Thank you, Antti and striwari,
I expose the Tmax @ 200 ISO and develope in Perceptol 1+2 @ 23 degrees C for 9 minutes. I scan with an Epson v600 in professional modus with all settings to "OFF", but with level adjustments, @ 4800 dpi. Then I apply some (2 or 3) "sharpen more" filters in Photoshop Elements 2.
Erik.
