RE: [APML] RG200 Alert



I'm wondering if I have gotten confused (likely 8-)
I just found some Royal Gold Select 200 stashed in the back of the fridge. The couple of boxes I have recently purchased was Royal Gold 200, does not say 'Select'.
 
Are these two different films and I never noticed?

Howard,
Very interesting that your film is marked with a -3 instead of the old -2.  Maybe Kodak changed the film markings later than they changed the actual film.  The new stuff I had was probably an early batch, but it definitely was marked -2.
 
Try hypering it about 4 times as long (or longer).  the old RG 200 from my tests and as reported by Tony Hallas really needs to be fully hypered to perform well.  My limited tests with the new RG 200 say the same thing.
 
If your film shows the expiration date on the box, I think the old film expired through the end of 2003.  The early new stuff had dates of expiration of Jan and Feb in 2004.  Maybe that will help tell which is which.

Don, you are absolutely correct: it has changed.
 
Just got back a roll of RG200 and it certainly is a new formulation. The negative strip says RB 200-3 where as the older stuff says 200-2 RB. Hypered 3 hrs @ 50c did nothing for the film. The exposure of 45 minutes was virtually absent of any red, very poor overall sensitivity.
 
Now I have to figure out which unused rolls I have that are the -2 and which are -3 . Any one have any ideas besides developing a test strip ?

I believe another great color negative film has been changed by the manufacturer - Kodak Royal Gold 200.  Film I bought in April for a test series hypered completely at 30°C in 36 hours with a characteristic rebate change.  That film is the best I've found to date. I bought additional rolls in late June (marked expire 2/2004) and that film doesn't hyper in 36 hours, it now takes 96 hours to get the same rebate change.  This new version has no change in the film markings, and has slightly less light sensitivity than the "older" film.  The new stuff hypered for me in 12 hours at 50°C, with light sensitivity better than the new 30° hyper, but less than the old 30° hyper.
 
It's still a great film, but I hate to loose anything in film capability.  From my tests, RG200 hypers best at 50°C.
 
Has anyone else observed or sensed a change in RG200?
