Photoshop :: PS CS4 Histogram And Floating Windows
Oct 30, 2008
How do I get Photoshop to open with floating windows and the histogram in compact RGB mode? I have to reset this every time I open a new photo. I can't believe how hard it is to change modes in the histogram.I have to undock it, change it to expanded view, change the mode, change it back to compact view and redock it. This made sense to someone? I tried saving the workspace.
I was experimenting a little bit with the dockers at the right side of the workspace of Corel Draw X5 and now for some reason when I go to "Window" and select a new docker to open, the new docker appears not nested with the rest as it did before, but as new floating window so I have to add it to the rest as a tab manually which is not handy. Up to now each new docker would appear already nested. This is annoying because I really liked the way the dockers appear nested in tabs in X5.
How I can make the dockers appear again tabbed once I open them?
Does anybody knows wich was the first PS version to include this window? silly question but I cant find it in version 7, I think the one with the eye in it´s logo.
I sometimes see a razor thin line on the right edge.
Is that clipping?
I mean it very clear when I see the mountain slamming up to the right, but many times I see a normal mountain rise and fall, and then seem to see this razor thin blue green or red line on the right edge.
about cs6 , why the histogram is always set to colors? i mean is a bug like cs5 it should be set by default to rgb  every photo i load it's always set to colors and i guess there is not option to save and have rgb by default.
I am using the histogram function in PS CS4 for Windows. I am using the magic wand tool to choose numerous "green" elements (for example). As I choose more and more elements, the pixel amount goes up in the histogram table. For some weird reason, when I choose enough elements to hit around 50000 pixels, the amount reverts to 12000 and goes to "cache level 2". I need to be able to have a total of all my elements for the project I'm working on. Is this a memory issue? How can I increase the cache?
Why the histogram for a gradient is not flat, as I guess it should be? Or, how to make a gradient that results in a flat histogram (that is, with the same number of pixels for each level)? The screen capture annexed should clarify the subject.
For a research project, I am calculating the area of the cytosol of a cell by finding the total cell area and subtracting the total nuclear area. I have been using the lasso tool to select the boundaries and then the histogram to measure the total pixels in that selection area. Proportionately, the nuclear pixel area should always be smaller than the total cell area since the nucleus is inside that cell. Most of my measurements have been accurate, but I started to run into the problem in which occasionally the nuclear pixel area is larger the total cell area. This does not make sense, which means that Pixel # that the histogram records must not actually be counting every pixel. I have tried to do some reading online and it sounds like the histogram is made based on different color intensities. If that were the case, that histogram pixel count is not the total area of the selection but rather only the pixel count that is being used to calculate the histogram.
I have tried changing the Channels from grayscale to RGB, etc. to see if that might use more of the pixels but there is no difference. What is the difference in these measurements and how can I make sure that the histogram counts every pixel?
Also, once I have that issue figured out, to convert my pixel count to a cell area, do I use the equation
A=P/s^2? A=real cell area P=pixel count S=linear pixel/cm.
I have a bar scale from the microscope on the bottom of each image, thus I can accurately find this variable. I would have to square it since I need the area. Does that look correct?
On a number of tutorials in Photoshop User and elsewhere I've noticed when the curves dialogue is brought up there's a histogram laid in the background of the curves manipulator, but I don't have that. How do I get that histogram? I use CS2.
When using the Hide function on the Crop tool I understand the pixels are hidden and the info retained. My question is does the Histogram palette look at the 'big picture' on the Hide function, and the histograms in either Levels or Curves only look at what is visible?
I'm guessing this is so, but was wondering if someone could verify it. I ask because of the difference in the histograms when using Levels or Curves compared to the Histogram palette.
I am trying to collect the mean, median, and mode of the RGB color values for a lot of different images..  Instead of just exporting the histogram raw data, I would rather just export what you see in the 'statistics' window when you open the histogram window.  Also, if I just wanted to transcribe it myself, I am not even able to keep the histogram window open while typing the data in excel.. So I constantly have to click back and forth (or just get better memory)..
I use the histogram feature in PS to figure out how many square feet of yarn I will use in a rug that I am making (I work as a rug designer). I am running into a problem with this which is scary because my numbers have to be accurate. Â As an example, I may have a 9x12 (inch--this is later blown up to feet using a transparency) drawing. In the drawing there may be 45 organic looking shapes that will be green. I use the magic wand tool and choose all of these green shapes. What I am noticing is that once I get to a certain number (not always consistent) in the histogram reading it will all of a sudden change to a different number and go to (for example) Cache 3. Because of this I have no idea if my histogram reading is accurate. Â Is this some sort of memory issue? How do I prevent this from happening so that I can get an accurate heading?
I was investigating something else, and I saw something not working... I'm under the distinct impression that the Histogram panel should automatically update after every operation. Having the Histogram panel displayed full-time on the screen, it should always be up to date.  However, when I Dodge or Burn or even paint color on an image, the Histogram is not updating. If I select one of the History states I've just created, it updates.Consider this simple sequence of operations:  I'm able to reproduce this failure in Photoshop CS5 as well, BUT NOT IN CS4 (it updates in Photoshop CS4 after every painting operation), so clearly it's not a new bug, though somehow I've managed not to notice it in my years of using Photoshop CS5.  Is it broken like this for everyone in Photoshop CS5 and 6?Could this be some twisted attempt to try to optimize painting performance? If so, why isn't there an option to allow a user to request it to update on every operation on a fast computer with cores out the wazoo?
I prefer leaving my histogram in Photoshop CS6 in RGB mode, yet everytime I close the program and re-open photoshop, it defaults to Colors when I open a new document. How to get it to retain the RGB readout as a default?
I found out on cs5 there is a histogram equalizer with in hdr toning...I also found out that there are plugins for histogram equalizers. I did download one called kamflex it was ok but it was noisy. From my learned friends on this site can you recommend others and if so where is the best place to get them.
I'm currently recording the median luminosity and standard deviation of luminosity values in various photographs. This has been an ongoing project so I've been working on it for probably the last 4 months. Today I resumed my work and had to go back and check a previous photo that I had already recorded luminosity values for and noticed that the luminosity values that I had originally recorded were different than the values I'm seeing today in the histogram.
The attached picture shows the histogram I'm using (and have been using since I started this project). It is showing a median luminosity and standard deviation of luminosity for a photo that originally gave me this median luminosity value: 75 and this standard deviation: 27.87
I accidentally changed some setting in photoshop that affected the luminosity readings, or if the luminosity values of a photo are estimated by photoshop and thus aren't always the same etc. ?
Recently I noticed the histogram in PS4 displaying color channels instead of luminosity. And all three RGB colors seem to spike off the top of the window. Is there a way to only display the luminosity histogram curve? Also, how often would be considered normal to have to re-set preferences?
Since I capture my images in RAW, when I open them in Adobe Camera RAW (via Elements 11), what information is displayed in the image and the histogram I see?  Is it showing me the jpeg created in the camera? If so, the jpeg settings in my camera are not only important in viewing the LCD and the histogram in my camera at the time of capture. They would also be important in viewing my image when it first opens in Adobe Camera RAW.
I am working on a research project that involves evaluating the relative abundance of various colors in a leaf. The leaves that I am working with have three distinct sections of color (green, burgundy, and coral).
I have scanned images of the leaf samples on a flat bed scanner (all with the same quality) and am using the magic wand tool to determine the total pixel count of the leaf and the total pixel count for each individual color. With this data, I determine the relative percent of each color within the leaf. Code:
When I am working with various pictures in PS, I have like 10 open and every time I go out of photoshop and come back, they have all closed down to the docking window. I have to re-open them again from there, I want to STOP THEM from closing when I go to desktop or somewhere else. I want them to stay afloat. I know I can click Ctrl + mouse and "restore all windows" but that is also a nuisance because it resized my PS window and I have to push up teh layers palette again.
I have a photo on my first layer and want to add "call outs" to it. In other words, I want to draw lines from each part of the photograph to a description of what the viewer's looking at.  But the only way I can figure out how to do it is to add one call out to each layer, so I end up with 10 layers, one for each call out. Is there anyway to add all of these on to one layer while retaining the ability to move them around separately?
i have photoshop CS6 in a mac os x operative system and when i drag one image from the tabs to make it as a floating window in order to keep that image as a reference for the painting that i am working on, that floating window disappears behind my PS CS6 window like if it was part of another program when i click out of it, why is this happening.
I want to keep that floating window open all the time by the file that i working on.
I am trying to find where to turn on the floating menu boxes in Photoshop CS. Right now I have the tools, color swatches and navigator, but want the layer toolbox. I know I can go to the pulldown menu to select layers, but it is much easer to use the floating box to select my between my different layers.
Why is it that my document windows float on top of my palettes. Selecting the palettes doesnt bring to the front either. I have to move that window out of the way and them go back to my current document. This is very annoying and a major issue if its not fixable other than going back to tabbed windows?
Floating photos in Elements11, how I can keep them in the workspace like elements 6 really annoying when looking under photoshop and seeing the photo blocks my desktop or something simular or even blocks the tools bar opions at the bottom, which also seems far to big any way in making that smaller or putting it at the top like elements 6 .. ( think I may just go back tho that 6 )
I’m editing an image in Elements 11 and have accidentally gotten myself into a mode that I don’t understand and so far have not been able to extract myself from. I want to clone an item from the image. I select the Clone Stamp tool and suddenly I have a second floating duplicate of the image which gets dragged around every time I move the cursor. How do I get rid of this second floating image?
How can I get rid of the annoying floating commit/reject button when I am typing in text. It always seems to be in the way. I'd like to be able to type without the window showing up or be able to move it out of the way.
