Too many years since I shot with a Nikon F4 and Hasselblad 500 C/M for portraits, weddings, aerial and macro. Eagerly returning to an old Love now. We used to store film under refrigeration; do I have to keep these small cards cold now? I will not miss the darkroom and am eager to sit in the light at a computer instead. Thanks to everyone in advance who will hopefully tutor an old dog.
