Tim, Here is the response I received from Daniele: Dear Tim, Hal, Jonathan and Marcus, thank all of you for your answers! Indeed I was using the last version of WinFract (for Marcus, I'm using this version http://www.fractint.org/ftp/current/windows/ ). I didn't know that the DOS Fractint was supporting such higher resolution. This represents a good solution. Thank you Hal for your detailed instructions. Dear Jonathan, if you have a modified version of WinFract which reaches a something near to a 4096x4096 I really would appreciate it, even if is not bugless. Could you send it to me?
Does the "pieces" feature still work? As a I recall a PAR files is created that generates parts of an image that can be pieced together with an outboard utility. I'm not sure what limitations the utility has, but it wouldn't be too hard to resurrect it and, I would think, make very large images. Of course once I would have said 3072x2304 was more than very large!
Yes, the "pieces" feature is still in Fractint. When I increased the artificial limit in WinFract to 4096x4096, I was able to generate an image of maximum size 4087x4087. Increasing the artificial limit to 8192x8192 made no difference.
I haven't experimented for a very long time, but I seem to recall that color combinations that look good on the screen are too dark and saturated to print.
It has been a long time for me, as well. I don't recall a specific problem with the colors, other than the two images never match. Even with the color matching in Windows with the monitor and printer color profiles set up, the pictures (photos) I print don't always match the screen image. Jonathan
