I just want to set up photoshop and after effects so I can work with accurate colours that are close to The GS colour space... So does anybody have a profile for photoshop or know of how GS is set up.

cheers Kipper

    Im probably not the right person to answer this but isn't it just the RGB Color Scale. You can go into the color picker and actually set a value of 1-255 for each color and then GameSalad converts it the the proper decimal between 0 and 1 for the engine. Again though. this is just me throwing ideas out there so I could be way wrong or not answering your questions properly.

    Thanks. It is probably me not explaining correctly. In photoshop you can set up profiles for the display so you see your graphics as they are displayed in other programs or printed in other places. I was wondering if someone had made a profile (which can be saved and loaded into photoshop).

    If you open photoshop and have an image open as well as a window displaying a scene live in GS the colour is very different.

    Thanks again Kipper

    I work with the default color profile and do not find any difference in the colors when importing to gs.I have not changed my color setting and they are set to North America General Purpose 2.

    And my proof setup is working cmyk.

    Does this help you.

    On iphone4 the colours are pretty close to the standard profile.

    on a 3gs however, they are VERY different.
    I too would like to know this, as we spend a lot of time tweaking colours on the graphics to get them looking "right" on the 3gs screen.

    Sorry but I can't disagree more. The north American general purpose is a cmyk profile and that is for print. Not screen purposes. I have been working as a designer for ages and have been a colormanagement specialist for a while.
    It all depends on your setup anyway.
    Is your monitor calibrated? Because that is where you start.
    I doubt if iPhones are consistent in displaying colors anyway so I colormanage my apps manually. Or should I say by eye. ;)
    I do not use colormanagement in photoshop because I do not know the GS profile so there is no use for this.
    If anything use at least an Rgb profile.
    And calibrate your Screen if possible.
    If any GS experts know more about GS colour management please do post!

    Was it color or colour in the us ;)

    @Ludwigheijden.I really do not use or touch the default settings for the colors and profiles because the default
    works fine for me and i just told what i saw in my settings because they were going right.I really never to any graphics for printing and so yes rgb is the way to go.But as long as i am satisfied with the setup i dont really care about nor i have gone deeper in this subject of colors managment though i am using photoshop for years now.I really use photoshop to give final touches to my sketches or my 3d renders.
  • LumpAppsLumpApps Posts: 2,867Member
    Yes that's cool, but it isn't good advice in my opinion.

    Then again most of the times not touching the default settings if you don't know what you are doing can be good because it is pretty complicated and I don't want to mess up your workflow.

    No offense 3d10, just advice.

    I think the issue is really knowing how the different screens handle colours.

    Like I say, the retina displays are very close to how I see the images on the mac.
    The non retina displays are much duller, and colours can vary quite drastically.

    @sparkyidr
    You are right.The non retina screen really shows the colors different.But in retina display comes as close to the on screen monitor display.

    Another tip:

    You can always do a reversed calibration.

    Take a graphic on PSD and save as PNG, then have it in a background in a GS project.
    Put it on your iPhone and open it.
    Put your iPhone next to your monitor and calibrate it so that the colors match.
    I would advice to make an proofimage or download one with gradients, contrasts and primary colors. While not really ment for this job you could use something like this:
    http://www.fcenter.ru/img/article/scaners/Canon_CanoScan_8800F/115850.jpg

    (for calibrating you can use the calibrate button in your color tab in your display settings of your mac)

    GS does not have a colourmatching engine (correct me if I'm wrong).
    So it is up to you.
    I'd go for perfect on Retina and not so perfect on non retina.
    Its no surprise Retina shows colors better, that's what you pay for, a better screen.

    Hi Ludwig, I am more worried about comparative colours, and keeping things consistent so wonder if it is possible to do something like a screen shot of my whole desktop with a piece of art in both GS and Photoshop at the same time, then as I know the profile I am running in Photoshop I can then open the grab, add it as a layer to my original image, adjust it so the photoshop side of the grab is the same as the original and then take a profile from the GS area of the grab?

    I am not sure about if this is the right process so if you know how it should be done I would be very grateful.

    I'm almost 99% positive that if you check "Only Web Colors" from the "Color Picker" in PhotoShop, you won't notice even a tiny change on colors on almost any software.

    The other colors however, that cant be achieved by simply changing the RGB integer values (or something like that) can seem different by how they handled. But not the "Web Colors" because it is the most primitive way to get a color.
  • LumpAppsLumpApps Posts: 2,867Member
    @kipper, I don't fully understand what you are explaining but I'll try.
    When you open an image in Photoshop and you have colormanagement is on in photoshop (which is the case because there is no off button photoshop will always change the colors you see on screen (so not the actual document) so it looks the way Photoshop thinks is best.
    So keeping that in mind you will always need a profile which matches your iPhone display (which ever you choose) profile best.
    Why I explain this?
    You mentioned opening a iPhone screen shot in Photoshop and use that as a reference. I don't believe that is possible because of what I explain above.
    So adjusting your colors to that will give a wrong outcome.

    I don't understand what you mean by adjusting the profile from the GS area of the grab.

    Some basics (simplified):
    Colormanagements intention is to give the same colors on a variety of devices, print presses, scanners etc.
    Why? Because all these devices use a different way to display these colours. Some use RGB (additive), others (print) uses CMYK (subtractive) as colors.

    Colormanagement matches colors by using a bunch of numbers in a profile.
    So for example:
    you make an image using screenA
    then you look at this image on screenB
    screenB can show reds from 0-200
    while screenA shows reds from 0-255
    So Reds on screen A are much brighter.
    So what colormanagament does is tell screenA use only reds from 0-200
    This way the reds are the same on both screens.

    Simple huh?

    So when you take a screen shot on screenB (max red is 200) and bring that to ScreenA to change a profile by making the color red 255 again you are going the wrong way. You actualy make Reds on screenA brighter while they should be darker.

    That is why I use the reversed calibration as mentioned above.
    I open a chart on both screens. And have them physically next to each other.
    So screenA shows reds in the chart as 0-255
    ScreenB shows the reds as 0-200
    I now adjust screenA so it matches screen B. So max reds on screenA are 200 as well.
    You can do this with the buttons on your screen but then everything on your mac or other display will be darker, so it is better to make a custom profile in Photoshop (not recommended for novice users) or calibrate your screen with use of your settings: use the calibrate button in your color tab in your display settings of your mac. First make sure you have saved the profile you always use (most of the times this is the standard profile for your display) and after calibrating save your new profile under a new name for example calibrated GS. This way you can switch back to your displays normal profile when you use it for other purposes.

    Tips:
    Mind that this has to be done for every type of iPhone you use. So make a proflie for your Retina and a different one for your other displays.

    Another thing is that you should check your profile on a regular basis.
    Screens tend to be less bright when aging.

    Some screens need to warm up before showing the right colors so turn it on and calibrate an hour or so later.

    @cbt: "Only Web Colors" are web safe colors. Which are safe in all browsers. This has nothing to do with calibration. It is just a color pallet with a variety of colors that are consistent on most platforms.
    Changing the integer values of these colors making them 'unsafe' again.
    I don't thnk these are used very much since most platforms can handle most colors nowadays.

    Many thanks. I think I understand what you are saying... and am very grateful for the information as I am coming at this with a rather odd and twisted logic in my head for the process. So cheers I will try to put into practice what you are saying.

    Its not your head, color-management is on of the most difficult things I have ever encountered. ;)

    Im a concept artists, and have fought with color profiles & monitors on various projects for clients (specially clients with PC's). You have to be careful with profiles, because if everybody doesn't have the same profile, it won't show up the same. You best bet is to always export using the 'Save for web & mobile device', that way it will look the same on everybody's computer. It use to be you would have to over compensate for saturation , before exporting, but seems like newer photoshop versions are better at that.

    But with iOS I don't worry about it its pretty much a non-issue. Apple displays are so close to ipod/iphone, that its not worth worrying about (in my opinion).
