Hi all.

I've been having fun adding split tones effect to a lot of my monos recently, sepia shoadows and blue highlights. I've found its a really nice subtle effect when used lightly.

Unfortunately, I've found the yellow tint seems to get lost completely in eporting from lightroom as a jpeg, what looks good as a raw looks much bluer as a jpeg, and to retain the effect I've got to boost the effect in raw to unbearable levels.

Any hints on more accurate colous for web viewing across file types?

Check how you are exporting. LR by default uses Pro RGB as a colourspace, make sure you're exporting in sRGB . This may be the problem.

Secondly are you using a calibrated and profiled monitor. If not this can also cause problems.

finally Mac or PC ?
 
I have been having this problem aswell, images after exporting from lightroom look really really flat and dead. I'll try your tip, ifnot i will upload onto the web as a TIFF.

sRGB is a W3C endorsed colour space. Basically an attempt to standardise digital image colour profiles for internet use etc.


Export from lightroom as sRGB, then work in an sRGB profile in photoshop etc. Finally exporting again as sRGB. You should see a pretty much exact replica of that in your jpeg afterwards. Remember though that browsers will always make jpeg images slightly dull/lifeless.
 
Hello All!

I shoot film and have only just purchased my first digi so not sure my contribution here is 'worthy' or not but my understanding is that jpeg (8-bit) can only handle about 256 diff colours whereas RAW (16-bit) handles about 65000(?) colours. Also, everytime you save a jpeg you lose some info. So why not work with the RAW file?

Please forgive my ignorance. Can someone explain to me? :shrug:
 
true
you work with raw
but have to upload jpeg (or bmp or tiff) so browsers can see it!
 
Full size RAWs from the camera are 8Mb+ so unwieldy, jepgs are kinda the standard web-dustribution format.

I'm aware of the 8/16bit difference, but I diudn't know that could take a picture with a subtle sepia cast and make it blue
:thinking:
