Personally, I do no think the Color RGB Color Space should have any influence if working in Gray Scale. There may be a reason why it does, and maybe someone with more experience may chime up with the answer

At least you are getting the same as me and its not me thats going crazy. The only work around is to always have the Working RGB set to Adobe RGB 1998 and then everything aligns properly but this to me defeats the object especially when importing color files which really need to be in ProPhoto to ensure you are dealing with all possible colors. Wonder if its a bug or done intentionally.

Follow Up Setting the default RGB Working Color Space to either sRGB or Abobe RGB makes the K value correct (50%) Setting the default RGB Working Color Space to ProPhoto RGB makes the K value (43%) Why does the choice of the RGB Color Space affect the K value if you open a New Document in Gray Gamma 2.2

What I cannot understand is this... I create a New document in grayscale using my Working Gray: Gray Gamma 2.2 I then fill that document with RGB 128,128,128 and this is the result I do the same only this time, I select RGB and Use Adobe RGB 1998 I then fill that document with RGB 128,128,128 and this is the result Isn't Adobe RGB 1998 and Gray Gamma 2.2 supposed to have the same Gamma Value of 2.2 ? Should they not display the same values ? I appreciate that if I had chosen ProPhoto RGB instead of Adobe RGB the values should be different because ProPhoto has a Gamma value of 1.8 Workflow When I am scanning black and white Negatives, I am outputting them from the scanner in a Gray Gamma 2.2 profile and then bringing them into Photoshop which is set to Gray Gamma 2.2 in the Color Settings. What worrying me is that, what I thought should be 50% gray is actually been reported by Photoshop at 43%

D Fosse wrote Numerical values across color modes relate to your working spaces. If you use gray gamma 2.2, you also need to set RGB values in a color space that actually uses gamma 2.2 - the only one is Adobe RGB. ProPhoto corresponds to gamma 1.8, and sRGB to sGray. The dot gain grays have no RGB equivalent. They're supposed to compensate for ink spreading when it hits paper. There is in fact no particular reason these numbers should match. They're not supposed to. If they do, it's mostly by accident. Please can you explain this further

I created a new Document in Gray Gamma 2.2 I filled the layer with RGB 128,128,128 Placing a target point on the gray layer, the Info Panel Reports RGB 128,128,128 K: 43% HSB: 0,0,50% Plotting the point with a Curve, the Input value reads 145 Can anyone explain why the K: value is not 50% and why the Curve Input in not 128 Ian

I also have had to revert back to the previous version of Photoshop. Can Adobe confirm whether they will fix this or is it time to forget about the Nik Collection.

I saw there was an update to Lightroom 2015.10 so I checked updates but nothing was showing. I decided to Un-Install Lightroom from the Mac and then sign out and back into Creative Cloud and install Lightroom. Lightroom installed but now I have version 2015 which is older than when I un-installed. How can this be ? How can I get CC2015.10 as I am going round in circles

Did you have the latest version of the Creative Cloud app and all notifications turned on in the preferences? It DOES work David, I think you may have mis-read my reply Ian

When ever I made changes to files in my Assets folder, I used to get a notification pop up on my iMac. I have noticed these have for some reason stopped, I no longer receive notifications. Nothing has changed, I have the desktop app enabled to receive notifications. Mac OS X 10.12.3

Lightroom Latest Release Mac OSX 10.12.2 For some time now, I have been having issues with the Tone Curve points not responding with the mouse or the Wacom pen. If I click on either the bottom left or top right point and try to move it with either the mouse or the Wacom pen it doesnt always respond. The mouse has to travel along way before anything happens. The curves in both Photoshop and ACR seem to work fine Anyone else have this issue?

Display Document Profile Thank you, by changing executeAction( idmodalStateChanged, desc46, DialogModes.ALL );in my code did fetch up the dialog window but your code looks cleaner.

I am trying to open the Convert To profile Window, the same as going to Edit > Convert To Profile through a script but I am not having a great deal of success. The Script-Listener outputs the following but I am not able to open the Convert To Profile window from it. var idmodalStateChanged = stringIDToTypeID( "modalStateChanged" ); var desc46 = new ActionDescriptor(); var idLvl = charIDToTypeID( "Lvl " ); desc46.putInteger( idLvl, 1 ); var idStte = charIDToTypeID( "Stte" ); var idStte = charIDToTypeID( "Stte" ); var identer = stringIDToTypeID( "enter" ); desc46.putEnumerated( idStte, idStte, identer ); var idkcanDispatchWhileModal = stringIDToTypeID( "kcanDispatchWhileModal" ); desc46.putBoolean( idkcanDispatchWhileModal, true ); executeAction( idmodalStateChanged, desc46, DialogModes.NO );
