Photoshop :: Grey Scale Conversion In CS5
Nov 30, 2012
I've found a peculiar problem with grey scale conversion in Photoshop CS5.
The problem:
I have black and white photos in an RGB colour space. I can't use a black and white layer adjustment because there are no color channels in the image. I used the 'image > mode> greyscale' menu item to convert to greyscale, and in photoshop there appears to be no change to the greyscale values. However, when I place the image in inDesign, it is markedly different; blacks are pure black but greys are washed out.
I print the two images side by side (RGB and greyscale) and they come out identical (though darker than I expected). Is inDesign showing RGB or Greyscale differently on screen? I have the display settings at 'high quality'.

the current raw converter in LR5, Bridge CS6 and Photoshop CS6 produces magenta or green pixel errors on grey ridges (e.g. mountain structures).
In Nikons NX View 2 does this problem not occur.

I have recently installed PS7 on my laptop and when creating a new project, the defaul is sent on grey for the color, when I set it to RGB or CMYK and want to choose a color, I get the standard color box with about 20 colors instead of the color pallet I used to get.
What is the setting I'm looking for and how to I set it as the default?

If there is a way to tell Photoshop, and in a CMYK or RGB file, that I want to make all the 100% blacks in a grey scale layer a solid specified color, and all greys just percentages of that solid color? And to be able to do this without having to use spot channels or dial in CMYKs via Channel Mixer? In other words, a "one-click" method, or close to it.

Is it possible to use .png grey scale photo edges (made for photoshop) in paint.net? I found some "frames" that will add various edges to the image (torn edge, lace, ect), but they are in grey scale and I'm not sure how, if I can, to use them in pdn. I'm just wanting to give a ragged or other style edge to my photos or backgrounds to use them for digital scrapbooking and framed photos.

I am trying to add a grey scale mask to a layer so I can alter some game files .But I must be missing something blindingly obvious. Here is how I create a mask in PSP6.
-First I duplicate the base layer.
-Then I adjust the saturation to -100%(grey). Then I adjust the lightness to +100%..This gives a grey scale image.
-I then increase the brightness by 25% and the contrast by 50%. This gives a grainy bright and high contrast grey scale image.
-I then create a mask and then add the mask to a blank layer.
This allows me to spray away to my hearts content and leaves the main detail on the original image untouched. By this method I can add mud effects to tank tracks in games and still see the original link details through the mud.
But I am having major issues trying to achieve this effect in gimp.At the moment this hurdle is stopping me getting to grips with gimp.

If I select a "New" document in CS5 I find that I am only able to paint or fill in in grey scale. This is new. In the Color options panel the grey scale slider is ticked and all other options are greyed out.
How do I remove the tick by the side of the grey scale slider and make the other options available for selection as normal. I note that if I open a previously opened document all options are available it just seems to be new blank documents.

I have just had to do a complete re-install of my CorelSuite X4 following the addition of a new hard-drive.
I now have the situation in Corel Photo-paint where -
1 I open a grey-scale image (.jpg).
2 I paste (as a new object) an RGB colour item (a previously created .cpt file) onto the grey-scale image.
3 I then "Convert to 16Bit grey-scale" in order to change the whole new image to grey-scale, but the pasted object is being automatically flattened into the image and I can no longer work on that object independently.
I never had this before, as I was always able to convert to grey-scale and the "pasted object" would remain with the mask outlined and still allow me to work on it.

I imported a photo into illustrator CC and I then live traced it and expanded it. When I select it the colour options are grey scale. I can change the option but if I click off the image the options go back to grey scale. The doc colour set up is cmyk. How do I get it to stay on a different option without having to keep switch it all the time?

as a user of pse 6 I 'm used to work with darkgrey background in the organizer.
This works perfectly for quickly assessing brightness and contrast of pictures.
In pse 10 however I could not find any button to change the preset lightgrey background colour to darkgrey.

I am currently running Map 3D 2012 with CadWorx and I am having an issue with one of my multi tab drawings. Any object set to plot grey (any grey), that is in paper space, is plotting black only in one of my layouts. similar objects in model space and in both spaces on other layouts are all plotting accordingly.

is it possible to create a gradient brush with the colors fading from black to white, and then edit the colors so instead of black fading into white, it's now black fading into transparent?
(so the pixels that were pure yellow are now completely transparent, the pixels that were slightly darker yellow are now almost completely transparent, the pixels that were dark yellow are now barely transparent, and the black pixels remain completely black.)
(I was only able to do it now because I started off with that black/transparent image)
I want to do this so I can change the color of the yellow.. I could use replace color,
What I'm basically trying to do is be able to change stuff in images/screenshots, like add a pattern to a white shirt (so, get rid of all of the white), but completely preserve the darkness of its wrinkles/shadows etc. A friend told me I should just desaturate it, then make it like 50% transparent, then duplicate it so there's 2 of those layers.. and add the new pattern behind it. But it doesn't look that good..

I have just updated to Autocad 2013. While working on existing drawings (previously created in V2012), I am having issues with the SCALE command. Most times, but not always, when I add a line or block, with a base point on an existing line or object and try to scale it, I get an "extremely small scale factor ignored" message, although I did not get a chance to enter a scale factor. While it appears most times, but not always, if I draw a new line in empty space on that same drawing, I am able to use the SCALE command without problems. I also have the same issue when trying to scale an existing line or block, most times but not always.
Here is a copy of the command line while I am trying to make it work:
Command: l
LINE
Specify first point:
Specify next point or [Undo]: 100
Specify next point or [Undo]:
Command: sc
SCALE
Select objects: 1 found
Select objects:
Specify base point:
Specify scale factor or [Copy/Reference]:
Extremely small scale factor ignored.
Command:
SCALE
Select objects: Specify opposite corner: 1 found
Select objects: Specify opposite corner: 1 found, 2 total
Select objects:
Specify base point:
Specify scale factor or [Copy/Reference]:
Extremely small scale factor ignored.
If you notice, it does not give me the chance to enter a scale factor. As soon as I pick the base point, it skips over to the error message, yet displays the scale factor prompt with a blank factor. I'm experiencing this issue on various files (not all but most), so I don't think it is a corrupt file. Why I get this and if I can correct it?

I have a floor plan with a very long footprint in a "View" drawn at a convenient scale.
The long building had to be broken to be put on several different "Sheets", and each of the floor plans on each of the sheet has a scale.
When I change the scale of the partial plan on one "Sheet", all the other sheets also change to the same scale and also the original view changes to the new scale.
Is there a way to assign the desired scale of the plan on one sheet without affecting the scale on the other sheets and on the original drawing view?

am in the process of setting up a standard file for all designers to use our local office. This file will have most of the styles created for profiles, alignments, surfaces, profile views, etc... as mostly specified by the customer and industry standards.
I am having trouble maintaining the correct annotation scale in the viewport in paperspace and when plotting.
The attached word document has 3 figures. Fig 1 shows the correct viewport scale and correct annotation scale. Fig 2 shows how the annotation scale abruptly changes during the plotting process. This abrupt annotation scale change sometimes happens during the regen process or when I switch from layout to model space and back to layout.The annotation scale goes from 1:1 to 1:40 just as in the viewport. This change in annotation scale is not supposed to happen because I want to preserve a certain plotting height for my text versus a viewport scale by using various annotation scales.
I have researched the procedures for annotation scale and have not found any info related to this "abrupt change in annotation scale".
Curiously , this abrupt change in annotation scale does not happen if the text does not belong to any styles within Civil 3D. Stand alone text stays at the correct annotation scale and is not affected in the same way.

We have recently noticed that after printing a PDF of a drawing I plotted from AutoCAD we are coming up with differences when we double check the scale on the printed hardcopy using a carpenter ruler.
For example, there is a dimension labeled on the drawing of 200 ft. However, if I try to scale this out with a carpenter's ruler at the drawing was set to (say for instance it is 1 inch = 100 ft) I am coming up short of the 2 inches it should be (typically come up around an 1-15/16" or around 194 feet, approx 97% of the correct amount).
In the Page Setup Manager in AutoCAD, I have the following options selected (see the print screen as well):
Printer/plotter selected: DWG to PDF.pc3
Paper Size: ANSI full bleed B (11.00 x 17.00 Inches)
What to Plot: Layout
I don't have a plot scale scale other than the default 1" = 1'
No plot style selected
Then, on the print menu when I open the PDF that I have exported from AutoCAD, I have the following settings (see the print screens I have attached):
Printer: The printer I use (Konica Minolta c650 Series PCL)
And I have selected the Options "Auto Rotate and Center" and "Choose paper source by PDF page size**"
** Note, that I have tried unselecting the "Choose paper source by PDF page size" option and accordingly changed the paper size in the "Page Setup..." button at the btoom to match the document size (i.e. 11.0 x 17.0in) and it gets the difference to be closer (i.e. I now get 198 ft but some of my border gets cut off). See the print screen below for this a print screen of the print menu and sub-menu of Page Setup showing the paper size selected.
I saw that some people in other forums state that there is no real solution when trying to scale off of PDF's and that there should be a disclaimer saying as much if you are to send the file out to a customer who may rely on doing some in the field scaling from the printed copy of the PDF file. I find it hard to believe there is no solution as we have received some drawings from others whom the scaling works just fine.

When I open a new drawing in my AutoCAD 2013 that I just recently installed last week, I encounter a problem that I am not familiar with from previus versions of AutoCAD I have worked on. First of all, the units default to decimal, and I want them to default to architectural, with feet and inches. I have to type UNITS in the command line every time I open a new drawing in order to adjust this. I have AutoCAD for Architecture 2012 on another computer, and the program automatically defaults to architectural units upon opening up. Just to let you know, the program I am having this difficulty with is part of a package called Autodesk Building Design Suite 2013. I was under the impression that it included AutoCAd for Architecture, but I think it has only standard AutoCAD.
The scale of the objects I draw vs. the scale of the drawing field is very out of proportion. What I mean is, when I open a new drawing and draw a 30' -0" line, the line appears so long on the screen that I cannot see the whole object, even if I zoom out to the maximum. I should be able to see the object in it's entirety. In fact, when I draw a line that is only 12" long, even when the zoom is all the way out, the line looks huge in length. I have tried adjusting the units to the architectural/inches setting of course, and I have tried adjusting the scale in model space from 1:1 to 1/4'=1'-0", but nothing is working.

I am working on automating page setups in model space and am looking for a way to set the plot scale equal to the annotation scale for scaled drawings with
(setvar "filedia" 0)
(setq a (getstring (getvar "cannoscale")))
(command "-plot" "YES" "MODEL" "" "" "" "" "" "" !A "" "" "" "" "" "" "_Y" "_N")
Setting the plot scale with !A causes the lisp to fail. However, when running each prompt through the command line individually, !A works fine. what is missing?

When I'm editing pix, and need a quick large solid brush for a couple seconds, (1-inch dia), I slide "scale", but it's nearly impossible to manually rest scale back to default without restarting Gimp...
Can there be a dot-button beside scale that auto-sets scale back to default..? and/or a timer on scale changes that resets scale back to default after ten-seconds..?

I am trying to insert a block into a file in Acad 2014 and it comes in too large. If I insert the same block into the same file using Acad 2012 it comes in at the correct scale. Doesn't seem to matter if insunits is 0 or 1, or insunitsdefsource or insunitsdeftarget are also 0 or 1.
There must be some variable or variables I'm missing.

I have a Viewport set to scale 1:100 and the Viewport is locked.The Annotation Scale displayed in the Viewport was 1:50.
When I clicked on the Synchronize Icon beside the Viewport Scale, the Viewport Scale changed, even though the Viewport was locked.
I was expecting the Annotation Scale to synchronize to the Viewport Scale.
Is this how it is supposed to work? and why does a locked Viewport Scale change?

I have a block that i would like to scale based on the plot scale when plotting.
We set up our drawings full size and occasionally we want to plot them at half size. We do this by setting the plot scale to 1:2 (custom) in the plotting dialog. We have a few blocks that we want to print at the same size on paper, essentially become twice as big.
Is there is a way to fix the size or just set a few scale states and have them automatically adjust based on the plot scale (not drawing/annotative scale)?

I have a drawing with several layouts, and in one particular layout only, I want the text to be smaller than the annotation scale would dictate (the viewport is 1"=300', but I want the text to display at 1"=50' annotation scale).
I tried selecting the viewport and changing the "annotation scale" property to 1"=50', then the "standard scale" property to 1"=300'.
Strangely, this seems to work for a bunch of MText objects I have in the drawing, but it won't work for an alignment station label group or for a particular linetype...for some reason, those two things insist on having their annotation scale equal to the viewport scale.
I tried messing around with the alignment station label group's style but couldn't figure anything out. As far as the line/linetype, I'm completely at a loss why that one wouldn't change.
