Don't worry about the theory behind this. Just do it.
Step 1 (assuming you've got a pic loaded in Photoshop) Levels > Autolevels (Shriek!)
Step 2 Image > Mode > Lab Colors
Step 3 Image > Adustments > Contrast. Set Contrast to - 30. (minus 30)
Step 4 In the Channels tab on the right (next to the Layers tab) select "a". Your image will look terrible -- all gray. Don't worry about it. Go to Image > Adjustments > Levels and slide the INPUT slider on the LEFT from 0 to +30 (positive 30). Slide the INPUT slider on the RIGHT from 255 to 225 (subtracting 30). (Leave the middle slider alone at default "1").
Step 5. Repeat the steps above except this time select the "b" channel.
Step 6. Select LAB in the Channels tab (above Lightness, a, b). This will show you your "Cron" image.
Step 7 (Optional if you want to save as jpeg or convert to black and white) Return to RGB mode by selecting Image > Mode > RGB
If you want color, you're done. But if you want...

Black and White Conversion.
Step 8 (You must work in RGB mode, since you can't access the Channel Mixer in LAB mode) Image > Adjustment > Channel Mixer Tri-X Emulation: Output gray, Red = +25, Green = +35, Blue = +40. Make sure you have the "Monochrome" box checked.
Or
Ilford FP4 Emulation: Output gray, Red = +28, Green = +41, Blue = +31. Make sure you have the "Monochrome" box checked.
Or
T-Max 100 Emulation: Output gray, Red = +23, Green = +37, Blue = +39. Make sure you have the "Monochrome" box checked.
Or
T-Max 400 Emulation: Output gray, Red = +27, Green = +36, Blue = +37. Make sure you have the "Monochrome" box checked.
Or
AgfaPan25: Output gray, Red = +25, Green = +39, Blue = +36. Make sure you have the "Monochrome" box checked.
That's enough black and white film stock conversions. Ain't got all day.
You're welcome.
