It's less warm than the original PiezoBW, and slightly warmer than a cool/neutral silver print. I've never compared it to a warm silver print, but it may be close to that. I used to test and measure warming with my scanner. On that 256 scale, the FS would warm about 8 to 10 of 256 units. It then stabilizes. I don't know how to measure the time it takes. In the fade testing by 300 hours it had completed the warming. It's a question of how much light it receives. >I happen to like the warm look of a selenium-toned or platinum print, My selenium prints are not warm at all. So, that is paper dependent. In general the selenium prints have a bit of magenta in them that is not in FS. The FS inkset (pre-warming) is not as warm as platinum print, although they vary considerably depending on the developer used. After it warms, the FS is probably within the platinum print range. The original MIS quads were quite close to most of the platinum prints I saw on one trip where I did a survey of print tones with test strips in hand. Some of the most expensive platinum prints I saw in a Taos gallery were more like a dark sepia, however. >certainly wouldn't want to sell someone a print that was going to start fading >like a comfortable pair of jeans within, say, 5 or 10 years (behind glass, away >from direct sunlight). The fading isn't bad with FS. However, people will see the warming if the new and old, or long-term display and dark-storage prints are displayed side-by-side. >So because I like a warmer print, my only reasons for >considering FS-N would be if it truly is a more stable inkset. The FS and FS-N inksets fade at the same rate. The warming is much less with the FS-N, however. > Also, if regular FS >appears more brownish than selenium tone, It is warmer. I'd say more yellowish than brown, however. Although after warming, some call the look brown. > I might choose FS-N if it provides >a more traditional-photograph-like appearance in comparison to FS. The FS-N definitely looks better (under glass) next to my lightly-selenium-toned Kodak Polymax Fine Art prints. Have you considered the PiezoTone WN midtones with the FS black? It's the most stable medium warm inkset now. The PiezoTone Selenium midtones have a good tone, but it is definitely not a warm selenium. It's more like my Kodak silver prints and the FS-N, which is slightly cool. >I suppose that means that FS-N is really my only option then? >I'm not using the Piezography/R9 software, by the way. If you are using a hextone machine, then the Piezo inks don't lend themselves to Epson driver use -- unless you re-arrange the inkset. You can make an "FS-E" series equivalent from the PiezoTone inks by diluting the cyan and magenta for the light/photo positions. Or, you could just use cyan in both cyan and magenta positions and use magenta in both the light cyan and light magenta positions. You'd have to write your own curves, but such an inkset takes very little adjustment. I did this with the FS-N inkset once and it made quite a good way to go. You can even use just a grayscale workflow with the inkset, although mild partitioning still gets smoother tones. Paul http://www.PaulRoark.com
