I have a Howtek SM 4500 and DPL Pro.

Welcome back!

Sandy, I am using DPL. And for whatever reason I find it better to scan on RGB and then convert in photoshop. Occasionally I go the gray route and after waiting an hour find that I don't like the...

Sandy,

Yes they were scanned RGB and the negs have a slight purple cast to them. That's probably the reason for the pink in the files.

I normally use the channel mixer to even that out and then...

Well I think that's the real test... The final printed image!

There are certainly many steps from film to print and each has its effects.

I still see a vast difference between 2000/13um...

Michael,

A few notes for you.

1. Use 1000ml of working solution in the 3010. Results will be better. 1 sheet or 10 you will want 1000ml.
2. Do not Photo flow in the 3010. Do it in an alternate...

Sandy,

I would be curious to know what scanner/software combination you used to perform your test. I just performed a similar test using medium format Pan F Plus and although I think I am now more...

Over at CERN they do it all the time. ;)

But you are right - 1um, or 1 micron, or 1 Micrometre is roughly 0.000039 inches. Multiply that by 6.3 and you get an 0.0002457 inch opening. How many...

Peter,



Well, yes but not 50% gray. It would be grayer than black or grayer than white but there is also multiple colors being recorded as well and various intensities of those primary colors....

Peter,

That may be semantics. But I would say no. There would be no "hardware interpolation". The scanner sees what it sees. By opening the aperture, you are simply showing the scanner something...

Sandy,

I'm not sure my position is that resolution is reduced. It's more the image itself becomes a bit softer. Like opening an aperture on a camera. Of course that's not an excellent comparison...

Sandy,

Considering your argument in terms of a 35mm verses a 6x7 negative of the same scene, the 35mm being shot at F8 and the 6x7 being shot at F5.6. Your argument theorizes that the 6x7 negative...

I'm not sure that last part would be correct. While the math is correct, there is no interpolation from the scanner. That is assuming we are talking about an Howtek/Aztek type.

By setting the...

Here is the Sussex County Courthouse which I took this weekend. Although I am generally ok with the image I am wondering what else I could have done to get the perspective better. I mean the upper...

From what I understand copyright protection applies the moment something is "Fixed In A Tangible Medium".

So a work must be recorded in some physical medium, whether on paper, canvas, disk, film,...

I'm in~! :)

I'm also in NJ and I send all of my color work to Edgar Praus. He does excellent work!

There are at least three sources in the US that specialize in photo chemicals. They are:


Artcraft Chemicals
Photographers Formulary
Bostik & Sullivan


It's a good idea to shop all three...

One must remember that Epson scanners are consumer products. Epson may be recommending this for no other reason than to avoid numerous customer calls complaining about backwards images.

However,...

For 1 Liter Undiluted

Water, 125F/52C 750 ml
Metol 7.5 g
Sodium Sulfite (anhydrous) 100 g
Water to make 1L

For 1.5 Liter Undiluted Multiply above by 1.5

Water, 125F/52C 1200 ml

Just one of my guitars... :p

It depends on whether there is any carbonate in your developer. What happenes is when a developer contains sodium carbonate, used to increase the pH of the devloper, gets placed into an acid bath -...

It's really quite simple....

Standard viewing distance is the viewing distance that "ALL" photographers agree upon. I remember when I started shooting I had to sign the contract obligating me to...

I thought Pyro wars were the result of all of those early 80's glimmer rock bands....? :p

Silly me...

Seriously, pyro is an interesting topic for B&W dev and I agree with "rdenney" that you can...

I think Mr DeFehr is confusing a successful test with an artists body of work. Ken, as I read the posts, was speaking of the successful test of his Diafine experiment and was happy with that success....

I have the Mod 54 and used it successfully for some time. I occasionally had uneven development where the film sheets get held into the holder and especially on even areas like the sky.

I have never used that combination however a Wratten No. 80A has a filter factor of 4. Which means you need to open up 2 stops. 160 opened up 2 stops is 40 ISO.

Yes you are correct and I will probably end up doing just that. However, I am also in the process of learning some of the chemical processes as well and in that regard it never hurts to ask too many...

OK I reread the Darkroom Cookbook and found "When sodium carbonate, ..., comes into contact with acid, carbon dioxide gas is released." For now I will assume that potassium carbonate does the same.

Thanks Richard. What I probably should have specified is that I am looking for an all around simple stop for film as I do not print but rather I scan my film.

So if I am using XTOL or D-23 to...

Hi All,

I’ve read that Sandy King uses a half strength stop bath for Pyrocat HD.

I am almost out of my ILFOSTOP which I am diluting 1:40, which I assume meets his definition of half strength,...

I would second the Epson Hot Press. I like the Hot Press Bright a little better than the Natural but give either a go! It works with the Matt Black...

I can't tell you what it is, but I know it when I see it!

Nicely done! :)
