Color problem when uploading

[adz]

Good day,
Decided to try in this section of the MB, where it belongs. Hopefully to get my problem solved. Copied from this topic

It seems that when importing JPEGs into Adobe Dreamweaver to put them on my site, the colours tend to get a bit toned down, compared to how they look in Photoshop. And thus on my site and here as well. I don't seem to be able to fix this, any ideas?
(to get an idea how the colours change, put one of your own pictures from your harddisk as a background on your desktop in Windows Vista. Compare this to the same one opened in Photoshop. The difference between the two (at least at my computer) is about the same. I hope my problem is clear?)

Following responses there:

Hi Adz,
About the color problem
I think you are shooting in Adobe RGB camera settings (large color dept)
if you save as in jpeg you will lose some color dept because jpg is sRGB (Microsoft web based)
Maybe this link(in Dutch) helps

and my own:

I actually shot in sRGB (just found out, never paid much attention to it, I need more time to fiddle with the camera), but does this matter if you shoot in RAW?
And if I open the .jpg file in Photoshop, the colours look like I want them to look. So no problem there, it seems. But as soon as I import it in Dreamweaver, the colours seem to change. Still not able to find anything about it in Dreamweaver help as well.
So still some questionmarks above my head.
But thanks for the help so far,
Ard

Anyone?

TIA,
Ard

Hi Ard,

Please open the desired image in Photoshop and do "Edit - Convert to Profile". Don't click OK, but check the profile name in the 'Source Space" box.

All I want to know is which profile is used according to that box.

Cheers,
Iwan

Must be a conversion problem between AdobeRGB and sRGB,for internet you need to use sRGB.

Wow, that´s quick.
It says Adobe RGB (1998)
I think we have the reason nailed here?

Decided to try out the Convert to profile function and put it in sRGB, with the following result:
With AdobeRGB:

With sRGB:

Makes a huge difference indeed. Please tell me if I need to convert it to another (even better) profile for publishing on the internet.

Thanks a million!

No, the standard for internet is sRGB. Although when you want to print out your pictures it is better to use Adobe RGB.

And that depends on if you are printing them at home or in a photo store. In a photostore they also use sRGB as main printer setting

Voila !

Most likely it's this color profile that's causing you trouble.

All images via Internet are displayed in sRGB, even if you upload them in a different color profile. Most likely Dreamwaver is doing the same thing.

Nevertheless Adobe 1998 is the widest colorspace with the best performance, and it's best to keep working with that. When you prepare your images for publication, all you need to do in Photoshop is "Edit - Convert to Profile" and set the profile to sRGB.

If you create an "Action" to do this, you can just press a desired F-button to do the trick in milliseconds. For me it's just pressing F4, and the image is converted to sRGB without any loss of color.

You see, these Aviation Photoshop Courses are good for something.....

This has been a great help, I´d been searching the help-topics in Photoshop, but was unable to find it. You gotta love this Message board.

Thanks!!!

And just a quick follow-up/in-between question:

Does it matter what setting you have in your camera when shooting RAW?

TIA,
Ard

[Iwan Bogels]

Nope !

RAW has no assigned working space. You will do that yourself when you convert your RAW-image to any other image format (JPG, PSD, TIF, GIF) on your PC.

And the same goes for camera settings about internal sharpening, white balance and contrast. These settings don't apply to RAW, but only to JPG's which are created inside the camera.

Photoshop cursussen, you've gotta love them !

You can change it when you open the picture in Photoshop CameraRAW under the opened picture there is a box where you can convert from Photopro (even bigger as the colourrange of AdobeRGB)till sRGB and you are able to change the bitdepth too overhere.

i played last week with this(camera settings on a canon 350d), and my findings is: it does make a difference! when i change the settings to set 1(all on +2) ,set 2 (all on +1) set 3 (all on 0) and the parameter 1 and 2(pre set)

after shooting i load them to my pc, convert raw to tiff 8bit(with digital photo professional)

how can you explain this?

i also see a difference on the display on the camera, and that is still a raw picture. if this does not make a difference why you can choose this when you are shooting i raw?

[Iwan Bogels]

Hi Jos,

The camera is showing the embedded JPG, so that explains the difference. There should be no differences in RAW, so I don't understand why you are seeing things differently. The fact that you can change setting while shooting RAW is simple. You are adjusting settings for JPG, which you are not using.

Iwan

Iwan, pal

They better be! With all the promotion you are giving them, I expect nothing but top-notch Photoshoppers to emerge from those courses. So, if the simple basics of colour profiling would not be part of the course, I don't know what would be!

OT: A final tip here may be, not to confuse 'Convert to Profile' with 'Assign Profile'. The former tries to preserve appearance (based on settings you can chose), the latter will often change it (when there is a difference between how the file was made and what you assign to it).
This preservation during conversion has limited abilities though, due to the constraints of colour spaces as explained by Iwan. For instance, CMYK (often used for printed matters) cannot show all that RGB can, so colours like flashy red or deep blue are bound to change.
