Re: 4x5 field camera considerations

[karabog@xxxxxxxxxxxxx (Bogdan KARASEK)]

Hi,

Thank you very much for answering a question that I was going to bring up,
namely, preventing the film from fogging when in the film holders. One
question remains. When shooting IR in 35mm, one always resets the lens focus
to align with the red IR indicator on the lens barrel.  Since I use the
ground glass for focusing (an old Crown Graphic 4x5 bought for $200), how do
I go about resetting the focus for IR film?

Thanks,
Bogdan
