Lightroom Export NIGHTMARE!!

As long as i can remember i have been exporting my images from Lightroom using the colour space 'AbobeRGB'.
I've often thought colour rendition was muted but never investigated until tonight.

Not sure if that colourspace is default or whether i tweaked it, either way i changed it to 'sRGB' and my exported pictures are 100% better!

Let me know your thoughts?

It seems my copy of LR4 is set to export as sRGB. I did try using AdobeRGB, just the other day, but that was trying to resolve a B&W printing problem. The monitor images looked the same which ever. My club always wants DPI's in sRGB and I think this forum does as well

sRGB is generally default - make sure camera and PS or LR are set to the same.

Unless you want to get involved in more serious profiling then sRGB will serve very well. I have always stuck with that - AdobeRGB can indeed lead to more muted tones.

Depends what I'm exporting for.

For general web use and printing at home I use sRGB. If exporting for prints from DSCL I use their own profile. If exporting for inter club PDI competitions then its AdobeRGB

Alan, are you sure the interclub competitions are projecting using the AdobeRGB colour space?

I ask because we are using sRGB and so are the other clubs I know.

Sadly, many people entering even our club competitions find it difficult to follow the instructions so we use sRGB as a default. I also ask for that colour space when producing the annual ADAPS Year Book, but I get a real assortment....

Yep John. From the rule book:
"All images MUST be prepared in JPEG format with a maximum file size of 450Kb and a maximum pixel dimension of 1024 (horizontal) x 768 (vertical). The files will be projected using equipment calibrated using AdobeRGB1998 Colour settings and Colour Temperature of 6500K."

Thanks, very interesting. It has consequences for inter-federation competitions.

Thats in our rule book.

Just been on the Northern Counties Photographic Federation (NCPF) website. Checked rules out for their competitions and it says:
"b) Projected Digital Image files must be prepared in JPEG format with a maximum file size of
900KB and with maximum pixel dimensions of 1024 and 768 in the horizontal and vertical planes
respectively.
c) The image titles must be the same as on the entry form and must be in the format : AC3#Club
ID Code#Image Number# Author’s Initials as described and shown in the examples on the entry
form. The images will be projected for judging using a projector with a standard output size of
1024 pix 768 pix Colour Setting of sRBG [or Adobe RBG]and Colour Temperature of 6500K.
There will not be any correction of original images prior to projection."

Extract from the PAGB competition rules link

File Format, Size and Projection
5.1 Files must be jpeg format, RGB mode (for both colour and monochrome PDIs) in sRGB colour space.

All a little off topic. My advise to the OP would be to use sRGB until you have a specific reason not to

EDIT:Sorry Barrie, that wasn't directed at you. I was typing before I saw your post

It,s a little odd because the size now used is 1400 x 1050 pixels.

Not going to answer the poll as I use ProPhotoRGB and sRGB, AND occasionally Adobe - depending what the Export is being used for.
Eg, if to post here in the gallery, then sRGB.

I believe it's the new standard for projectors. At least that's used our latest club projector.

It's the current DPI standard for L&CPU competitions. We moved to it as a club so we could conveniently use any images contributed in all competitions.

If anyone ahould ever want a 1024x768 version, then it's a simple crop with no change in proportions.

As Barrie says the requirement at Durham Photographic Society is for sRGB images of 1400 x 1050 pixels. John says its the same for ADAPS which is in line with the requirements of the Photographic Alliance of Great Britain and Royal Photographic Society and the Lancashire and Cheshire Photographic Union.

I'm suprised Blythman quotes the old 1024 x 768 requirement from the Northern Counties Photographic Federation rule book.
Alan, is this the latest NCPF rule book? We at Durham enter their competitions and exhibitions using the larger file size in sRGB.
