Dear Colleagues,

 

I thank you for your very valuable comments. As I had feared, the major effect is dust. I do use "canned air" to blow away dust from both the print and the scanner glass. Apparently it is not effective. Perhaps the large surfaces hold too large of a charge of static electricity.

 

Does anyone know whether it is possible to access the underside of the scanner glass on the HP 8200?

Les:

 

Thanks. I will try to pose an example. The effect is difficult to see unless one uses Photoshop to enlarge the

image.

Bruce:

 

The effect is worse when I use matte-finish paper, because the scanner records the texture on the surface, which

gives by itself a "salt-pepper" appearance.

I use conventional medium-format equipment to record portraits in my studio. I use a black backdrop. To make

digital representations, I scan 8- x 10-inch glossy prints using a HP scanjet 8200 at a resolution of 400 pixel

per inch.

 

The problem is that the scanned images have many, many tiny white spots ("salt-pepper" appearance) in the black

regions corresponding to the black backdrop. Although a few of these spots may arise from dust, most do not

appear in the original scanned print. The effect may be digital noise caused by the scanner, but I am not sure

about that. It is extremely tedious to remove these spots. Have you seen this effect? What is the best way to

eliminate it?

 

I thank you for any help that you can provide.

Gary

Thanks Aaron. Yes after I posted this question, I tried reading the manual. And sure enough the dioptor adjustment corrected the problem. So the old adage has merit: When in doubt read the instructions.

I have a Pentax 67II and several lenses. The images appear fuzzy in the prism

finder. The problem arises with all of my lenses. Thus I suspect that the

mirror and/or prism optics are misaligned.

 

Because, for most of my applications, e. g., architecture, I set the focus to

infinity, the lack of sharpness is not a problem. But I want to use the camera

in the studio, and therefore I must correct the problem.

 

Have you experienced this problem? If so could you recommend a course of action?

 

I thank you for your help. Gary L. Catchen

I am preparing a book of photographs of nude women. I am searching

for a publisher; or, in lieu of a publisher, a literary agent.

 

Do you have any recommendations?

 

I thank you in advance.

The developing times are typically short for Ilford Pan F. For commercial processors who use machines that run at higher temperatures than 68 F, the times are even shorter. This situation can lead to errors along with uneven or over development. You should talk to the processor before hand in order to learn whether the person has the appropriate expertise and experience. One solution (no pun intended) is to use a developer that can be diluted so that the developing times are longer. This practice should give more consistent results.

I noticed that, for some of my TMAX 100 in 120 size, the expiration

date passed three months ago. I have stored the film at room

temperature. Does anyone have experience using this film after the

expiration date has passed? Will the images be degraded, if I expose

the film?
