Kodak Professional Portra 400BW - Expired

I exposed another expired 35mm roll of Kodak Portra 400 BW.

I'm unsure why or how it happened, but I exposed almost an entire cartridge of expired Kodak Professional Portra 400BW with pictures of my orange tabby, Alphonso Mango. I had written "snow day" in my notes, but when I looked at the scans, I realised that I had also written the same thing on the notes for the expired Ilford HP5 400 I had exposed the previous day. I intended to expose both cartridges from the box of expired 35mm film during the snow. But ... I didn't.

Kodak Professional Portra 400BW was a multi-purpose chromogenic black and white negative film designed to be processed in standard C-41 chemistry alongside rolls of colour negative film and printed on traditional colour paper. It was developed like a colour-negative film in the C-41 process and delivered monochrome images like a black-and-white film. The film was intended for exposure with daylight, electronic flash, and artificial illumination. Kodak Professional Portra 400BWW was a versatile film for 35mm and medium format cameras. It was made with a Kodak T-Grain emulsion and had a wide exposure latitude. Production of the Kodak Portra 400BW was discontinued and replaced with Kodak Professional BW400CN, which was also discontinued. This film incorporated Kodak T-GRAIN® emulsions, which provided wonderful grain and sharpness at a relatively high speed. This film was used for portrait and wedding applications and many commercial applications.

The first time I used Kodak Porta 400BW, I exposed it at box speed. I realised then that I needed to overexpose the expired film. I exposed this 35mm roll of Kodak Professional Portra 400BW at ISO 100. The results are much better. But I think ISO 160 may have produced better results.

The film cartridge was developed at Boutique Photo Lab and scanned on my Epson Perfection V600 with VueScan 9. I processed the negative scans using Negatvibe Lab Pro, adjusted the exposure by -1/3 EV in Adobe Lightroom and cropped out the film borders.
