Here's a hard question: Since I have not made a colour picture in over forty years this pair of Pandani leaves and Lichen challenges me to pick one but I'm not sure how. Both look very good. What criteria does the colour photographer invoke to select the right film for this subject?
Don't go there Maris, (you know you don't want to)
As you well know 'black & white is the best colour you can get'.
I am from an era and a paradigm where Reversal ruled, but the range of reversal stocks is reduced as is the choice of labs. Colour neg materials are alien to me.
Back when you could I reached for the silver box of Agfa followed by 'Old Yella', which became de rigeur when I eascaped from live subject. Green boxes were selected for exaggerated impact — motif-driven. Mark's pic is very much in line with what I find enormously appealing ..... an essentially monochrome target with spots of colour as accent. That said, I'd be looking at how an emulsion deals with neutrals. Note that there is a warmth to the Pandanus in the Provia which (with full respect to Mark)I don't favour in the comparison offered. Then comes the matter of how you intend to display the fruits of your travails.
Right towards the end of film as a commercial staple Fuji blew me away with Astia which was SO accurate in its rendition that I used to call it "the best Kodak film that Kodak never produced.
