Finally! We are now ready to take this wonderful work of ART and put it out on social media for all to see and envy! What should we do? What settings? sRGB? ProPhoto? Adobe???? ARGH!
This is simple! Since the vast majority of displays out today are sRGB capable, your best bet and recommended choice would be JPEG and sRGB. sRGB will assure you that it looks very much the same over a large amount of different displays. Personally, when I have tested this exporting bright, vibrant and saturated colors, there tends to be a little fall off from the displayed image in Lightroom. It is very slight and remember, you’re going from a HUGE color space to a much smaller one. I have also exported as ProPhoto and, to me, it looks exactly as it did in Lightroom. I use an iMac 5k, and an iPhone 7 – maybe they display the colors nicely!! To be honest, it looks better to me exported as ProPhoto and that is against what most say you should be doing (exporting to sRGB is the norm).
If you chose to send the file to Photoshop(photoshop online) as sRGB instead of ProPhoto (Earlier in this process), you would have had this drop off in color information earlier in the editing process. I bring this up because you’re going to lose a little bit (AND IT IS VERY SMALL) anyway so you may as well keep that information right up until the end when it is time to export.
