On the Massive Dev Chart, there are two listed times for Delta 100 and Diafine, and they&#8217;re both 5+5. What&#8217;s surprising is that it&#8217;s the same time whether you rate the film at ASA-50 or ASA-100, an interesting change given that, most of the time, the speed rating is faster than the box speed, not slower. I went with my Nikon F5 and the 28mm f\/2.8 lens with the aperture set to f\/11. Then I used the EV adjustment control to move between the -2 to +2 using a remote release.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55415477693\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55415477693_c7177eb444_b.jpg\" width=\"1024\" height=\"118\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55414393562\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55414393562_0cde9b60a1_b.jpg\" width=\"1024\" height=\"115\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><\/p>\n<p>In the introduction, I mentioned that I was disappointed, and I still am, about this test. The disappointment comes down to one thing: the times stated that the 5+5 time is for both ASA-50 and ASA-100, so I figured that Delta 100 would perform better on the over-exposure side of the test and poorly on the under-exposure side. It appears that the opposite is true; the results speak for themselves. Delta 100 in this combination works up to two stops of under-exposure with great results at box speed. Could you recover the images on the over-exposure side? In some cases, yes, the one-stop over is easily fixed in post-processing, but the two-stop might need a bit more heavy-handed work.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55414393557\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55414393557_7b557e1400_b.jpg\" width=\"1024\" height=\"118\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55415532439\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55415532439_5c67b571df_b.jpg\" width=\"1024\" height=\"118\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><\/p>\n<p>Despite being disappointed in the test results, I was more disappointed that the data was wrong than that the image quality was. Delta 100 is an excellent film with lots of good things going for it, and I think that it helps with mitigating some of the disappointment. Even with the two-stops, you still get good images on the frames that work, with only a light touch in editing. If you feel that the contrast of TMax 100 is too harsh, then Delta 100 might be more your speed with a more middle-high contrast, and that isn&#8217;t changed even with the one-stop under-exposure, although it does get lower with the one-stop over-exposure. The edge sharpness is still excellent, and the grain structure isn&#8217;t too harsh, although there is a bit more visible grain, which isn&#8217;t a bad thing.<\/p>\n<p><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55415748395\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55415748395_12297a9005_b.jpg\" width=\"1024\" height=\"133\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><figure style=\"width: 1024px\" class=\"wp-caption aligncenter\"><a data-flickr-embed=\"true\" href=\"https:\/\/www.flickr.com\/photos\/axle81401\/55415532444\/in\/dateposted-public\/\" title=\"Extreme Film Review No.10 - Ilford Delta 100\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"https:\/\/live.staticflickr.com\/65535\/55415532444_51342d1f06_b.jpg\" width=\"1024\" height=\"132\" alt=\"Extreme Film Review No.10 - Ilford Delta 100\"\/><\/a><figcaption class=\"wp-caption-text\"><script async src=\"\/\/embedr.flickr.com\/assets\/client-code.js\" charset=\"utf-8\"><\/script>Nikon F5 &#8211; AF Nikkor 28mm 1:2.8 &#8211; Ilford Delta 100 (+\/- 2-Stops) &#8211; Diafine (Stock) 5:00 + 5:00 @ 20C<\/figcaption><\/figure><\/p>\n<p>Despite my disappointment, I did find out one thing through this test: don&#8217;t always trust the data.

I&#8217;m not sure what the results would be by dropping the time down to a 4+4 or 3+3, but that might clean up the overexposure; that&#8217;s a trial for a different time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>After seeing the results I got out of Kodak TMax 100, I had high hopes for Delta 100.
