Ektalure was the last of Kodak's line of warm-toned portrait papers. It has a shorter tonal range than other enlarging papers, and is made only in one grade. It has not been made in about 10 years or so, and any that has not been frozen may show some fog.
When processed with a warm-tone print developer and toned in dilute selenium toner, it produces beautiful cool chocolate-brown tones. Adding 5 grams of potassium bromide to a liter of working strength print developer should both inhibit fog and increase the warmth of the tones. It is a slow paper so enlarging will take a little more exposure than for faster papers, and it needs a full 5 minutes of fixing in fresh fixer with frequent agitation. Rinse it in a running water bath for a few minutes after fixing and before looking at it in room light. It changes. Be sure to keep all your developing solutions at the same temperature - the paper can get very coarse "pepper grain" if solutions go from hot to cold.
Ektalure was designed with studio portraiture in mind. Its short tonal scale helps separate delicate skin tones. It's a beautiful paper. There is no reason not to use it for other purposes, just be aware that you may not be able to render adequate shadow detail in landscapes without adjusting your film exposure and development.
