Re: [APML]: 37 films tested (was Gold Max)

[konomi@mail.geocities.com]

A very nice study indeed,  and I must express my suprise at the poor 
results of the Gold Max film.  I have a couple nice shots of albeit 
bright objects that I took for 15 minutes.  I look forward to trying 
the other films anticipating even better results!

But could you explain the chart below a little more, and precisely 
how you determined the values of stop speed loss?  

> Kodak Royal Gold 1000    (One stop speed loss in two minutes)
> Kodak PJ400              (2/3 stop   "        "       "     )
> Kodak PMZ                (1/2 stop   "        "       "     )
> Kodak PJC-1              (One stop   "        "       "     )
> Fuji Super G 100         (1/3 stop   "        "       "     )

Thanks for the useful study!

Cheers,

Scott
