Using slide film was tough. There was the exposure accuracy to consider, the waiting for processing (1 week for Kodachrome) and of course the not insignificant question of what to do with your slides when done. Of course the pay off at this time was the best quality colour image available.
Negative film was more immediate and more flexible/forgiving and black and white gave you the (illusion) of complete control.
A passing thought. If I am happy with the jpeg files form the Pen F and they give me HDR, HiRes and other multi file options as well as built in lens corrections, then could (should) I switch to jpeg for landscapes.
This would in effect be the same as shooting slide film without all of the problems mentioned above. In fact it would reduce a few issues I have now with file storage and processing. Is it too limiting if I intend to process aggressively?
