| | Posted: | | | | I hope this topic doesnt get ugly, but I want to hear opinions.
There are a few color spaces out there to use such as CMYK, sRGB, Adobe RGB, Pantone (Skip's favorite I am guessing), and many others. Each has advantages and disadvantages. There will also always be debate over if a picture is over saturated, under saturated, not sharp enough. But do you think that submissions should be restricted at a certain color space(s)? | | | Schultzy - http://www.michaelschultz.net

| | Posted: | | | | It's not going to make that much difference unless our systems are calibrated to that colour space, so I'm not sure I would support a move to make it a requirement.
If it was a requirement though, I would vote for sRGB. It's the Windows default and the default for the Web. Not sure why someone would vote for any other standard given the context to be honest, so will read the ensuing discussion with interest. | | | | Last edited: by Squirrelecto |

Adobe RGB is used by a lot of photographers (unless you are my GF who hates it). CMYK I belive is more for printing things like posters. Pantone is a new for me and first came across it when Skip submitted cover images. But from my understanding is only used by Pantone products because it is not open source. This may be a reason in the old forums some mentioned Skip's images not look right to them. | | | Schultzy - http://www.michaelschultz.net

| | Posted: | | | | 95% of people are using Windows, so this is really a moot point.
That isn't going to make it any easier, though, because people all see the pictures differently. No two pair of eyeballs is the same, just like every monitor is different, etc.

I honestly don't understand the question, so I voted Don't Care. I wonder if most people would say that same.  CMYK and RBG are color palettes. When you're in Photoshop, you can select to switch between the two. Pantone is proprietary and historically a colors system for printing. CMYK is for printing too. It tries to simulate on screen what you'll see when the image is printed. RGB is what you'll find most JPEGs coded as. I just checked a few of the images that come from the database that Skip uploaded with his "Pantone color standard" clause and they all check out as RGB in Photoshop. I don't know if Skip converts them to RGB before he contributes (a question for Skip) or whether Invelos stores all images as RGB regardless (a question for Invelos). I'm sure Vibrocount or others can fill in the details better than I have.  schultzy, have you seen any images come from the main database in anything other than RGB? Or have you contributed anything in a format other than RGB? | | | ...James

schultzy, have you seen any images come from the main database in anything other than RGB? Or have you contributed anything in a format other than RGB? I had been using Adobe RGB, but went to sRGB after I rebuilt my PC. I have submitted as both. I was just curious as to what others thought. Not to pick on Skip or anything, but he notes in his image contributions he uses pantone and to me a number of his submissions look saturated in red when viewed on different PCs. I know that what you see depends on video card, monitor, calibration, and your eyes. But just wondering what others use (which I am sure is RGB or sRGB), if people thought maybe we should just use one or two, or people cared at all. | | | Schultzy - http://www.michaelschultz.net

Maybe we should start a poll on this? Your technique would only be valid if you had calibrated your monitor to match your actual DVD case with whatever color space you use beforehand. | | | | My Home Theater |

| | Posted: | | | | Technically JPEG is treated as sRGB though many [professional] image handling programs can tag it with other colour spaces. Most monitors, calibrated or not, have a gamut [the actual colours reproduced] that is very close to sRGB; some newer ones are close to AdobeRGB, which is wider in most areas but lacks in compared to sRGB in one. A sawer's handful of pro monitors cover wide gamut spaces.
That all does not matter when the images are viewed in a non-colour-managed environment, which includes all Web browsers save Safari, or low level image viewers like IrfanView. While most images with AdobeRGB defined will not change their colours drastically in these cases - the colours are close enough to sRGB - pictures with a wide gamut attached/tagged will suffer greatly.
Conclusion: With JPEG - which is used in DVDP - sRGB is the most sensible colour space for submission. Only if you know what you are doing and you go in to do major [colour] edits after scanning should you use TIFF, 16 bit and a wide gamut space from AdobeRGB upwards. |

| | Posted: | | | | I think if you start requiring a specific 'colour space' quite a lot of people, even those who contribute regularly (like myself) will not bother as we have no idea what you're talking about. hal9g says: Quote:

That isn't the point... the point is you could have two different people view the image on your monitor and they could easily disagree over which was (subjectively) better. Similarly you could view your images on one monitor and descide image A is better but if you then were looking on someone else's PC image A could look worse... fine for you (if you are going to use one moitor for the rest of your life) but what if your monitor is differently set up to the vast majority out there and you are Voting Yes for an image that may look worse on most people's systems. | | | | It is dangerous to be right in matters where established men are wrong |

That's not true.
If I am comparing both images to the original cover on the same monitor, what difference does it make how the monitor is calibrated. Both images will be "off" in the same way if it is not properly calibrated, so which ever one matches more closely is still gonna be the better choice!
I pull up the contribution which shows the old image side by side with the new image on the same screen.
Then I pull out the DVD in question, and hold the cover art up next to each of the two images on the screen. I use the same set of eyeballs to perform this compartive function for each image on the screen.
