Thanks for your replies so far.
About portrait mode: I personally am a big fan of landscape orientation, still, what I draw from your comments is that I should have (not possible anymore because of the framing I chose with the camera) given the stream of whine more space and importance as one central element of the composition. I'll keep that in mind for my next tries :-)
Quote: Oh, and maybe make it slightly darker? Wine is usually a slightly deeper red (because its not so well lit lol)
I will tweak the color / brightness of the whine a little. Play with the sliders and see what works best. As the light came from behind the white glass in the background the overall look was a little brighter than what we are used to.
Quote: Perhaps a black card on the right side to give a delineated edge.
Greg, I actually used black cards (check out the stand of the glass). But you are right. The right edge isn't as defined as it should be. Luckily this is an editing flaw. The original image does have the information, so I'll tweak that part of the image again. One of my biggest problem is actually working with a not calibrate (I suppose not even calibratable) and glossy laptop screen :-/
Again, thanks for your help!
