Q: 1. Will this hold most common film holders? I see someone posted a link to a 2 pack for $100. I would like to try and limit the price if possible. Thank you.

A: Yes, any of the standard 4x5 cut film holders will work quite nicely. I have 15 or 20 of them that I load at one time, so there is no need to do so in the field.

Q: 2. I am familiar with using RC paper in a dark room... but never used 4x5 film.. How is the film/paper removed and developed... do you need your own darkroom?

A: Hi Joe:Perhaps the easiest and most straightforward way to process 4x5 film is to process it exactly the same as you would RC paper with the following exceptions:1. Processing must be done in complete darkness (no safelight). 2. Have the same three trays: developer, stop bath, and fixer. Use a film developer instead of a paper developer.3. Mixing a quart of developer for an 8x10 tray should be ample.4. Use a timer with fluorescent glow to time development. Follow the instructions for time listed for your particular developer/film combination. A website containing The Massive Development Chart online (do a search) might be helpful here.5. Wearing protective gloves, gently push the film around in the developer for the allotted time and then transfer to the stop bath, and then to the fixer. Remember to keep the lights off and be in complete darkness until you complete the fixer stage.As a suggestion, you might want to place the 8 x 10 developer tray into a 16 x 20 tray filled with water at 68 degrees. That will help to maintain the temp in the developer tray throughout the length of the process.Hope that helps you get started. All the best to you!

Q: 3. required accessories?

A: It needs a fairly sturdy tripod, and you will need some 4x5 film holders as you would any 4x5 camera. You don't need a Black Cat Exposure Guide, but I find mine handy in the field, and easy to use. The only other requirement is lots of patience!!!Hope this helps! Buy one and have tons O' fun!!!Mark

Q: 4. What is the pinhole diameter?

A: The pinhole is 1/64" for the Lensless 4 x 5" Pinhole Camera (Baltic Birch).

Q: 5. Would this pinhole camera accommodate the LomoGraflok 45 Instant Back?

A: The Lensless 4 x 5" Pinhole Camera (Baltic Birch) is not designed to accommodate an instant film back, which may be too thick to fit--the length and height is compatible, however, so you may be able to fix the camera to fit the instant film back in some way.

Q: 6. Which Film backs are compatible with this?

A: No film back needed , you mount the 4X5 film in the box

Q: 7. Why use a film holder with this camera?

A: There is no film holder needed for this camera, as you infer. The holders listed under accessories, are listed in error.

Q: 8. Does the camera come with the exposure calculator and the black box to hold exposed film , or it's just the camera ? I saw the kit here on B&H but I wouldn't use the film anyway , just the photo paper .

A: the Iford Obscura Pinhole Camera does not include an exposure calculator, or a black box to hold exposed media.

Q: 9. How do I determine my exposure using 400 speed film?

If you are using 400 speed film choose ISO 400 on the meter or camera. Then cross reference the reading vs the chart for f/230.I have another chart that shows me the additional time required because of the film's reciprocity failure rate. (This will be specific to the film you are using.)
