Push film 2 Stops or more is a way of creating a look you like or in situations were you need a higher ASA film. Pushing film means that you shoot at a faster ASA than the film’s original ASA. Most films can be pushed by 1 stop with out the need of any change in processing. For this reason there is no charge for a 1 stop push.
Example: Shooting Ilford HP5+ ASA400 @ ASA 1600. This is two stops of under exposure, resulting in 2 stops of pushing.
This method of shooting will result in the following:
- Increased grain.
- Increased contrast.
- Loss of details in shadows.
- Colour shift in colour films.
The following are the most popular:
- Ilford FP4+ ASA125 @ ASA250 (1 stop)
- Ilford FP4+ ASA125 @ ASA400 (2 stops)
- Ilford HP5+ ASA 400 @ ASA800 (1 stop)
- Ilford HP5+ ASA 400 @ ASA1600 (2 stops)
- Ilford HP5+ ASA 400 @ ASA3200 (3 stops)
- Kodak Tri X ASA 400 @ ASA800 (1 Stop)
- Kodak Tri X ASA 400 @ ASA1600 (2 Stops)
- Kodak Tri X ASA 400 @ ASA3200 (3 Stops)
**Not all films should be pushed, especially colour films.
