Ferrania P30 With Diafine

Ferrania P30 With Diafine

A test to check the expose of P30 in Diafine and then scan on an Imacon II.
After running a wide range of tests It looks like shooting P30 at ISO 100 will yield the results I want. (Everyone has a different work flow, so I am only claiming that this works for me.)

Develop 4+4 (a little longer than the standard 3 min per Cal's recommendation)- Invert 30 sec. 1St, 2 times invert every min. No Presoak, no rinse between, Rinse before Fix, Wash 15 min.

The thing I like about this is I get a full range curve, with no blacks or highlights lost, but a smooth drop off down to zero on both ends of the curve.

Ferrania P30 With Diafine

It seems like at an ISO of 125 in Diafine shadow detail starts to get lost, and the curve compressed.

In all of these, the ISO was set with either a incident reading, or a reflective reading off of the middle gray.

Steve,

I do 2 inversions per minute, and that also includes the start. I do no initial 30 seconds continuous at the start.

Diafine recommends three inversions per minute, and no initial continuous agitation either.

You are adding density by the continuous aggitation. I add density by exposure and longer development.

Understand that I'm trying to maximize shadow detail and also the compensating effect. By minimizing agitation and extending development I'm trying to be more like stand development with slowing down development, making development gentler, and extending the duration.

Cal,
Thanks, I will back off the 30 sec, and use two inversions at the start as well.

Steve,

Your results are interesting. In a way you increased development by increasing agitation. It took me a while to figure out the inverse that by cutting agitation I also was cutting down the development.

To gain density I extended development.

It also seems that gentler development promotes smaller grain as a bonus.

Sorry for creating a reason for more testing. LOL. Anyways just do what is good for you. Since you have an Imacon your best negative will be different than mine for wet printing.

Cal,
There really wasn't that much agitation at the front, but I will dial it back. Maybe 4 inversions at the most.
But, I will dial it back.

Steve,

I don't really understand how to interpete the differences between your 80 and 100 ISO tests. What makes you think 100 is better.

I would think the longer exposure would record more shadow detail, but understand I tend to be aggressive. Is it too much, or is it because the Imacon likes the thinner negative?

Anyways this makes sense to me, but is my thinking correct?

Cal
 
I still have to develop my third roll that Steve above gifted me.

Somehow I got gifted yet another roll of P30, so far I have been recieved 4 P30 donations, and I am not an original kickstarter.

In a way I'm looking at this situation like "Divine Intervention." This free P30 is kinda remarkable. Can't wait till P30 in 120 is available. It seems well suited for my style and definitely has a look I love.

Ferrania says it's coming, along with 4X5 too, but no time table. They're still in the "alpha" phase of making film.

Jim,

Lately I have been enjoying the retro-vibe of Kodak 5222. Although rated at 250 ISO, I shoot it at 400 ISO and dip in Diafine 4+4. The negatives have the blacks that are so urban and defines the grit, filth and pollution I see everyday.

It would be so great to have a similar film in 120 or better yet 70mm. Know that I have a Linhof Tech IV that is as old as me and I'm going to be 60 soon. I also have a Linhof Tech V that begs to be shot with a retro style film.

I surely will shoot mucho P30. I love the distinct look and it suits my style.

Go-120-Go.

If everything goes well with roll three, I'll likely dip roll 4 in DDX.

Cal
 
Is it an illusion (low res scans ?) but highlights are seriously prone to block. In all previous shots, there is no texture at all in whites.
Or is it D76 ?
 
P30 definitely has a distinct look, with dense highlights and deep blacks, without sacrificing the mid-tones. I've found this to be the case so far when printing at "normal" contrast settings in the darkroom. Probably the majority of the examples on the web right now are from film scans, which I would not always rely on too much for showing the true nature of this film. A lot of folks out there have their scanner settings all over the place. There's still a lot of testing at different ISO's and with different developers, but I think most of the folks shooting with P30 have been pretty happy with it.

With darkroom prints, I haven't had any problem pulling details from the highlights or losing detail in the shadows. I think Mackinaw's example photos at the beginning of this thread are pretty accurate to what I've seen.

What exactly is a point & shoot camera? Glad you asked!The Kodak of 1888 may have been the first, and even Leica got into the act!
