surfing around the Web I've read several advices on how to set Level's Black & White values. I mean Levels, double click on Black and White eyedroppers ->RGB-> Black values 10? 5? White 250? 255? Which are yours?
View 3 RepliesBest practices for setting up systems in a lab environment. We have a lab enviroment of about 200 systems that access AutoCad, Inventor, Mechanical and others.
We need to have a customized interface come up when Autocad is opened by students.I have read that you can do this with profiles and workspaces and also with loading a acad.lsp file.
In the past we have just copied the Windows admin profile used to customize AutoCad to the default profile. In AutoCad 2013 that does not seem to grab everything. It doesn't seem to be the best way to do what we need.
We will also be moving to Windows 7 soon which will also cause an issue.I want to find the best way to do this with out having to deal with the Windows profile.
I can no longer adjust levels. I go to Layer / New Adjustment Layer / Levels and get the box that says "New Layers" and asks "Name" (Levels 1) "Color" (None) and "Mode" (Normal). No changes here.
I click "Ok" and instead of giving me the box with the histogram, it adds a layer to the Layers Control box and gives me an eyedropper with instructions "Click image to choose a new color" If I click on the image, it changes the foreground/background colors but nothing in the image. I can't get out of this dialogue without closing the application using the Windows Task Manager.
Is this a bug? A setting? - I've changed nothing on my computer...
With a photograph, is it best to clip the histogram or not?
In auto levels it does clip.
Or isit better to alt click whilst adjusting black and white points? Then back off just before clipping?
I have a situation where my image is 'faded' from left to right.
The left hand side of the picture is 'not bad' (but could use a little touch up). As we progress to the right the image becomes lighter and could use more and more touch up.
I've tried selecting narrow vertical adjacent rectangles and using the levels tool (to greater effect as I moved to the right). I suppose that with enough time and patience (and narrow enough selected rectangles) I could come up with a consistent colouration across the face of the image but---!!
So, is anyone aware of a plugin that would provide a gradation of the effect of the levels tool across the width of the image?
Or of some other way to clean this image up?

View 3 Replies View RelatedWhat is the difference between levels and curves?
They seem to do about the same thing when I play with them.
I want to reduce the colour levels in a picture to four, or limit the amount colours of an image to 4 colours.
I have many black and white images and I want to remove all but 4 scales of colour so that I have
White
Light Grey
Dark Grey
Black
The closest thing I have found is in the filter gallery bu using cut out and reducing the number of levels to 4 the problem is this tends to blurr some of the details as part of the effect whereas I want to maintain the crisp edges of my image so that it just looks flatter
I would also like to know if there is a method to do this and have it somewhat scaleable so I can decide on the range of colours in the current image that would fall into each of the new colour categories so that I can adjust itcase some details are incorporated into say the dark grey layer and they should be black ect?
I'm sure I have seen a very simple feature to reduce the colour range of an image, maybe that was in paint shop pro it was a long time ago.
I am losing my levels adjustment when converting from PSD to any other format here is the list of it...
levels layer...........taking the contrast way up
saturation layer....saturation up
invert function
find edges layer
duplicate layer
background layer
At the point that I convert to jpg or another file type I lose the levels adjustment. Also flatten image or merge visible layers causes the same problem. I can supply a file if needed.
Ever since upgrading to CS6, when I click Levels>Load preset, I can no longer search in the window for the file. Previously, I could type in the file name and it would come up and I would select it. Now, when I search for the file name, there are no results at all. The file can be found by doing a regular search in a Finder window, but not through the window that comes up from the Levels window. I've reindexed Spotlight, and that has had no effect. The workaround is to open a Finder window, search, find the file, drag the file into the Levels' load window and select it there.

View 3 Replies View RelatedI have a 3d render that has some semi transparent areas (shadows on matte objects) I want to get rid off. In AE a can simple adjust the alpha levels and set everything under 25 to be 0 for example.
In PS the entire alpha channel seems to be out of reach.. it's not in the Channels tab? I can add one but PS fills it with an B&W version of my RGB image.. What trick I'm a missing here?
How do you create a perfect alpha from this image, channels don't work, selections don't work either very well. I haven't done something like this for a while, so maybe it's a brain fart, who knows

View 3 Replies View RelatedQuestion 1: If I create two levels layers and, adjusting the center slider, I enter 1.5 of lightening on one and .5 darkening on the other, and then flatten the image do the two equal and opposite adjustments cancel each other without altering the image?
Question 2: Assuming the answer to Question 1 is yes, there's no alteration to the image -- if I adjust the first to 1.5 and the other to .6 does this create the same effect and using only one layer with an adjustment of 1.10?
What is the main difference betweem levles adjustments and curves?
Booth of these adjustment layers do the same in differnt ways:
contrast corrections, midtone correction, shadow/highlight corrections, color correction.
I understand curves allows to select secific tonal points in the image.When should levels be used instead of curves?
Is it possible to set specific opacity levels from 0 - 255? I want to be able to make a gradient with specific gradient jumps similar to this:
0
51
71
87
100
111
121
130

I try to apply Levels & or Brightness & Contrast settings to an image, it always seems to revert back to the way it was. The filters won't do anything it seems. I have Adobe Photoshop CS2. At home it did the same thing and I re-installed Photoshop only to find out it still did not work.
View 4 Replies View RelatedIn regard to using the three eyedroppers in the levels dialog box. I am crystal clear on how to most accurately find the lightest and darkest areas to click on with the white and black eyedroppers.
Its the middle one that I need help with. I have been told in the past that I should click on the area that SHOULD be gray, rather than what IS gray. Is there a little more of a precise way of arriving at which area to click on rather than just guessing like "Hmm, I think maybe his pants should gray".
Or what about when an image has nothing whatsoever to do with any gray. I know this middle eyedropper may not be critical, but I just gotta think there is a better way to do this rather than guessing. If a photo has just red, blue, yellow, green, pink, orange & gold, what "should be" the grayest? Obviously there is something I don't understand about this tool.
Levels and Curves. I'm trying to figure out how to give photos the sort of bright, colorful, slightly orange-ish glow that you see on this website... if you look for the color photos.
View 2 Replies View RelatedTo me, an easy and non-subjective way to make an image color-neutral is through Levels.
I leave the RGB channel untouched and use strictly the separate color channels (ctrl 1, 2 and 3), adjusting the black and the white sliders so that the blanco parts (non-information) on the edges of the histogram are excluded.
I was wondering if there exists a shortcut for this, since it is a verifyable action based on concrete readings. When scanning a large amount of images, it seems unnecessarily exhausting to repeat this action time and again.
The Auto Levels or Auto Colors commands don't work subtle enough, because they usually discard the outer parts of the histogram.
Using Photoshop CS3. I am trying to adjust the levels on a very simple bitonal scan from PDF. When I adjust them by going to, Image, adjustments, levels, the preview of it works and it shows what I want, but when I hit OK, it dissapears. If I go to Layers, New Adjustment Layer, Levels, it shows up fine until I save it.. I am trying to save it as a PDF file, and I am saving it with Adobe 6 (1.5) because of compatibility issues (so I've read), it should save layers. But its not saving. Or maybe it's not opening in my Adobe Acrobat? is there an update I need or something? Is there a step I am missing? is anyone else having this problem? Even so, the Level adjust should work regularly while in PS CS3.
View 1 Replies View Relatedbasically what is happening i am importing line drawings that i have scanned in. i am opening the TIF file then changing it to a PSD or JPG (i have tried with both) changed the mode to RGB and 8 bit
i then try to adjust the levels of the image to make the drawn lines i scanned in stand out more. the preview shows the lines getting darker but when i click "OK" the image just doesn't change and the lines stay faint. the same happens when i try to use just the simple "adjust brightness contrast" option aswell. is there something i can do? i cant seem to figure it out!
Why does elements when I adjust my level to get a darker image the photo reverts back to the original lighter level
View 3 Replies View RelatedI have a levels adjustment layer and I want the opposite of this, so I want to invert it.
View 3 Replies View RelatedIn CS3 I use a Dust & Scratches filter on a layer in a high resolution (3200+ppi) 16bpc image, then traditionally change the layer blend mode to Difference, make a duplicate of a channel which has the clearest information of where the filtered changes were made, and use levels to increase the contrast on a copy of that channel. Occasionally I get this result though - the Levels adjustment preview shows spots clearly, but clicking OK results in something very different from the preview. This only seems to happen occasionally.and result looks like this:
As the purpose of the channel is to make a mask, the result isn't as good as I'd like. I assumed that the problem might have been the grey starting colour of the channel, so I pushed the 0 up to 9 in an attempt to get a uniform K value of 100% on the darkest areas, and then ran a second Levels adjustment to make the white spots brighter. The second levels adjustment resulted in pretty much the same result as above, again, not what was shown in the preview. I also assumed that it may be down to numbers and that levels is occasionally too limited to deal with all the shades of grey on a 16 bit channel. Probably wrongly as this normally works exactly as required.
This only happens occasionally, and isn't that big a deal - I can quite happily go and use a Curve instead. I'm just wondering why the preview in the adjustment window is different from the actual result. The fact that it only happens on some of my images is what concerns me - purging all beforehand does not make any difference.how to get accurate results in the preview? Is the preview using a different method to show the results? Unfortunately I won't have a copy of CS6 to try this on until a couple of weeks from now, so not sure the best way for someone to try and replicate it on newer versions.
I'm taking shots of some furniture I made. I get the shot all set up and the exposure correct for what I want, then I take an 'extra' shot with a gray and a white calibration card in the scene. Now I have two identical shots except that one has the calibration cards.
My question is: how to I select the white (and gray) levels from the calibration shot and then use that data to set the white (and gray) levels in the good shot. I had done this many years ago in CS3, but I don't remember the process.
