All, I need help to start developing my own Delta 100.

With the corona virus here in Belgium almost everything is closed and also my labo, and I’m stuck with about 40 - 4X5 negatives that must be ready before end of April. Scannend and one print.

So my local store (www.retrocamera.be) sells on-line Ilford Ilfotec DD-X does anyone have some experience with this, if so can you provide me quick/ dummy howto to develop my negatives.
And also what kind of fixer, and the total amount of liquids I need.

A lot of questions ....

Thanks
Patrick
