    It depends on the results you want. A higher dilution increase edge sharpness but also a slight increase of grain. If you use sheet film (where grain is hardly an issue) you will maybe prefer a higher dilution even if you use a normal tank for development.

    Grain is fine by me. And a higher dilution is always good as then I only need a smaller quantity of chemicals. The problem is dev time. How do I come up with times for uncommon dilutions?

    Check this german document, it contains development times for X-tol (similar to Excel) with different dilutions. Other dilutions is not published anymore in english:

    read down the page here as well:
    http://www.covingtoninnovations.com/xtol/

    I made 3 negs of same subject under normal light condition and developed with times from the chart as a starting point and then did some small adjustment until the negative was perfect, making it printable as a normal grade 2 image.

    Very close to each other. Only the densito meter shows some small differences. Further slightly more grain with Excel W27 but this is in the margin.

    In Europe: Xtol (5 Ltr.) : Eur. 10,- , Excel (1 Ltr.) 2,50 but sometimes for 35mm a 1 Liter package can be more practical. Same short shelf life 4 months - 6 months and heavily depending of the quality of the water. Therefore demi - or destilled water adviced.

    wiggywag: Thanks for the links, you've very helpful

    RobertV: Thanks for the photo and advice, Robert. Of course, I use nothing but distilled or reverse-osmosis water to mix my chemicals..who knows what's floating around in my tap water. But damn, 10 Euros for 5 L of XTOL is cheap!
