printing SX-70 pictures in the darkroom

One of the most exciting uses of SX-70 film is using it in the darkroom to print directly from positives (slides). Here's a how-to:

1) Insert the transparency in the enlarger. For best results, remove it from its mount, or use a special carrier made for mounted slides. If you are printing from an instant slide, place it in the carrier emulsion side up. (If you are working with a conventional slide, the emulsion should face downward.) Clean the slide with an antistatic brush. Place the carrier in the enlarger.

2) Compose the image. One of the advantages of projection printing is that it allows you to reduce, enlarge, or crop the image. Position the film pack, slipping a white card into the pack for a focusing aid. Mark the position of the pack with tape or something tactile which you can find in the dark and lock the focus.

3) Make the exposure. Turn off all the lights, since SX-70 is panchromatic. Position your film pack with the dark slide cardboard removed by using your tape or guides. Exposure will vary depending on the individual variables of your enlarger and image. Create a test strip. Aim for an exposure of 5-10 seconds for best color balance and control.

4) Process the film. While still in the darkroom, insert the film pack into the camera. This will cause the film to eject and begin processing.

5)Evaluate and adjust accordingly. Remember that the print you are viewing is from a positive. If it's too light, it's over exposed. If it's too dark, it's underexposed.
