Uploaded image different to photoshop

[MikeHoyer]

Was playing with some photos from last year, and liked this one. However when I uploaded it, the colours weren't as bright and saturated as they were in PS... double checked and the PS version is definitely brighter and more colourful. Any idea why...?

wht RGB system are you using as defult in Photoshop?

[James North]

I sometimes find similar things. I never know if it's Photoshop really, I tend to do processing from both my laptop and desktop, and the monitors display are noticably different, what looks right on the laptop comes out all dark on my desktop, and what looks right on the desktop comes out all bright and rough on the laptop.

Are you always working in RGB. If you are changing from CMYK to RGB and visa versa the colours can change sometimes quite dramatically. Also in you are using the 'Save for Web' feature in Photoshop as this can alter the colours slightly. (I don't know why)

The monitor on the Laptop is probably calibrated differently from the Desktop monitor.

Think you may need to calibrate your laptop and desktop moniitors so they are identical. ( or as near as). This will help with colour variations between the two. Contact Calumet in Drummond St NW1 who run periodic courses in this and other related topics. They also run them around the country so may be one in Suffolk. Need to buy the hardware with related software to get them the same. Kit is available mail order from many retailers, but found it easier to deal with face to face with tuition, who can guide you.

Have you tried temporarily switching off colour management in PS when you're editing for the web? The image should then display the same whether viewing in PS or a non-colour managed application (like a Web browser). You can always switch it back on again if you want to later adjust for print.

I would bet your problem is that you are using AdobeRGB in your camera as everyone all over the net says that is what you should be using and Photoshop is reading this in the exif and you are editing in the appropriate colorspace.

However, the internet is solely in sRGB color and if you do not convert the colorspace to sRGB after you finish your editing, you will get much more muted colors when you view them online. If you convert the colorspace you will see what you see in Photoshop after the conversion. Also, make sure you convert and do not assign the colorspace.

What reason do they give for suggesting that people should use AdobeRGB rather than sRGB?

This site explains the differences quite well.

If you only ever want to put your photos on the internet, then I'd say stick with sRGB all the way through your workflow as it will simplify things, however if you want to do anything more with them, then use Adobe RGB (or even ProPhoto if you work with RAW files and have access to a good quality printer). If you do work in Adobe RGB then you should ideally convert images to sRGB as the final step before you save as a jpg.
