I'm in the process of developing sheets from this summer.
I read that Rollei RPX25 had extended red sensitivity, but never thought more about it.
But then I shot some subjects on my trip to the mountains on both RPX25 and Fomapan 400 or HP5+.
And the difference is obvious.
And interesting for the different creative options it opens up.

So I thought I'd share.

Same setup on my Chamonix 45H-1 with red filter. Both shoot with a few minutes in-between. Developed in Xtol 1+1.
