Contrast ratio, hue, saturation

Is Photoshop capable of taking an image and calculating its depth of field, hue, contrast, saturation, and brightness?

I guess you can never say never with something like that, but some of it would take someone like Chris Cox. 
Overall brightness would be doable and quite easy.  Copy the BG layer, and apply a 1000 pixel Gaussian blur.  Repeat the blur (Ctrl f) until it is making no changes to the layer, and hover with the eye dropper while viewing the Info panel.  Move the eye dropper to make sure it is seeing the same value everywhere, and then do the math to work out a percentage brightness.
Contrast possibly using Caluclations and putting a copy of the BG layer in Threshold mode.  You'd need to decide on a datum and keep to it with the Threshold setting.

Hue might be worked out using the brightness method above, but on copies of each channel, if you know what I mean.
Saturation...  I am none too sure about.
Depth of Field.  Now that would need a clever clever person unless I am missing a trick.

  • Mplayer too dark, Equalizer(Contrast,Brightness,Hue,Saturation)

    Playing videos on mplayer were too dark!
    and Equalizer -> Video (Contrast,Brightness,Hue,Saturation) controls were unavailable/not working!
    After some research, I found a solution, for both problems.
    Using information on this URL http://www.mplayerhq.hu/DOCS/man/en/mplayer.1.html
    Open a Filemanager as root, and go to /etc/mplayer and create a file called mplayer.conf, and paste this code inside.
    # Write your default config options here!
    # eq[=brightness:contrast] (OBSOLETE)
    # default:0:0
    # eq2[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]
    # default:1.0:1.0:0.0:1.0:1.0:1.0:1.0:1.0
    # hue[=hue:saturation]
    # default:0.0:1.0
    vf=hue=0.0:1.0,eq2=1.0:1.0:0.1:1.0:1.0:1.0:1.0:1.0
    Remember to leave 3 empty lines at the end of the code, before saving.
    Notice I changed the 3rd default value in eq2 from 0.0 to 0.1, this will appear as 10 in the equalizer.
    This 10% increase in brightness gave me a brightness, similar to watching the same video in VLC.
    Well I hope it helps someone else having the same issue. :-)

    since front row just hijacks dvd player and such you should be able to change it in dvd player's preferances. are the tv shows from the itunes music store?

  • Why won't my adjustments such as brightness/contrast or hue/saturation apply when I click "OK"?

    The adjustments are applied in the preview, however when I click okay the adjustments are not applied and the layer goes back to the original before I tried to make the change.

    Perhaps the adjustment layer is below the image layer or the opacity of the adjustment layer is set too low or the mask has data in it (make sure the mask is absolutely white)

  • When i place my photo, the adjustments tab does not pop up, and even when i click image at the top, I cannot select any adjustments-brightness/contrast,hue-saturation, color blance, etc..Anyone know what I am doing wrong?

  • Quick question about hue / saturation / transparency

    I'm basically doing a simple photography website for a friend, and an trying out a few mouseover effects for the thumbnails.
    Initially I tried reducing the transparency, and now the brightness, but neither seem, quite right.
    Looking around online for what works well, I stumbled across Peter Lik's website.
    If you look here :
    http://www.peterlik.com
    And click on Collections to bring up a thumbnail gallery, can anyone with an eye for these things advise me as to what changes in hue / saturation / contrast etc look like they'd create the dulled thumbnail image compared with the brighter one when you mouse over.
    Many thanks.

    there are probably many ways to achieve this, but I'm a curves guy. so....
    open a curves adjustment layer. Drag the upper right highlight point down to the first quarter mark and then grab the shadow point in the far bottom left and drag this up to the 3rd quarter mark.
    then you can drop this adjustment layer onto any of the images that you are working on.
    hope this helps.

    Thank you!
    I originally just did the thumbs as a 60% opacity, but it was a default white background. I hadn't finished off a full gallery, so was showing the guy the Peter Lik page as an example of the effect. Looking at them together, we reckoned the Peter Lik one was more effective, as the reduced opacity on the white background was a bit washed out looking.
    So then I was trying different combinations of the brightness, which needed countering with the contrast, and I couldn't quite seem to get it.
    But you've hit the mail on the head - reducing the opacity on a black background is the winner!
    Many thanks for prepping that example PNG - much appreciated.

  • In Photoshop CC (2014), Hue/Saturation adjustment layer properties disappear

    I am running Photoshop CC (2014) under Windows 7 Professional.  The program is up to date.
    Today, while editing an 8-bit image, I added a Hue/Saturation adjustment layer.  Then, in the properties panel for this layer, with the on-image adjustment tool selected, I clicked a color in the image to get a range of colors whose saturation I wanted to adjust.  Next, using the saturation slider in the properties panel, I increased the saturation of this range of colors. Finally, I closed the properties panel by clicking on the double arrow in the upper right corner.
    Later, I wanted to modify this adjustment layer.  I double-clicked on the layer thumbnail to reopen the properties panel, and found that, although the previous increase in saturation was still operating, the saturation slider was back at its default position, and the range of colors that I had previously established was gone.  Thus, I could not make further adjustments to this range of colors.
    I then did some further experimentation:  I deleted the first Hue/Saturation adjustment layer, and created a new Hue/Saturation adjustment layer. I then again established a range of colors as above, again increased the saturation of these colors, and then again closed the properties panel by clicking on the double arrow in the upper right corner.  This time, however, when I wanted to try to modify this adjustment layer, instead of double-clicking on the layer thumbnail to reopen the properties panel, I right-clicked on the layer and then clicked on "Edit adjustment..."  This opened the properties panel, which, this time, correctly showed my original adjustments -- the saturation slider showed the positive adjustment that I had previously made, and the range of colors established earlier was still shown. But then, on a hunch, I added a Curves adjustment layer above the Hue/Saturation adjustment layer.  Now, when I again opened the properties panel of the Hue/Saturation adjustment layer (by right-clicking on the layer and then clicking on "Edit adjustment..."), my previous settings were gone -- the saturation slider was at its default position and the range of colors was gone!  (But the increase in saturation was still operating.)
    Thus, it appears that there is a bug in the functioning of the properties panel of the Hue/Saturation layer: In short, once you have added a further adjustment layer, you can't then go back and make changes to the properties of the Hue/Saturation layer.  I would be interested to hear if others have noticed this.  Also, is Adobe planning to address this?

    OK, I am not entirely sure I have understood your post completely, but when you edit a colour range with a Hue/Sat layer, and click off and back on again, it will default to showing the RGB values, which you may not have made any adjustment to.  If you pick the previous colour from the image, or a similar colour, it _will_ show you the adjustments.  So long as your picked colour is contained within the range of the previous adjustment.
    Ypu could also use the RGB drop down (actually they call it Master nowadays), and chose the colour that is closest to your previously picked colour.  I expect you are away that you can edit the colour range being operated on by dragging the four sliders on the two colour bars at the bottom of the Properties panel.
    Does that make sense, or am I going in the wrong direction?

  • How can I get hue, saturation & luminance visible in the Loupe?

    For the life of me I can't figure how to get visible in the Loupe - Hue, Saturation, Luminance as I move the Loupe around a photo.
    I can get R,G,B,L. Is there a secret to get the Hue in it? I checked preferences and even searched in Aperture Help. NO luck.
    I'm in Aperture 3.0.3
    Thanks

    It is a tad secret.
    Make sure colour value is set in the Loupe menu then:
    In the Adjustments inspector choose a color value option from the Adjustment Action pop-up menu (with a gear icon). HSB i smiling at you in that list
    Then it'll appear as a colour value in the loupe.
    BTW You'll find all this in the Displaying a Pixel Grid and Color Values section of Aperture help.

  • Photoshop Elements 6: Hue/Saturation as a basic layer?

    When creating a hue/saturation layer in Photoshop Elements 6, is it possible to have it act as a basic layer, adding and removing from the selection, rather than a mask layer?

      The simple method is to place your selection on a separate layer and clip the hue/saturation mask to it.
    In this example I selected the sky and pushed up the saturation to really exaggerate the blue color.
      Click to view
    1. Make your selection
    2. Press Ctrl+J to place it on its own layer
    3. Add new adjustment layer (hue/saturation) and click OK to close the dialog
    4. Hover your mouse over the dividing line between the adjustment layer and selection layer whilst holding down the alt key. Click when you see two small connecting circle appear. A downward pointing arrow will appear to show the adjustment layer is clipped to the selection layer.
    5. Double click the thumbnail icon on the adjustment layer (not the white mask thumbnail) and that will bring back the dialog box.
    6. Now use the sliders to make your selective adjustments.

  • What video effect for color desaturation? (e.g. Hue/Saturation in Photoshop)

    Hi all,
    What is the Premiere equivalent of the HUE/SATURATION adjustment layer found i Photoshop ? I am trying to slightly desaturate (about -53%) my movie to give it a more gritty look. I could easily get the look I wanted in Photoshpo by going to NEW ADJUSTMENT LAYER-->HUE/SATURATION.
    Is there a similar approach for Premiere? In the Video effects folder somewhere? Thanks!

    Use the "Fast Color Corrector and "Saturation".

  • The eyedropper tool does not work with a hue saturation adjustment layer

    I am using PS CC 2014, and the problem I am having is that when I want to use the eyedropper tool to adjust the colour range affected by a Hue/Saturation adjustment layer, rather than selecting the colour in the Properties window for the adjustment layer, use of the eyedropper closes the properties window and changes the foreground colour in my palette.
    Here's the real hitch... the same thing happened to me at school last night where a) the Mac's are older and b) CS6 is still used.
    It's something with my user settings, to be sure, because the prof logged into his account on the Mac I was using in class to test it out, and it worked for him; we logged back into my account and it still did not work for mine.
    Any ideas?
    Thanks for any insights.

    Indeed Trevor, that did solve the problem. Clearly it was something I changed... wish I knew what. But, I have a list of all the settings changes I made before, so I can figure it out by making one at a time then checking...

  • Hue/Saturation Adjustment Layer

    I am a Photoshop beginner working on a class project.  In the Hue/Saturation adjustment layer box, what number value will give me a "cool blue" for the Hue slider?  Thank you.

    "Cool blue" is as specific a color as "Yummy Purple". Wikipedia took a shot at defining cool blue here:
    Cobalt blue - Wikipedia, the free encyclopedia
    which it displays as this:
    and your sliders in Hue/Saturation set to:
    H20 S0 L34 will put you in the ballpark.
    I suggest that when it comes to color spec you familiarize yourself with the Pantone Matching System, for starters.
    Good luck.

  • Hue/Saturation Adjustment Layer Bug in Photoshop CS6

    I noticed that most of the time I cannot copy a Hue/Saturation adjustment layer in Photoshop CS6. (In about a third of all cases it works, in all others I have to create a new Hue/Saturation adjustment layer).
    Hitting Command + J will cause my Mac to make an error sound.
    Option + delete also doesn't work half the time.
    Also: I cannot do a "Stamp visible" above a Hue/Saturation adjustment layer. Hitting Command + Option + Shift + E will bring another error sound.
    I have to creat a new layer, and then create a stamp visible. But half the time this doesn't work, either. Hitting Command + Shift + N will give me another error sound.
    I have to create a different adjustment layer, then an empty layer, and only then I can create a "stamp visible".
    Only Hue/Saturation adjustment layers are affected by this - but it's a true hold-up.

    What Mac? What version of OSX? That aside, your issue sounds too exotic to be a genuine bug. Sounds more like some specific combination of settings is preventing this. could be anything from blending tricks to color profiles...
