I've made my first attempts at night time photography with 35mm Ilford Delta 3200. Two example images are posted in the Technical Gallery. The film was developed in Pyrocat HD diluted 1:1:150 with semi-stand agitation for 20 min, with the hopes of reigning in the extreme contrast range of the subjects. The resulting grain was enormous with grain 'clods' visible under the focusing magnifier. What factors may have contributed to these results and what film/exposure/development options are available to minimize these effects? Thanks for your suggestions and help.
