When making prints under an enlarger you might use graded filters to enhance your final picture
I have a Meopta 4 with colour head (3) and below is a table of the Ilford Grade numbers and corresponding Meopta Colour head settings to use.
| Ilford Grade | Meopta | |
| Y | M | |
| 0 | 75 | 12 |
| 0.5 | 55 | 16 |
| 1 | 42 | 21 |
| 1.5 | 35 | 27 |
| 2 | 27 | 35 |
| 2.5 | 21 | 40 |
| 3 | 15 | 45 |
| 3.5 | 9 | 56 |
| 4 | 3 | 67 |
| 4.5 | 0 | 97 |
| 5 | 0 | 97+ |
I have made bold, grades 0, 2.5 and 5 as these are the ones used most frequently in grading enlargement’s.
Most start with Ilford’s 2.5 grades in general and work back or forward from there.
Split grading is normally 0 then 5 to suit but more on this later.
I will be making a post and a video about using the Meopta 3 colour head but for now I hope this is of some use to you.
Like most things in photo enlargement and film development take all times and suggested setting as a starting point to refine down to setting best suited for you and your workflow.
