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...

  1. Place on your screen outside the image area.
  2. Expose the screen.
  3. Wash out the screen like normal.
  4. You should be left with 7 solid steps.
  5. If you are left with 5 the screen is underexposed, risking pinholes or premature breakdown
  6. If you have 9 the screen is overexposed, risking loss of fine detail.
