Photoshop :: Color Correction Through Levels
Dec 28, 2004
To 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.

So I have an action that I've been using for the past couple years (?) now that involves opening an image, applying an auto color and auto levels, saving and closing. This has been working for me since probably a couple years ago when I made the action. Yesterday, I was working on a scanning project where I have groups of images in separate folders. I ran the action on the first 2 folders which went fine.
When I got to the 3rd folder all the way up to the last one, PS just loads all the images, does the levels and color then fails to save/close them when done. On one of my folders, it gets through a few of them when it drops the ball and just opens all of them. I'm not sure what's going on as there's no real explanation as to why this is happening.. especially when I've been using this action (and I even made a new action with still no luck). Last week I had about 300 images I had to work with and PS decided to pull this move on me after doing the first 30 of them fine...which is when I first noticed this happening.
Â
To further add, I set my action to show everything step by step and it seems to happen with select images (in some cases, these select images are entirely what is in the folder). With the select images, it is not doing the actions entirely in order. Typically it does it in this manner:
1-Levels
2-Levels
3-Save
4-Close
Â
What I'm now experiencing is this:
2-Levels
1-Levels
(Skips 3 and 4 since it is starting at 2 and working upward).

I am taking pictures of art and would like to correct the photos so that the colors are accurate. Need to use some kind of color swatch in each picture? I would like to include the color swatch strip in the edge of each picture so that I can correct the colors more easily and then crop the color swatch out. What kind of colors do I need in the color swatch? Also, would it be useful to have black/white/50% grey in the strip to work with leveling? I am going to correct the leveling and try to remove the color cast.

I also have to photograph things which are very shiny (e.g. coated in shellac). How to use an external flash to minimize flash glare?

when you move it to PS he has you use the curves panel to color correct. Of course that entails using the black eye dropper and clicking on the blackest/darkest area of the photo, similar for the white dropper, and after a nice little trick to find the right spot......... an area for the midtone dropper.Â
Â
The thing is I've noticed that once I make that first click with the black dropper, that nice contrast I had from ACR adjustments goes out the window and the photo brightens up a lot. The final steps of putting 3 points on the curve and dropping the blacks end and raising the whites end brings it back a bit but I was thinking isn't setting the WB with the dropper in ACR already color correcting?Â
Even at the end of the book when he goes through his actual workflow using a provided .dng example he does all the ACR stuff and then moves to PS and uses the curves panel.

I want to display photos shot as JPG from a DSLR on a TV. When played on the TV they seem dark and lots of detail gets lost. How to make my images look good on a LCD TV? I am pretty new to Photoshop, would I just play with the Levels?

I am interested in which method to use to correct color. I try using curves and end up with a blown color look. Then I go into Levels and change what I did in curves.

In PS 7.0. I have a brochure done by a printing company & I have the source photoshop files. I am creating a new piece, but I would like the brochure's background color to match the background of the new piece.I have took the background file of the brochure provided by the printer & placed it on the new piece. The new piece has been sent out to a different printer. It's stock is going to be 18PT.C1S with high-gloss film lamination.They have printed a proof & realized the background colors do not match. The brochure has more yellow in it. Is there a way I can color correct the file so I don't have to pay the extra for the printer to do it? Do I just add more yellow with one of the adjustment layers?

I am taking photos of parts for a client. I've got a pretty good method down with correcting the originals to achieve the results I need. First here is the original. I'm using different color temp light sources, the walls of the photo box are slightly gray, and the table the parts are sitting on are white. So i'm trying to achieve the most accurate camera settings to get the original below:
Â
After doing levels and exposure correction in PSD, I get what I want. I played around with the channel mixer and color balance to see if I can properly correct the object so it looks like gray steel, and not having that slight yellow/green tint to it.
Â
 The only way I could figure it out is to just turn off the hue saturation and it gives it a somewhat decent result as seen below: But suppose my object is made of gold, or has a piece of plastic on it that's red; if so, then turning off the saturation will not work.how I can use other controls in PSD to achieve a more accurate result?

I took some family portraits using a Canon D60, RAW files.
I'm using Lightroom and Photoshop to work on them, with the goal of making a hard-copy print.
Also, I used florescent photography lighting, with "6400K" bulbs that came with the lights.
My problem is a little yellow tinting in some of the skin tones. My face, for example, looks just fine except for the shadow areas around the eyes, where it seems a little yellow-green, looking almost like a bruise. Meanwhile, my nephew's face looks a bit yellow.
I've used (in Lightroom) the neutral eyedropper on white clothing and grey background, and everything else seems fine. That is, the photo is not over-all tinted. I've tried the different Camera Calibration settings, and tried the temperature/tint sliders to see what difference it made.
How I might improve my photos? I've attached a detail, saved with an ICC profile of AdobeRGB.

How do I make a selection of ALL the yellow on the Meatball building and make it a deeper yellow the way it has been done in the attached photographs:

Someone suggested playing with the Color Range: Select/Color Range and then use the lasso tool plus the option button to delete what you don't need. But that's not working for me.

And in the next photo, what is/how do you achieve the blended effect on the area that is the where you would more obviously see that this is made-up of two photos? It's a blending mode right? Which one?

If you had to recommend a "color correction" plugin, which would it be?
I'm assuming that most you use PS's native tools for the most part but have a couple color correction plugins you think actually work...

I clicked on the auto color correction from the level because the picture was pink. I looked at the shadod clip .50 , highlight clip .50 and closed it when It changed the picture and it's better now but Can I still use the arrow from red, blue and green from the level to get better pictures?

I used to have Photoshop 7 and often used the RGB controls to make color corrections. Now I have Elements 8 and I miss having RGB controls. Is there a way in PSE 8 I can simply adjust R, G, and B individually like I've been used to?If not, what is the closest substitute in PSE 8?

whenever [on any photo] i apply auto levels or auto contrast or auto color from the image>adjustments tab, the entire photo will completely white out as if i had added a new white layer over my active layer (which i am not doing). however, it only does this in 'auto' changes. so if i were to manually adjust my levels or my contrast or color, the 'white-out' effect wouldn't occur.
i really need this feature. i have already uninstalled/reinstalled photoshop cs2 and that didn't seem to fix the problem.

Gradient and color banding are very apparent and exaggerated until I zoom in to 66.6%. It even hangs for a split second as if it is solving a new render at a higher quality. This is getting frustrating as I've found myself manually trying to clean up issues that actually aren't there when I zoom in close enough. These issues are expecially obvious when working with skin using several degrunge techniques and dodge and burn on a softlight layer. It does not seem to matter what display I use.
Â
If I commit all adjustments to a new layer the problem goes away. I'm working on a Eurocom Panther 3 running Windows 7 64 Ultimate. I have a hex core Intel processor and 2 Nvidia 580m in SLI, though I am aware that is not used in Photoshop.

I entered the following key sequence: Adjustments Panel | Levels | Alt-Click Auto | Find Dark & Light Colors | Snap Neutral Midtones | Midtones After keying in this sequence and making adjustments to my photo, I inadvertently hit one too many OKs as I was exiting and PS changed my defaults. They now read: H: 55, S:0, B: 0, R: 128, G: 128 and B: 128. How can I reset these values to their default settings?

When I try creating a color balance adjustment layer is it opening a levels adjustment layer. I'm using the New Adjustment Layer button at the bottom of the Layers panel. Is this a bug with CS6? How can I fix the problem?

I cannot get a color balance adjustment layer to come up. Every time I do photoshop creates a levels layer. Selecting levels makes a levels layer. All of the other adjustment layers seem to be working normally.
How do I fix this? I have a deadline and no time to be reinstalling photoshop.

I have a set of photos, taken a while back. They're closeups of the stages of a craft process, and not easily reshootable.
I was with the craft, I didn't notice that the day was passing, and that the light I was shooting with was varying, and I didn't do a manual white balance for each shot.
Each photo on its own looks "OK", but when I tried a montage, the white balance differences between the shots was UGLY.
So - I don't need accurately calibrated shots, but I'd like the colorspace of all the photos to be as similar as possible, so that identical physical objects have the same in-image colors.
There are several areas in the photos that are of the same (physical) item that could be used to drive a calibration/matching process, but they're not white/gray/black.
So - how do I match up the colors? I've tried to botch at it by hand editing curves but it was tedious and error prone.

I've been learning After Effects for several months and I have to say its a blast. I'm already in projects where they require special effects, and from months of just teaching myself.I'm almost finally able to achieve any effect I want, for example: a bomb made to implode the earth's core with a black hole (a still picture from an upcoming super hero comedy series called "Zack").
Â
Anyways, I'm now learning more advanced color balance, I always knew the basics and I just go with what looks good (which is how it usually works), but I never quite understood. Like curves.I watch tutorials and see people use a mix of colors to get the color they want. Honestly I don't know my colors in that way, is there a chart guide for color correction?

When I use the eyedropper to build a secondary color correction mask (rgb curves, three-way, etc) I have to click the eyedropper with the + and then go over to my source monitor and click on the portion I want to build the mask for. If I need to select multiple colors to dial in the mask further I have to keep going back over and clicking the little eyedropper + and then back over to the source monitor and back and forth over and over again.
Â
I know there is a better way, or at least a short cut to reselct the eyedropper +
