You think your a good retoucher. Take away your Mac. Take away Photoshop. Take away your Wacom. Now this is real retouching.
Looks easy right?
I've shot a lot of film over the years. This image was taken over 30 years ago. Retouching 4x5 negatives was not easy but could be done. Retouching 120 negatives would drive you to drink. If you even thought of working on 35mm you should be locked up. The negative was inserted into a carrier that held it in place and the magnifier was swung into position. When the machine was turned on it would vibrate the film so that you would move the pencil very little and the vibration would do the work. One of the knobs adjusted the vibrating and the other the intensity of the light behind the negative. Think about this image the next time you use the clone tool.
