Article by Geoffrey Crawley (October 2000)

The results of tests on the new Ilford Delta 400 Pro compared with its predecessor 400 Delta Pro and the worthy and still popular HP5 were published in BJP recently (20 September). The conclusion was that the new bi-pack emulsion was superior in speed to the previous 400 Delta by 0.5EV, showed marginally finer grain and better pushability. Its gain in speed and pushability over HP5 was...

Thanks John. Did I ever send you the original 1961/62 papers from the BJP? This was where he made his name, so to speak.

Hello Murray. I have only just noticed this comment from you. No, you haven't sent those to me. It would be interesting if you could. No hurry, and don't go to too much trouble. My email address you already have.

I'm in the process of choosing a 35mm 400 speed film to take to Italy for 6 weeks. I prefer 120 but I have to minimise carrying stuff. (there's also a risk of theft, too!)

I'm tempted to choose Delta 400. I want to get good enlargements. I'm dubious about Crawley seeming to say that there's not much difference compared to HP5+. I'm still using Neopan400 in 120 size, but I thought the "new tech" films in 35mm might be better.

What do you think?

 

[Murray Kelly]

OK - it's on the way.

I agree about the tabular grain films. No personal experience esp. with 120 but the consensus seems to favour them over the old. It's the 'look' that doesn't suit all. I still dwell in the past and shoot nearly all slow film.

Cheers
Murray

Sadly Mr. Crawley died almost a year ago, I was an admirer of his work for for more than forty years, and I learned a great deal from his articles in the various publications he wrote for, his vast scientific knowledge and expertise will be sorely missed by photographers all over the World http://www.telegraph.co.uk/news/obituaries/science-obituaries/8115973/Geoffrey-Crawley.html

I enjoyed reading this. Can anyone point me to current writings about the new T-Max 400 in the 35mm version? The newest version increases development times. T-Max has been my film of choice since I comapared it to Tri-X years ago.
