1. Re: Can Adobe be fixed to support color profile png's?
Chris Cox Apr 2, 2013 8:59 PM (in response to Astara_)png-color-profile-test.png opens just fine in Photoshop CS6, CS5, CS4, and CS3.
And they save it with the profile and reopen it correctly as well.
The profile might be stripped if you use a third party PNG plugin, or if you have your color settings set to ignore profiles.

You need to hover over them in firefox ... well maybe you don't have
image profiles turned on... or such... um.....
(if you use firefox)
in about:config you need to have color management turned on:
gfx.color_management.mode integer 2
gfx.color_management.rendering_intent integer 0
+ ideally correct profile for your monitor in
gfx.color_management.display_profile string=C:\windows\system32\spool\drivers\color\<your profile.icm>
Supposedly Chrome also works.

Chris Cox Apr 2, 2013 11:31 PM (in response to Noel Carboni)Save For Web saves the profile if you tell it to save the profile (default to no profile, no metadata).
And Save As... PNG saves the profile unless you disable it in the save dialog.

6. Re: Can Adobe be fixed to support color profile png's?
Astara_ Apr 2, 2013 11:52 PM (in response to Noel Carboni)I was doing file save as......
Unfortunately, this does not show the image washing out / lack of depth problem I was trying to show last time. This was purely a plugin problem that stripped the profile. Once that was disabled, I got the message "Embedded Profile Mismatch" that pop's up when there's any profile on the pic other than my monitor's...
I also verified that using the embedded profile and saving works correctly.
That being said, I still find I need to convert png's from my monitor profile to sRGB for them to look even close to as as accurate in Windows or FF as they do in CS5.
Jpgs and tiffs don't have this problem, so I'm still at a loss, as going through an extra step of converting to a poopy profile just to get it to look the same as jpg's and tiffs with good profiles is a pain.
So I just just go need to get the toenail clippings out of my mouth now that I'm getting my foot out of my mouth....*ahem*...
*sigh*...

No, Save For Web does not save the profile in PNG, and when you choose PNG in the SFW dialog, the Embed Color Profile checkbox vanishes from the dialog.
The OP will be working with a wider gamut than sRGB in Photoshop then using SFW to export to PNG and therefore with no profile. The browsers/viewers will assume the profile-lacking images are sRGB and therefore they will look washed-out in comparison to how they looked in Photoshop.

I save them in the same way I save jpg's and tiff's -- it asks me on those if I want to save a profile with them or not. I would assume that with png there is no choice it embeds my working monitor profile automatically.
If that's not the case, then that's an obvious bug.

10. Re: Can Adobe be fixed to support color profile png's?
Chris Cox Apr 3, 2013 10:12 AM (in response to Astara_)No, Photoshop embeds the document profile.
The only time it could embed a monitor profile is if you set your RGB workingspace to your monitor profile and disabled loading of existing profiles in documents. (because embedding the monitor profile is usually a mistake)

11. Re: Can Adobe be fixed to support color profile png's?
conroy Apr 3, 2013 10:45 AM (in response to Chris Cox)I use CS6 and its SFW definitely does not embed a profile in PNG.
You said in August 2012 that SFW does not embed the profile in PNG:
This is my SFW plug-in version according to Help > System Info:
Save for Web 13.0, Copyright © 1999-2012 Adobe Systems Incorporated - from the file “Save for Web.plugin”
Here is my SFW dialog with no Embed Color Profile checkbox when PNG-24 is the format:

Astara_ Apr 3, 2013 11:56 AM (in response to Chris Cox)CS5. I reported the problem in CS5, AFAIK it hasn't been fixed. I see nothing like the dialog you have -- it only asks 'interlaced or not' (FSA) -- just tried to save my cur doc to web, it says:
The image exceeds the size Save for Web & Devices was designed for. You may experience out of memory errors and slow performance. Are you sure you want to continue.
So, I don't think it's been fixed and AFAIK I have the latest update for CS5.

13. Re: Can Adobe be fixed to support color profile png's?
Astara_ Apr 3, 2013 12:14 PM (in response to Astara_)How did the SFW thing even come up?? When I embed profiles in jpg and tiff, I do it as part of the File Save or File Save As dialog. I can choose what profile to save it with -- and I usually save it with my currently calibrated monitor profile -- as that color profile is what was used to create the picture. Why would I want to convert them to some other profile?? Only thing I have needed to convert have been PNG's because it doesn't embed my monitor profile in the PNG the same way jpg and tiff do.
If it did, png's would look the same as jpgs and tiffs... but the jpgs and tiffs have the full depth of color and look the same as they do in PS. png's look washed out because -- it's been my belief that PS is not storing my profile in the png, but setting a bit in the file to use the sRGB profile.
AFAIK, PNG provided for a sRGB profile-compat bit -- so images that were compat w/that profile could just set a bit rather than including a profile. I see no evidence that PS is saving my monitor profile with the PNG.
My 'settings' for RGB are to convert to working RGB profile which is my monitor profile.
I do have it set to ask me abou profile mismatches on opening or pasting.
Since I don't get a 'this document has a different color profile than the working space'
message when I edit most png's, I assume it has none. Thus from my settings
it should autoconvert it to my monitor profile and save that on save -- which seems to be what happens when I save as jpg or tiff (or I can check off the box to save profile...but I usually don't).

SFW came up because its lack of profile embedding when exporting PNG (until a very recent version which you do not have) was one explanation for your problem of exported PNGs looking different to the original documents in Photoshop. Since we now know that you don't use SFW, nobody need mention it again in this thread.

NO, it hasn't, not for perpetual license holders on Windows, who still only have the option of updating to 13.0.1.
Apparently that bit of functionality was added to Photoshop CS6 in 13.1, as I do see it in 13.1.2.

Can't say I blame you.
It would be nice if Adobe would ultimately release all the bugfixes to PC users with perpetual licenses.

But bugfixes for broken functionality .. um... only slightly less shady than witholding security bugfixes...
