I've used delta 3200 a lot for natural light portrait work.

It DOES have a disconcerting amount of base fog. Try to print your negatives before you give up on them.
As others have said, shoot at 1600 and develop at times recommended for 3200. DDX works great for this film. I scored many bottles of the stock at a low low price when the local college stopped offering darkroom courses. DO NOT use Rodinal unless you want golf ball sized grain. I've never tried HC110 with this film, but I'd be hesitant.

You've got the film, so you might as well play with it. Don't shoot a wedding, your favorite rock star, or a precious newborn with it until you are happy with results from at least a couple of rolls just shot around the house.

Have fun!
