Unknown Film in Bulk Loader

*Generally*, if the emulsion side of the film is tan, it is a color film...if gray, B/W.
Fastest way to find out would be to spool off a 10-12 exposure roll into a cassette, and without exposing the film, process it in black & white chemicals for 10 minutes @68°F.
You should get an answer after the film is fixed. You can read the film edge printing, whether it's color or B/W film.

So I used my Canon EOS 620 to take photos at ISO 100, 200, 400 on automatic with the same scene. I just finished developing the film as ISO 400 with Arista chemicals and I have images! So I believe it is B&H. Now how do I determine the ISO of the film?

As others suggest, shoot several frames (preferably of a low-contrast scene) bracketing your exposures at say EI 50, 100 and 200 and develop the film. If there are no edge marks you'll still know the approximate speed of the film.

I assume You mean b/w. I suggest taking different exposures with different ISO on the same roll and develop for your usual developer /time. Check which ISo give you the image you like better. I usually do D-76 stock for 7 minutes.

I received an Alden 74 daylight bulk film loader with film in it. What steps do I take to find out if the film is color or B&W? If is it B&W what are the steps to figure out the ISO? I can develop B&W film in only.

Thank you! It is Ilford HP5 plus ISO 400.
