I attempted to print my Kodak Gold negatives last night. I used a DeVere 504 enlarger which has a very powerful lamp, perhaps of 250 Watts. The prints I produced with the aperture of the enlarger lens fully open at f2.8, needed at least two minutes exposure. The contrast was very low, no doubt affected by the dark orange/brown base colour of the negatives. Using maximum Magenta filtration improved the situation, but still didn't achieve acceptable contrast. As a comparison, a standard B&W negative printed at the same aperture, and to the same size, would have required an exposure of 1-2 seconds on this enlarger. Luke's enlarger has the advantage of a condenser light source which should improve contrast, but perhaps only a 75Watt bulb, which could mean exposure times running into days! This sort of negative won't show the true capabilities of the enlarger. I would strongly recommend trying a conventional B&W film first before experimenting with the colour films. That way you will have a better idea of how the enlarger performs.
Good luck, though, however you decide to make negatives, and please let us know how you get on.
Alex.

Wow, Alex, 250W, f2.8 and 2 mins". If you get fed-up trying to print the negs then you can always wear them in place of a bulletproof vest

I applaud Luke's desire to experiment but like you I hope he doesn't draw the wrong conclusions about B&W printing from this.
