Thanks for the comments Bob! 
It's an insane amount of bluebells isn't it!?! It's the only wood around here that has so many...
When i convert the RAW image in Photoshop, i'm assuming the EXIF data should still be in the file? I was playing with 2 files at one point, i had this version and the same shot stopped down a couple of points. I was playing with a layer mask, but didn't like the results so deleted it and kept the original. The only other thing i did was copy the original layer, up the contrast slightly, then merge down. Would any of this cause the loss of EXIF data? Or would saving for web lose it!?!
Thanks for the link, i'll give that a go.
