail is chosen)
4. Subsequent left or right arrow keys toggle the view between the two image noted above.
5. Switch back to the grid view shows the two image noted above selected.
I've combed the preference settings an I do not see anything for "auto select" or "auto next". I know the LR has not always behaved this way, so I assume I've done somthing to put it into this "mode". THe other possibility is that I now have 20K+ images in my catalog. Is this too many?
I've found a work-around to this "situation" by selecting all of the thumbnails in the grid that I want to see before I enter the Loupe view, but I know I have done this in the past. Could it be that a LR update changed the way the LR works?
Thanks in advance for any light you might shine on my light room :-)

Thanks for your post gatorjim. I'm running LR 3.3 on Windows 7. I have no keyboard macros defined, and the keys do the normal thing on the grid view and in other programs.
OMG - I just fixed it. I was probing on how to reset my preferences, and I happened to look at the menu option Window / Secondary Display. I have a 2nd display that I rarely turn on, but my LR setting was Window / Secondary Display / Show and Compare (probably because I had inadvertently hit the key combination to activate it, although I was not aware of that because I rarely turn on the second display). When that's set, LR behaves as documented in my original post. Once I set Secondary Display to "Loupe- Normal", now the primary display behaves as expected: I can sequence thru images in the Loupe view using the arrow keys, and I experience no "auto selection".
I'm sure all this makes sense if you use a secondard display to compare images, but it sure threw me for a loupe (groan... I could not resist).

Comparing images from different cameras

I recently tried to compare images taken with a Nikon D300 (12.3 mgapixel-small sensor), D800 (36 megapixels-large sesnsor) and D4 (16.1 megapixels - large sensor) using the LR4.1 Compare function with not very satisfactory results (iMac 27, Lion). I took 4 images each of the same subject with a 60mm f2.8 Nikon lens on a tripod at F8, at 200,400,800 and 1600 ISO and imported the images into LR. Selecting images of the same ISO and using the Compare function, they all looked pretty much the same so I viewed them at 1:1 and 2:1 trying to get a closer look at the fine details to check for sharpness and noise. Regardless of how I cropped the images, I couldn't get any of them from the different cameras to be the same size on the screen in the closeup views. I presume the combination of sensor size and megapixel capture on the sensors caused this problem but I don't have the technical expertise to either understand (or care). Is there a way in LR to overcome these differences? If so, how? Thanks for any help.

Obviously, Lightroom was not designed to handle this specialized situation. This comparison would be a piece of cake in Photoshop (or Photoshop Elements or most any other true editor), but I cannot think of a way to make this happen in Lightroom.

How can i compare the contents of two folders ?

how can i compare the contents of two folders and find out which files are in one but not in the other?? Knowing how to do this would be the best thing ever, especially when dealing with a large number of files. Often, for instance, I'm dealing with a large number of images, processing them, and saving the retouched ones to a new folder, and need to check that they are all there. If there are say three files missing in the second folder (out of say a hundred in total) being able to automate the process of elimination would be very useful. Please help!!!
B

I really wish I knew the answer to this. I work between two macs, a G5 and MacBook Pro when I'm on the go. Each time I move from one to the other I have to copy all my files to the computer I'm going to work on, so I end up with the same files being duplicated. It's not a problem if it's not much data but in my case the it can be to 30GB, mostly graphics files, photoshop, motion, final cut pro, etc.
There's has got to be a way automator can make a comparison between two folders to sort out what's changed and what's remained the same. It would be nice also if this feature could be done globally on the hard disk using spotlight's technology to stop files being duplicated in places you didn't even know about and taking up valuable disk space. I'm not sure how this could be done.
Any bright ideas Apple?

How to capturing scrolling images with no java controls?

Can somebody help me? I am trying to capture the image of the browser, using the followed code to do it, but I can not take it scrolling the screen. I do not use any control of java in the browser. Does anybody have an idea?
Robot r = new Robot();
image1 = r.createScreenCapture(clippedScreen);
File file = new File("c:\\Csa\\3.9\\Fimages\\"+counter+".jpg");
javax.imageio.ImageIO.createImageOutputStream(file);
ImageIO.write(image1,"jpg",file);
//Scroll the screen
scrollTheScreen ();
//Takes scrolled area
image2 = r.createScreenCapture(new Rectangle(0,666,1280,80));
File file2 = new File("c:\\Csa\\3.9\\Fimages\\"+counter+1+".jpg");
javax.imageio.ImageIO.createImageOutputStream(file2);
ImageIO.write(image2,"jpg",file2);
As you can see I take two parts of the screen but I am having troubles adding the images, I do not know if there is an easier way to do this.
Thank you in advance.

Thanks to anybody, but i found the way on how to capture the image.
1. Take a snapshot of the screen.
2. Scroll the screen pushing the button down.
3. Take the snapshot of the scrolled part of the screen.
4. Scroll the screen pushing the button down.
5. Take the snapshot of the scrolled part of the screen.
6. Compare the 2 last images, if they are equals, stop scrolling, else scroll again.
7. Join the images first, second and third images, to get a single one corresponding to the hole info of the browser.
8. Save the resulting image.
The thing in this problem is to manage the images as RGB components for that you must use the getPixel(col, row, color); method to manipulate the components in matrix and added to a bigger matrix where you join the complete components. Be sure that you manage the 3D matrix correctly, [width of the screen] [height of the screen] [RGB components], i.e.
* This saves just the red component, the green and blue must be saved too.
public int[][] imreadRed(BufferedImage bi)
          Raster r = null;     // * Raster
          int [][] image;     // * Image array
          int imageWidth = bi.getWidth();     // * Image Width
          int imageHeight = bi.getHeight();     // * Image Height
          int[] color = new int[3];     // * array to colors RGB (r -> 0, g -> 1, b -> 2)
          r = bi.getData();
          image = new int[imageHeight][imageWidth];
          for(int row = 0; row < imageHeight; row++)
               for(int col = 0; col < imageWidth; col++)
                    r.getPixel(col, row, color);
                    image[row][col] = color[0];          //Saves the red color to the array image on the first coordinate
          return image;     //Return the array with the red component
     }* This merge the matrix into a bigger one.
public int [][] mergeMatrix (int [][] mat1, int [][] mat2){
         int rowsMat1 = (mat1.length-53), colsMat1 = mat1[0].length,     //mat1.length da los renglones de la matriz height
         rowsMat2 = mat2.length, colsMat2 = mat2[0].length;          //mat1[0].length da las columnas de la matriz width
         int [][] addedMatrix = new int [rowsMat1+rowsMat2][colsMat1];
         for (int row = 0; row < rowsMat1; row++) {
              for (int col = 0; col < colsMat1; col++) {
                   addedMatrix [row] [col] = mat1 [row] [col];
          for (int row=0; row < rowsMat2; row++) {
               for (int col = 0; col < colsMat2; col++) {
                    addedMatrix [rowsMat1+row] [col] = mat2 [row] [col];
         return addedMatrix;
    }* This convert the matrix into an image.
public BufferedImage imwriteComponents (int [][] arrRedImg, int [][] arrGreenImg, int [][] arrBlueImg) {
          int arrayWidth = arrRedImg[0].length;     // * Image Width
          int arrayHeight = arrRedImg.length;     // * Image Height
          BufferedImage completeImage = new BufferedImage(arrayWidth, arrayHeight, BufferedImage.TYPE_INT_RGB);     // Create a BufferedImage with RGB pixels
          WritableRaster wRaster = completeImage.getRaster();     // Create a raster so we can access the BufferedImage pixels
          int [] color = new int [3];     //color variable to save all the components
          //join the 3 matrix in one color type
          for(int row = 0; row < arrayHeight; row++)
               for(int col = 0; col < arrayWidth; col++) {
                    color [0] = arrRedImg [row][col];
                    color [1] = arrGreenImg [row][col];
                    color [2] = arrBlueImg [row][col];
                    wRaster.setPixel(col, row, color);
          return completeImage;     //Return the Buffered image with the red array component
    }That is a solution that I found to this problem, if someone has an easy way to do it please tell us.
Thank you.
