5×7 Dry Plate | Converted to Positive Now, the image scanned in the last step is a scanned negative. Several methods will convert the scanned negative into a positive for printing. For me, using the “curves” function in Aperture worked the easiest and fastest. Set the “Range” to “Normal” before dragging the control points on the RGB curve up and down. Drag the top right corner to bottom right, and drag bottom left to top left, effectively inverting the curve. See 5×7 Dry Plate | a 7 Image Story for a description of all the restoration steps taken for this image.
