Photoshop :: Matching And Comparing Two Colours
Oct 7, 2008
I need to compare and match two colours but dont know how to do it exactly. the scenario is; I have two samples. Sample A is the reference, and Sample B is a trial. The trial sample is going to be very close to the reference, but not exactly the same colour.
What I am going to do is scan both samples on a scanner and then compare them. I need to find out what colours do I need to add/remove from Sample B to make it exactly same as Sample A. That is the most important bit; need to be able to understand which colours missing or needs to reduced.
Samples are one uniform colour but ideally need to get 3-4 sampling to get the average colour from each sample for accurate results.

When I use Photoshop CS3 and paint fast strokes with a brush they update in real time. But when I do that on the same computer in Photoshop CS4 with the same brush size I have to wait a lot after I draw for my paint strokes to update. It is so slow that is simply impossible to work.

I use gimp to make layered stencils for spray painting...I reduce it to a couple of colours, seperate the colours into different layers and then cut them out...
When I do im left with a ghost type image where the original layer was..
example: [URL]...
Is there any way of avoiding this?

is there any way to compare ctb files? I know there is a tool called tableprint9.exe that will export the ctb as text but it is not working with Autocad 2010.
Is there any way to access ctb files in .Net?

We're trying to perform a shadow impact study in NYC. We have imported the existing buildings and topography and run a shadow model with these features. We have done the same adding a new building to the model. We now need to quantify and compare the incremental shadows cast by the new building in addition to the existing shadows. Is there a way to assign a color to the shadows cast by the new building to differentiate these shadows from existing conditions?

Is there a way to have side-by-side two images from different folders? Say, one from 2008 and one recent? Lightroom 3.6...

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?

We will be doing some grading in a park with trees. Probably maximum depth or fill of 12 inches. The question has come up to be able to show cut and fill quantities as a visual shade of colors. I have a way to display cut and fill ticks and it will give me the value, but that's not what they want. I change the cut ticks to red and the fill ticks to green. What is the best way to represent this like when you turn on slope percentages and assign different colors. but I want like 0-2" fill to be red, 2" - 4" to be green, etc.

It takes a list of Parameters and cycles through the assembly looking for parts with the same parameter names. It then copies the value of the parameter from the assembly down to the part.
It occured to be that this would be more efficient if I didn't have to manually create a list of parameters to compare.
What I'd like to do is create a list of all parameters in the assembly file that begin with the prefix 'A_', and compare this list against the parameter list held in each subassmbly and part file in the assembly, copying the values down as before.how to build the parameter list?
' set a reference to the assembly component definintion.' This assumes an assembly document is open.Dim oAsmCompDef As Assembly Component DefinitionoAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition'Iterate through all of the occurrencesDim oOccurrence As ComponentOccurrenceFor Each oOccurrence In oAsmCompDef.Occurrences'check for and skip virtual components'(in case a virtual component

I have a big hole in the ground in my model. Its easy to get the volume of cut with C3D. But I have a topsoil layer, weathered rock layer and then solid rock, I basically need to break them down into different volumes. The way I would normally do it is calculate the topsoil, then work out the weathered rock and minus the topsoil, then for solid rock cut I minus the topsoil+weathered rock. I have attached the 3 volumes I need for info.

i'm working on a job with 2 colours. I already did this using CMYK and setting 2 of them to 100% and the other 2 at 0%. But people who press these posters say me that they always have to convert the CMYK file to a 2 colours file. Is there a way to set my colours to 2 colours instead of 4?

I just downloaded CC and was able to implement my workspace from CS6 and load presets. But color settings and other preferences along with screen colors etc are not how I want them. Any way to match everything with my CS6?

Let's say I have two pictures. The first one is a RAW file and the second is the same file, but a flat PSD with some color and contrast moves done to it.
What I want to do is to (of course start with processing the RAW file so I have a PSD/tiff) and then I would like to match the colors to 100%.
Usually I would do this by eye, but I would like to find out if there's any quicker way to do it? I started to look in to the color sampler tool to get the different values.
Preferably I would also like to have all these color and contrast moves in layers if possible. So that I can adjust them if I want.
---------------------------------
The second question is basically the same but this time the reference photo is a different picture.

i'm into photoshopping cars and i've got a rough idea on how to stitch bits and pieces of other cars together nicely, the problem is i still haven't a clue on how to match the colours of different cars to my target car (i.e. my car is blue but the bumper of another car is green, so how do i get that green to match my car's blue?)
i just really want to know how to get this done cause previously i was using the luminance thinggy and found it to work for SOME colours but it didn't look good.

I have the font close although i cant seem to match it exactly. But the crispness from the copied image from the web i can not match. The copied image text is very crisp. I can not match it with Photoshop. Why would this be? It doesn't matter what Alias setting i use and i tried a ton of fonts etc...

Im working on a series of images from a photoshoot.
I am having massive problems with getting the background of each image to match with one another. Each image seems to have a slightly different shade background, so basically they all look inconsistent together.
Is there anything i could do which would easily match the background from the different images together?
Using curves doesnt really help and when i do get it right (slightly similar), skin tones are then off.
The photos are done in a studio and evenly lit, the backgrounds are pale blue!

How would i go about getting this picture:
to resemble the same type of contrast/tones/colors as this picture:
i've tried using the constrast tool, and trying different hue saturation settings and lowering the opacity, but nothign really turns out as good as the ludacris cover.

I have been working on a gag project that involves placing different co-worker heads on different bodies. However, I have been having some difficulty matching the skin tones. I thought it would simply be a matter of using the eye-dropper tool, getting some average values on the face and body, then using an adjustment layer grouped to the face layer to adjust the color.
However, my results are often not even close. Is there a particular way I'm supposed to be adjusting the color?

I am currently working on a series of images for a calendar. All the photographs are portraits and were shot against the same backdrop.
I am working in Photoshop 7 and having scanned the images and given them a clean they all have different casts. Is there some way of matching the colour of one image to another, rather than attempting to do it by sight and botching it up?

1)When I view the same raw file with both Lightroom 2 & Photoshop CS3 the PS version is darker with a slight colour shift. All metadata synchronised & ACR 4.5
2) When I export a photo (from LR)as TIFF (with profile) this same photo viewed on both PS and LR shows the same difference as 1 above. When same photo viewed with ADC pro, result matches LR not PS.
3) When I print photo (as TIFF above) with PS & LR the prints from both match the LR display and not PS's
I use a calibrated display.
What is the problem here anyone? Does PS use display profile differently from LR? which is correct?

I travel around the country and use Photoshop for various projects. I then SAVE AS a TIFF file to my flash drive and take the flash drive to an office superstore (OfficeMax, Staples, Kinkos,etc.) to print on their color printers. I run into a variety of printers, but mostly Xerox DocuColor 250's or Docucolor 12's.
How can I set my Photoshop so that the colors that print on these Docucolor printers are closer to what I see on my screen? I'm already creating the documents in 300DPI, CYMK-8 mode to be as close to the printer as possible.

I was asked to take the group photo, cut out the black girl, and insert the young man. See all images below and my results. the only thing I'm not happy with is the young man was better lit than the group one. I was playing around with the controls of the young man to bring his tone more in line with the group (hue; saturation; color levels; etc.) and I just could not figure it out.
what I can do to get the young man to match up tone wise with the group? Or vice versa, even?

I want to use Refine Edge to move a person from one image to another. That part I can do, however, once the person is placed into the new environment, I want to adjust the person so he looks like he actualy belongs in that image. I want to adjust the lighting, shadows, etc. Is the Levels Tool the best tool for matching lighting?
