<p>I'm looking for an ultra-fine grain developer suitable for Minox 8x11. So far the developers I've used are ID-11, Perceptual and R09. While the results have been nice, they aren't fine-grained and I've seen some excellent results out there.</p>
<p>The films I use are Ilford Delta 100 & 400, Pan F+ 50, Fujifilm Acros 100 and sometimes Rollei Retro 80s.</p>
<p>Can anyone recommend anything easy to buy or perhaps make? For example, is Spur HRX any good?</p>
<p>Thank you!</p>
