I think the demonstration at around 6:30 in the video is likely to misinform people. The assigned profile of the image is changed from sRGB to Adobe RGB, and brighter colors appear once is it assigned Adobe RGB. This demonstrates what happens when an image created in the Adobe RGB color space is improperly tagged sRGB. It doesn't mean that you could not create an image in the sRGB color space with those brighter colors.
Yup. Changing a color profile of a picture that was stored by a camera with a certain color profile does not make any sense without converting RGB values of every pixel.
Thanks for the informative video. You described this confusing subject in a clear and straightforward way. The crayons and pastels example was very helpful.
One more thing, you need a monitor that is able to show adobeRGB color space, otherwise you would be editing adobeRGB photos blindly when you're using an sRGB monitor, since it is unable to show the expanded color gamut in the AdobeRGB space. That is why now I'm investing in a more professional monitor that shows AdobeRGB.
Assigning a profile 'clips' the gamut you are moving into, that is why the lady's hat shifted colour. There was no adaptation to preserve the appearance. I think you should make that clear after 9 mins as you seem to suggest that people might actually improve the image by assigning. Of course that CAN happen but only if the image has no profile or an incorrect profile. If you 'assign' a larger profile, you get a more saturated image with colour shifts. Such as assigning AdobeRGB to an sRGB image. Sometimes the image looks better by accident, you have broken it! Only assign when no embedded profile, if you guess the correct one, bingo! If you guess wrong, you are breaking your image.
Agree with most commenters, this video is full of false and misleading information. ProPhoto as working color space makes sense because current wide gamut monitors and fine art printers support gamuts larger than Adobe RGB. The issue with gradients can be avoided by using a color depth of 16 bit, which admittedly comes with the drawback of larger files. Not sure how what he does with assigning profiles makes any sense apart from falsefying colors, instead conversion should be used. And yeah, for most quality-conscious shooters the camera setting of the color space does not matter, because it does not apply to RAW images.
I'm confused. On another site I was informed that the number of colors in the sRGB versus the AdobeRGB color spaces is about the same; however the available saturation of those colors is much greater in AdobeRGB. Can you clear this up for me?
The editing with photoshop of an Adobe RGB photo or sRGB photo produce better JPEG photo for web? The Adobe RGB and sRGB are irrelevant with raw photos?
Well, It depends of the paper you are gonna use: of the gamut's size of it. If you use matte paper, Adobe RGB will not be good enough cause of the paper gamut's size, but if you use exhibition fiber paper it will be perfect.
This is totally uninformed. It totally depends on the print. MANY print media exceeds and even far exceeds SRGB! Lumachrome HD out of Nevada Art Printers (super gloss acrylic mounts) is even WIDER than Adobe RGB! Best to work in Beta RGB for it.
would you let me know how to get photo prints exactly(close to) that we see in the monitor. The prints are coming darker than that is shown in monitor, most probably because of the monitor brightness. I have gone through some information about calibrating monitor and printer with colormunki device... is there any other way to do this job done...
you should calibrate it, but this is a good check for the luminance / brightness of your screen: www.drycreekphoto.com/Learn/Calibration/monitor_sensitivity.html
If I shoot RAW (which is 99% of the time) does camera setting of AdobeRGB vs ProPhoto really matter? This info isn't baked in is it? Just wondering if it has some effect on how it imports and converts to DNG in LR (cc). Do I need to assign the profile in an import preset?
I think the images are just "tagged" with the label of the color space. If you chose, in camera, to shoot in AdobeRGB the photo it will be just tagged with that and still has the sRGB space embedded in it for future use by a photographer. But the problem is that you need a monitor that is capable to show AdobeRGB color space in the first place. All of our monitors are sRGB. I hope that helped.
7:54 then why don't you use the "adobe wide gamut rgb" (16 bit per channel) so you don't have this effect combining with "adobe rgb" and "sRGB" (8 bit per channel)
jihong choi Assigning simply changes the interpretation of the stored values. Converting additionally changes the values in order to maintain the same color.
Looks like Ben Long has no clue about the topic (and I thought he was some kind of expert before seeing this video!). If you shoot RAW then the color setting on your camera doesn't matter. Lightroom users for example are working Prophoto like colorspace because that colorspace can contain all the colors the camera captures in RAW and this cannot be changed. Using the "assign profile" command to go from one colorspace to another is just terrible wrong, the colors look whacky when assigned to the wrong colorspace and the should (because they are now mapped incorrectly!) The "convert to profile" is used to convert from one colorspace to another. (the "assign profile" is used when the profile information is missing from the metadata and it has to be the right one or the image looks wrong)
Jón Tryggvason , my take is his use of tagging is merely to show how the same device numbers yield different color and saturation values in different colorspaces. This is not a lesson on proper workflow.
Agree, my old Canon EOS 20D can natively capture many colours outside of Adobe RGB so when importing the .raw image I use the Pro Photo space. Make all edits in Pro Phot then convert to RGB or sRGB as required leaving the .psd master file as Pro Photo. Using this method i have never seen any of the problems he mentions in this video.
Actually it looks like YOU might not have a clue. Cameras can capture MORE colors than Prophoto RGB! And even if that was true not everyone chooses to work in Prophoto RGB.
