Nice color saturation, perhaps a very slight blue color bias, tight grain. Looks like it might be a good substitute for Ektar.

What did you use to scan the images?

Finding the right color-balance is always difficult. I tried to match the look of the original slide.

For scanning I used my home made device, consisting of a nex 5n, a Rodagon 2.8/50 mounted with some extension rings, and a lighting table as illumination.

Best regards

Timo

Very interesting. I dupe my film with my NEX 7 and a 55/2.8 AIs Nikkor with extensions that get me real close to 1:1.

I've found print film to be rather hit and miss. Some emulsions I can get converted fairly easily, and others, no matter how hard I try, I can't get the color balance right -- Ektar, specifically. So I'm curious, how do you go about converting your negative dupes to look that good?

I chose Agfa precisa ct 100 because it is (was) the least expensive slide film and so it is relativly easy to scan.
You are absolutely right, ektar is quite hard to demask, usually I use a simple fotoshop action to remove the orange mask, often it works quite well, sometimes it doesn´t. I believe there are two major problems, lighting conditions while exposing the film, especially artifical (LED) ligth and the light used to enlight the negative while scanning, I believe my cheap lighting plate is so so in terms of it´s spectral qualities. Another problem is the "primary" white balance that has to beset before the negative is converted, when you fail in this first step, everything is ruined already.

best regards.
