Atomic X film - a brief review

[AtlantaTerry]

I've done a brief review of New 55's Atomic X film here: http://thelargeformatblog.com/2016/0...-by-marc-morel

I hope it's useful!

Marc,

Would you mind discussing Atomic X film's reciprocity characteristics a little more than what was in your review? I've been trying some 4x5" Arista EDU Ultra 100 which has a terrible reputation in this area.

BTW, when it was readily available on eBay, I used a lot of Shanghai 4x5" film and liked it with either D-76 or HC-110.

Thanks,
Terry

Use New55's reciprocity compensation data as a starting point:

Forgot to add that like most manufacturers, the data may tend to be a bit too generous. That is what I have experienced with the many films that I have used over the years and why it is always a good idea to conduct your own tests.

OK, that's not too bad. Unlike Arista EDU Ultra 100 which really fades off.

Thanks.

I agree with Andrew - it's really important to do your own tests. From what I'm reading here and there, ISO's are ranging from 100 to 50 and 40 (and my 25) depending on developers, and reciprocity is vaguely 'as documented by New55', but again, may vary with your own process. If you CAN nail this down through testing, you may have yourself quite a useful and inexpensive film...!

Marc!
