General question related to your experience using Ilford Delta 3200 pulled to 1600 ISO or lower.

Which developer chemistry do you have best experience/results with, and do you pull exposure lower than 1600 ISO? I have seen comments related to using the product @ 1000 ISO, but I use a lab that uses a "+1, -1" pricing for push/pull services when processing, and to consistently expect results from a lab I think you need to follow their practices as much as possible.

Thoughts and comments, all are welcome. I would be interested in comments related to grain structure based on pulling exposure. And if you use both 35mm and MF, any comments related to format differences would be great also.

Regards,
