And you can shoot Acros with the Wratten 29 filter for a whopping -8 stops.

I think I'll get a roll of the stuff and play with it. The idea of shooting super-slow daytime shots without requiring a ND filter seems interesting to me.

I don't have my LX with me at the moment, I think the internal light meter can be set to ISO 6.
I'll have to check my Gossen lightmeter to see if I can use the native 1.6.

The FPP store has 1.6 ASA color film in a bulk roll.

I've been doing C41 at home and this looks like a fun emulsion to try.

Your favorite 120 (6x7) negative holder for Epson 800 or equivalent

I have used it with a flatbed scanner and it worked well, once I shimmed it with some post-it notes to better grab film that wanted to curl up. This became less of an issue once I started developing my own film and could properly flatten it.

Where it really excelled was when I was using it with a lightbox and taking digital shots with a macro lens. It held the negative and allowed fast repositioning of the film strip.

As you can see, there are openings that allow you to feed uncut film through the device.

The working distance for any reversed lens will be the flange distance. Thus, 46 mm for Pentax.

I've used the lomography digitaliza (DigitaLIZA 120 Scanning Mask Lomography Shop). It does a good job of holding the negatives flat. It can show the edges of the film if you want to see the manufacturer marks.

What was the bit range of the original tiff scans (not the drum scans). Were they 8-bit and then saved to 16 bit files? That would explain the over contrast look compared to the drum scans.

Film MF or Digital K1
Posted By smigol

I have both the K1 and several 67 bodies and lenses.

What I've enjoyed about the 67 is the patience it requires for shooting. You slow down, consider each shot.

What I enjoy about the K1 is the reflex-like ability to shoot with impunity.

Both have their drawbacks.

The film is the limitation of the scan size. If I shoot a high-ISO film, the detail available in the K1 will outshine the film. The reverse is true for a nice slow ISO film - digital tends to break down into posterization of discrete colors while film renders the transition from sharp to soft much smoother.

I process my own film and scan it, so that removes the hurdle of going through a third party for developing. However, this puts the hurdle squarely in my own path, meaning that I must ensure that I have the chemicals, time to do the processing, and getting good scans.

A nice benefit of actually following people on flickr is that they're starting to offer suggestions. I've found some really nice work this way. Some are inspiring, others are simply neat. It's changed my opinion about clicking the follow button - now I do it more often.

I've used them for several rolls. I like their flexibility with push and pull. Prices are good.

The scans are nice - they've been able to get useful data from underexposed negs - better than I have.

The DA 14mm isn't full frame.

But then, the IRIX 15mm is and cheaper, to boot.

I received a response from Sigma:




To me, this means that no new Sigma design lenses will support K mount. Seems a bit restrictive, but I can appreciate the business choice.

I see that Sigma is releasing a new lens:

What's stopping them from releasing it in K mount, too? Is there a dimension limitation?

One thing that I've noticed with the cold shoe handle is that some flashes will ground out on the metal with the central contact. A piece of cello tape will help keep this from happening.

Filters for shooting the Aug 21 solar eclipse...
Posted By smigol

The duration of the exposure for the landscape shot is not long enough to damage the sensor. However, framing the shot will expose the inside of the camera to a buildup of heat. This could cause harm to the shutter or sensor.

See this link for examples of camera damage:
Is it dangerous to take pictures of the sun without any filter? - Photography Stack Exchange

Also, if you intend to show detail on the sun surface, you need to attenuate the light level to have reasonably useful sharpness (f16 and beyond will give diffusion) and shutter speeds.

You will need a filter that will dim the light from the sun, plus reject all heat.

Baader sells film that you can cut to fit common filter sizes to put on your lenses.

67 power requirements question

I'm familiar with the apparatus and I have the kit. It's a hassle to use in the dark unless your muscle memory has been well-trained. When lack of sleep starts kicking in on the second or third night at a dark sky site, trying to remember which cable to press in what order as well as figuring out the sounds of the camera can be frustrating.

I checked in the manual for the 67 and found a slightly different piece of advice that noted that the drift happens when the camera is set aside with a cocked shutter. My guess is that friction alone can't hold the tension and the shutter may fail to trigger with the proper speed.

Either way, it's a good idea to never leave a camera cocked when not actively shooting.

67 power requirements question

I've been thinking about powering a 67 camera from USB (5v) when I do astrophotography. The stock camera battery runs at 6v when new, dropping into 5v for most of its life, making me think that I could rig up an adapter pretty easily.

I currently have an external battery pack with 4 AA NiMH battteries and this does work well, I just am interested in seeing if I can remove the need for the pack and just tap off the USB hub that I already have.

Thoughts? Has anyone else ever done this?
