I find the SMC Pentax 67 200mm to be as sharp as any in the line with excellent color rendition. How are you liking the Superia 400 in 120. I got a few pro-packs I picked up some time ago and yet to shoot much of it. Looks good here.

A nice pair of images Doug. We still need to meet up sometime. I'll be on MDI this week shooting some Acros.

As always, thank you. I still surprise myself with how good the end product results. The difficulty of using traditional methods is overcome when the results are superior aestheticly to more modern methods.
I am currently working on a new set of B&W images using Acros. Preliminary results last year were promising, now I just have to try to stay awake on what are the shortest and latest nights of the year. Difficult for sure as I only have a little over three hours of true darkness, but that is where the gold is!
Thanks again and also thank you aurele |

Back to the photos.
Taken in late April when the summer Milky Way is in the early morning sky. Captured during the work week no less. Pentax 67 with 165 f/2.8 @ f/4.8 and Kodak E200 transparency pushed +1.5 stops. Exposure was 35 minutes under the dark skies of my home in East Sullivan, Maine. Tracking was done with an equatorial mounted telescope with camera mounted piggyback.
This image features the Milky Way of Sagittarius and southern Ophiuchus. The star clouds in the region are the best in the sky and are plainly visible to the unaided eye. Dark skies are a must to accomplish such a photograph without expensive filters. The prowess of film photography is still there, it just has to be harnessed.
Thanks for looking.

Thanks, The cliffs offer many photo opportunities. Glad I had the T-Max 400 as it was rather dark and the wind had everything moving, except the rock of course:D

The horizon is all fire from our Sun, and the rocks are illuminated by our Moon.
Overlooking Frenchmans Bay from Schoodic Point. Cadillac mountain is the highest point on Mount Desert Island and tallest mountain on the eastern seaboard north of Rio de Jeneiro.
I had not worked with E100G before and this was my one shot of this composition. Glad my instincts were working.

Yes, you would think that I would! I have very little Superia left, half a dozen rolls. Negative films tend to have less halation with the star images. This creates a finer image. That being said, E200 has wonderful properties, and I will use it for a project such as this next year.
Currently there is no b&w film that can create a similar image. Back in the day one would hypersensitize Kodak Technical Pan by baking it in a chamber of forming gas. A messy process, but it had tremendous recording power, especially in the desired red end of the spectrum, allowing capture of faint emission nebulae. Fuji Acros works great right out of the box, and even better when hypered, but it lacks a red response as it is orthopanchromatic. I wish it were otherwise. Red sensitive b&w films all have poor reciprocity.
I'm very much pleased by this faux b&w image as it comes very close to the old hypered TP look. The detail seen in this image would be very hard to accomplish with a DSLR, especially if you wanted to enlarge it to the size I mentioned.

The Milky Way from Scutum to Cepheus. I had longed dreamed of puting together such a mosaic. It was one long night in September, and on a work night no less! The first exposure started at 9:17 PM and the last exposure ended at 1:28 AM, the next morning. A equatorial mount allowed the camera to compensate for the Earth's rotation. The vertical length covers approximately 90 degrees, from near the horizon to overhead beyond the zenith.
A mosaic of 4 panels, each a 60 minute exposure using a Pentax 67 with 105mm f/2.4 lens at f/4.8, Fujicolor Superia 100. Due to unmanageable color gradiants I decided to convert to b&w to make it publishable.
The original could make a finely dtailed poster as tall as an interior wall, say 24" x 96"

O.k. One more.
Deep twilight at Schoodic Point, Maine, October 2011. An 8 minute exposure using the P67 with the newest version 55mm f/4 @ f/8 on Fujichrome RAP. The near full Moon illuminates the foreground. Gradients seen in the sky here are not on the original. That is thanks to my Epson V600 and .jpg compression.
Thanks for looking.

The ledges of Schoodic Point featured with Cadillac Mountain as a backdrop. Shot with the P67 & 300mm f/4 SMC Takumar under the light of the full Moon this past September. I recorded an exposure of 20 minutes at f/8 using Kodak E200 film. I had to go by the distance scale for focus and at f/8 left infinity slightly out of focus and possibly the closest foreground areas. Not bad for shooting in the blind.

An additional image taken the same full Moon night last November. The texture of the granite in moonlight is very seductive to me. This huge piece of granite is set up against the cliff leaving an opening to shoot through. The cliffs continue above and can be seen through the opening. One can also see star trails through the opening and the shadow gives away the Moon's position in the sky. That is an element I like to include in these images.
It is a very difficult area to set up a tripod and I have dinged my 67 body a few times just to get this shot. Shooting in the dark they say.

You can always shoot many days before and after the full Moon. You can record more star trails in these times when the Moon is less bright. You will need to expose longer of course. Reciprocity failure will be progressive in longer exposures.
I prefer f/8 for the Pentax 67 wide angle lenses (45,55, and 75) as they are very sharp at that aperture and do not vignette, yet offer bright enough images for reasonable exposures. Depth of field is good as well. I sometimes will stop down to F/9.5 or f/11 and recalculate my exposure if I need more depth of field.
At ISO 100 @ F/8

or after Full ------------------- ISO 100 Film (Acros, Provia, E100)
Full --------------------------- 10-20 Min

That is about right. With a Moon a day within full, 8 minutes at f/8 is standard. Due to the reciprocity curve for Acros you want to add a half-stop for a 12 minute exposure. I had filtered Moonlight with clouds and I exposed just a little longer. I go by feel as the moonlight brightens and fades. Fortunately Acros is forgiving here. 10 to 15 minutes is the range you want to be in. Seconds don't count on exposures this long. If you get within a minute or two your fine. Experience as well as trial and error helps. I tend to expose on the side of the longer times. Better to overexpose slightly than underexpose IMO.
