Color range HELP #2

OK - I guess I need a little more guidance with the specifics of the step-by-step - do you have time to explain a little more in detail? Many thanks again, it's greatly appreciated! Original post below:
I need to change the color of this boat hull from blue (which is very monochromatic, solid blue) to a sage green (also attached for reference as per client request) and I'm having a really hard time with it. I need to be able to maintain the reflective nature of the paint on the sunny side and subtle shadow variations, so can't simply paint it in with replacement color. Maybe a combination of desaturation in an HSL layer, and channel mixer or replacement color in some way? At least it's easy to mask...
A Curves Layer to edit the luminance and a Solid Color Layer set to Blend Mode Color might help, both in a Group with a Layer Mask.

As basis for the Mask I actually used the a-channel of a copy of the image in Lab-mode, which I edited with curves and painted out the regions that exceeded boat and reflection.
This is used as a Layer Mask on a Group that contains a Solid Color Layer (af a desaturated green) set to Blend Mode Color under which I put a Curves Layer (set to Blend Mode Luminance) to lighten the affected regions as they appeared faily dark otherwise.
Switching to 16bit might help if banding becomes noticable.

How do I select a color range like in Photoshop OR copy/move a layer into the mask of another layer?

Hi there,
I'm trialling Photoshop Elements and wanting to use a black and white (grey scale) layer that I've made as a mask in another layer and don't know how to do it in Elements. In Photoshop, I'd do this (there maybe a better way in PS to do it, but I haven't discovered it yet)...
Click the layer i've created that I intend to use as a mask
Select All
Copy
select layer that I want the mask to be applied to
click the Add Layer Mask button (at the bottom of the Layers window)
click the mask icon so it is highlighted (and the image isn't)
switch to Channels view
highlith the Layer Mask beneath the R,G,B layers and make it visible
Paste
make it invisible again
switch back to layers.
This works and retains the full range of transparency for semi transparency and soft edges of the mask etc.
Alternatively, I can select a Color Range, but that doesn't seem to be available in PS Elements.
So, how do I achieve the same result in PS Elements?
Thanks for your help

Perfect! Thanks very much R_Kelly. That does exactly what I was hoping to do.

Color Range doesn't work properly in CS3

Hi there,
I have a problem with CS3. Since a few weeks I can't use properly "Colour Range" feature.
Especially for bright colour the Colour Range doesn't select what I want to select. For example I want to select a bright cloud and can't select it with Colour Range. Of course I checked if there is any information or I have a burn area.
I use several different setting but I still have the problem.
I used 8/16 bit, Adobe RGB/sRGB
At Colour Range I use:
- Sampled colours
- Selection
- Fuzziness: how much I need it
- Selection preview: None
I need help...
Thanks

Possibly you are missing something in the way you apply this command. Here's how I use it to select patchy clouds with ragged edges and continuously varying shades of gray:
Select the eyedropper tool on the Toolbar and on the options bar set the sample size to 3x3.
Activate the Color Range command. Activate the "selection" radio button and choose "none" in the selection preview. In the "select" box, choose "sampled colors".
Set a trial fuzziness of,say,50. Click with the eyedropper on a point in the midst of the color you want to select. That's your "base" color.
Then switch to the "Color Added" (plus) eyedropper, holding the left mouse button down while dragging it over areas deviating from the base color but which you want included.
If there are non-contiguous areas with still different colors you also want to include, release the mouse and move the cursor to those areas before dragging again.
All the while, keep an eye on the dialog box display which shows what you've selected, albeit crudely. If you pick up unwanted colors, switch to the "subtract from sample" (minus) eyedropper and drag it over those areas.
When you think you've got it about right, experiment with the fuzziness slider to see if you can improve things by increasing or decreasing fuzziness.
Don't re-use the plain eyedropper unless you want to start all over again. Optionally, instead of switching among the 3 eyedroppers, you can activate only the plain eyedropper but use it with SHIFT to add or ALT to subtract.

Color Range "Local Group"

Hello together,
I just wonder what the new feature within the Select: Color Range Dialogue means.
I'm using the german version, so I don't know how it's named in english, but it should be something like "local colorgroup". It's the only new feature in this dialogue.
So, what exactly does this feature? i tried for some time but I can't figure.
As far as I thought in the beginning I can reduce the selected color values a bit more smooth in adition to the tolerance-bar.
But than, sometimes, after checking the box for this feature, my selection gets twice as big as it was before?
Can anyone help me out of my misery. :)
Thanks a lot
Philip

From what I can tell, it seems that the function will be more tolerant the closer it is to the click point.
In other words, it's kinda of like a radial gradient spanning out from the point that you click. It will select more for the area closer to the click point and gradually less as it moves away.
This may or may not be what it does, this is just what I have found from fooling around with it.

Is there a color range function in PSE

I have used photoshop CS4 and been comfortable using the color range function. I have tested PSE which I am thinking of buying as it is more affordable, however could not find the color range. Is there a similar function or is it got a different name in PSE? I mainly use this for jewellery and to change backgrounds.
Thnaks for your time and feedback.

did it happen to you?
is there a cure?
thanks

This has been happening to me today only. I have been using this program for about a year now. Today I duplicated a layer, went to select at the top, and selected "Select Color". I selected a lot, most of the image, then when I clicked "Okay" it crashed. I did this several times and it persists. I remembered to copy the error thingy one time and it was this:

I don't have any plug-ins and when I went to look at the files listed, I opened WER3D6E.tmp.version.txt. But when I closed it, neither it nor the other two were there. I'm guessing the .tmp means they're temporary and I was only able to open that one because I did it so soon after the crash? Anyway, I came to these forums and saw something about MM fonts - I don't have any. I also saw people with this problem - color select. So, I opened CS5, duplicated the layer and before I could click "Select", it crashed. I forgot to get the report    but I got this:

Photoshop CS3 Color Range Problem

I am having an issue with the color range selection tool in Photoshop CS3 on an iMac G5 running Snow Leopard.
I've been using this tool for years and it's always worked properly until now. It no longer selects the color I've picked with the eyedropper. The only time it works properly is when I set the image to grayscale mode. In any other mode, it selects erratically, like the image below. Those are clean rectangles I created with the paint bucket, so I'm not sure where the lines selected in the Color Range view are coming from. Adjusting
"Fuzziness" doesn't help. The image is set to 8bits. Any ideas?
I've tried using the color range on another computer with the same settings and it works fine.

Is the Eyedropper Tool set to Current Layer in the Options Bar?
If nothing else helps you can always try trashing the prefs (after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed).

PS CS5: select color range not working properly

The color range is a grate command but it doesn't work properly when dragging the eye dropper across the image. This is especially noticeable with a low range value. When you start the selection (without pressing the shift key) and drag across the image only the end point is selected instead of the whole trace. Second, when dragging with the shift key pressed not the trace is added to the selection but a rectangular area. You can easily try this out by creating any one color image and lower the range value to about 5.
In my opinion this is a bug or am I missing something?

Hello,
When you start the selection (without pressing the shift key) and drag across the image only the end point is selected instead of the whole trace.
This behavior is as designed. When you make a selection without holding the shift key, and you have the first eyedropper selected in the menu (the one that doesn't have a plus or minus sign) you are a making an initial selection on the image. If you hold and drag this selection, it will just change the initial selection to match whatever destination you prefer on the image.
Second, when dragging with the shift key pressed not the trace is added to the selection but a rectangular area.
I can reproduce this behavior, too. I believe this is also as designed, because the range is too small to make an organic looking selection. I think the more standard workflow is to start with the range high (100%), make the selection of the localized color area you want to mask, and then reduce the range value as needed.
Color Range isn't terribly intuitive to me, but it can be a powerful selection tool. Photoshop Evangelist Russell Brown has a really good tutorial on Adobe TV about using color range. Have you seen this before?

Giving a component with incremental color range in CSS

i can achieve this using a similar type image as background,
but i need to know is that possible in CSS.
Pls help me out with related discussion or topics.

Hi!
If I want to do a selection through color range using selection with highlight tones for example i can't control the tolerance.
I'm using the 14.0 x64 Photoshop CC version on a mac. Scripts are not the point really. See my screenshot (sorry its in french!) i can't control anything.

Color range selection + layer styles

Hello--
Help me if you can!
I have had it on good authority (my photoshop instructor) that color range selection hasn't been working correctly for some time.
I'm using CS2, version 9.0.2 on an IMac os X version 10.5.8.
I am often working with multiple layers that are not similar at all. When I have one layer active and do a color selection, it may also select the color range on inactive layers. Then, if I do a fill, for example, it may affect areas on other layers that were inadvertantly color selected. I know there are ways to ask photoshop to perform a function on all layers, but I don't see this as an option or setting with color range selection. I had started to assume it was sort of like crop, which affects all layers, but when I asked, my teacher says it should only be selecting/affecting the layer that is active.
I found I can deal with this by 'closing the eyes' (making non-visible) the other layers...but that is a hassle and sometimes hides exactly what I need to see.
Then noticed, just lately, that when I use a layer style, it is no longer showing up on my layer palette. Maybe I don't understand correctly, but I thought any layer style addition would show up on the palette under the name of that layer. If I happen to remember that a particular layer used a layer style, I can still click on the layer styles icon and alter it, but it isn't displaying on the layer palette any more--so I cannot toggle or discard the effect simply, and it is hard to know why a layer looks the way it does without that information.
Could be I'm corrupted and need to deinstall/reinstall? Is there something I'm missing about these functions , or something I accidentally changed? I would really appreciate any help or information.

Yes your instructor is wrong, it always selects visible pixels, and always has. You can however create a selection before you go into Color Range, and it will only work within that selection though.
If you want Color Range to work in precisely the same way as it always did in the old versions you need to make sure that you ..
• Highlight a non masked layer and
• Uncheck the somewhat bizarrely entitled "Localised Color Clusters" checkbox
The changes to Color Range happened a few versions ago, to my memory it was with CS4 . The main improvement was that they made it more powerful with the capability to produce better more refined selections. They also unfortunately made the daft mistake of making the command work DIFFERENTLY depending on whether you have a masked or a non masked layer selected. This is not very logical really because it just causes confusion, and doesn't really achieve anything constructive in my opinion. No one who knows what they are doing wants to modify an existing mask using Color Range.

The Color Range command is the best way to make a color-based selection. Build and adjust your mask and then use it to apply localized changes to your image.

Select Color Range not Working

i have been using adobe photoshop for over 10 years and suddenly, when i try to select color range, nothing is showing up as selected. even with a simple black and white image, with white or black as the sampled color, nothing gets selected. i don't if something changed in the application or if it is somehow not working correctly on mine. please help.

Hi,
What version of photoshop and operating system are you using?
Nothing seems to be selected in the preview or when you actually exit color range?

Adjusting Bitmap color range

Hello everyone
I am currently using Labview ver 7.0. I currently have a bitmap picture of an AutoCAD drawing that I would like to edit programmatically. Basically I have some temperature sensors on my hardware and I would like to add a color range to a specific spot on my bitmap image. The way it would function is that as the temperature increased at the sensor, the color of that specific area in the bitmap would change color (yellow to red or something)
My thought right now is to possibly try and accomplish this with either custom shaped color boxes, or by creating sections on my drawing and being able to color each section separately (similar to how you can section a picture for website links).
The picture contains sections that a
re not square so a custom shape is best.
If I have been unclear or feel I have left something out please contact me and I will try to be more descriptive. Thanks
TK

This is an example of how to draw colors onto an image. it is very crude but you get the picture. HAHA. seriously. I think this will point you in the right direction. you can find everything you need on the grapics and sound pallette.if this does not help repost your question and I won't answer it.
Sorry I could not be of more help.

Color Range Selection using Lab values

Is there a way to select pixels in Photoshop based on given Lab values? I am using Select --> Color Range with a specified "fuzziness" threshold, but I'd rather make the selection based on specific Lab values instead of random pixels that I choose with my eye dropper. Is there a way to do this in Photoshop, or does anyone know of a plug-in that might do this?
Also, if I end up having to use the basic Color Range tool, I'd like to know what "fuzziness" means. I understand what it does (selects more or less colors based on the threshold around the point you choose with your eyedropper), but what is that based on? A color difference (delta E) value around that point maybe?
I am using Photoshop CS3 v10.0 on a Windows XP machine.
Any help would be greatly appreciated.
Thanks, Ellen

It may be helpful to compare the Color Range command with the Magic Wand Tool. A Magic Wand "selection" is 100% opaque and all pixels outside its tolerannce have zero opacity. So the selected pixels are either totally selected or totally unselected. There is no partial selection.
Not so with the Color Range command. The pixel clicked establishes the "base" color. Whereever that exact color occurs in the image, it is totally selected (100% opaque). The degree to which other pixels are selected (their opacity) depends on the Fuzziness setting.
At zero Fuzziness, all pixels other than those with the base color are totally unselected (zero opacity). As the Fuzziness setting increases, pixels with values other than the base value begin to be selected, but not 100%. There is a bell-shaped (Gaussian) curve of opacity centered on the base value and dinminishing on either side of it.
The breadth of the Gaussian curve (let's define that as the color value difference between 50% opacity on the left and 50% opacity on the right is directly proportional (not equal to) the Fuzziness. Double the Fuzziness and you double the breadth. Marching ants appear at the 50% opacity point. But be careful interpreting this because with the Magic Wand, for example, the 50% opacity point occurs at the same point as zero and 100%, there being no gradation of opacity at the edge of a Magic Wand selection.
You need to be aware also that the Color Range command operates in each color channel and the deviation from base value is determined by the most restrictive of the three channels. If a pixel is within Fuzziness limits for one channel but not another, it doesn't pass muster. And, yes, CR uses Lab colors, but you need not be in Lab mode.
