My friend are using Photoshop CC (2014) to produce the photo mix artwork, however, the output in different file format (png, jpg, etc) with default colour setting / profile, the color outcome seemed on different applications and platforms are different, the original color and color depth (with different layers of color depth for sunset scenery) cannot be maintained.

 

Please kindly help to see how to resolve the issue, thank you so much for your help in advance!

I'll leave color management specialists answer in details. What does not make sense is that the jpeg format is ONLY 8-bits and that there is no magical advantage in color for the PNG format: With the correct color profiles embedded, those formats  should show the same output quality of color. The jpeg version could show some posterization effects. What was the color profile of the original file and the other versions? aRGB, Prophoto, ... or sRGB  which supports only a narrower color gamut?

Hello Michel, 

Really thank you so much for your prompt and professional replies and sorry for our late reply here!

As we do not want to have the compression or any quality loss, and so we choose PNG format, we are not quite sure about if this act is correct or not. 

Our color profile orginally is sRGB, which should be the most appropriate one for the web. And as we are creating nft, and we hope the artwork can be viewed on the web, mobile phone or even for printing in good quality, so we choose the resolution of 600 dpi. 

Meanwhile, we are checking that an article mentions the working space and output space can be different, it suggested that we can use Prophoto to get widest color gamut (also as what you said in your reply), and then we need to output it in sRBG space in order to have compatiable with old browsers... we are not sure and still exploring how to do this action in Photoshop.

 

Meanwhile, we had tried to output the artwork in Prophoto profile, but it cannot not be seen (blurred) from the receiver in Whatsapp app, so we wonder if it is the compatibility problem.

 

Thank you so much for your help again!
