Specifically the background tone and any border you may use. The gallery background is quite dark neutral grey (a good thing). A lighter border can make the images 'pop' (which is why all muy posts tend to include that). Another trick is a very light grey border which fools you into seeing brighter highlights too. The best example that I know of to illustrate how adjacent tones affect your perception is here. http://web.mit.edu/persci/people/adelson/checkershadow_illusion.html Cheers Geoff http://www.pbase.com/hoppyman On 23 April 2010 12:05, Jim Nichols <jhnichols at lighttube.net> wrote: > Ken, > > First, let me say that my monitor is not scientifically calibrated. > However, when I process an image for uploading to the LUG gallery, I > normally leave it a little on the dark side, because I have found that they > tend to lighten up a bit when they appear in the gallery. > > I resize to 800-1000 pixels per long side, save as 8-bit jpg level 12, and > upload as sRGB. > > YMMV > > Jim Nichols > Tullahoma, TN USA > ----- Original Message ----- From: "Ken Carney" <kcarney1 at cox.net> > To: "Leica Users Group" <lug at leica-users.org> > Sent: Thursday, April 22, 2010 6:35 PM > Subject: [Leica] question on gallery reproduction > > > I notice that when I upload a b&w image to the gallery, it seems to be >> lighter and not as contrasty as the original.
