Do I need a recessed board?

Do I need a recessed bord if I use a Sinar F1 with a 90mm f/8 Super Angulon?

Do I need a bag bellow or the standard bellow is OK?

I'm a newbe in LF.

Thank you

a bag bellows would be helpful in this case but, if I remember correctly, it is not absolutely necessary.

Standard bellows will work with the amount of image circle you have with a 90/8 Super-Angulon, but you might find it handy to have a bag bellows. If your longest lens is 210mm, you could use a bag bellows for just about everything except close-up work with a 210mm.
