What I have sent in as my first print was a photo of the John F. Kenndey Library shot on Ektachrome 100 Plus. From here on in, 90% of my Ilfochromes will be from Kodachrome (if I am happy with them). I did not request any sort of contrast masking. Here is the shot that I sent in http://www.flickr.com/photos/35mmslides/3488649696/
