Saati 21 Step Sensitivity Guide
Tune in your burn times with this inexpensive but valuable tool.
Sometimes called a step wedge test, 21 step test, or exposure calculator.
Easy to use...
- Place on your screen outside the image area.
- Expose the screen.
- Wash out the screen like normal.
- You should be left with 7 solid steps.
- If you are left with 5 the screen is underexposed, risking pinholes or premature breakdown
- If you have 9 the screen is overexposed, risking loss of fine detail.
