Finished Mahogany Lensboard...

Scott in Douglassville

>Well, I don't know if anyone's reading this or interested in the least, but it's the first woodworking project I've completed in over a year, so I'm a-postin' it.

To review, I've been making a lensboard for a rehabbed 8x10 Century. That'd be an old large format camera that shoots single 8"x10" sheet film. The lens mounts to the lensboard, which is then installed in the camera. The boards allow some flexibility in changing lenses.

This board's a three-piece one, mahogany with two breadboard ends, tiny lil' tongue-and-groove joints between:



The back is painted flat, flat black to minimize internal reflections. The T&G is a little easier to see before I cut the back recess.

Before:


After:


Sanded in a few coats of Waterlox to fill the pores a bit, and put a few more on top of that. Think I've got one more coat before I call it good.

Now I want to make one from walnut...

Thanks for looking.

Right nice, Scott!

>You may have a future as a lensboard builder - granted, a niche occupation, but I know there are a lot of folks getting back into large format photography, even as digital cameras become ubiquitous.

>Thanks, Bill. You know, if it'd help mitigate the expense of 4x5 (and soon, 5x7) sheet film, B&W chemistry, E6 chemistry, lenses, etc, etc, I'd be happy. Somehow, though, I don't think it's gonna put too big a dent in the equation... ;^)

>I wanna see a picture taken with the camera. An 8 X 10 negative would put any digital to shame for detail.

Well, it ain't 8x10, but...

Scott in Douglassville

>This is from a 4x5 which is a scant 1/4 the area of 8x10, but you can start to see (in a crappy scan from my $30 flatbed) the appeal of the larger formats (click the picture for a bigger version):

Great resolution

Stephen in Utah

>A friend of mine took this likeness. The exposure time was 1 minute 30 seconds so the patriarcial look comes from the situation. Wet plate ambrotype glass negative. It is mounted over a flat black background, velvet in this case. This is a compressed image, but it stands up under a microscope, NO grain.

There is a resurgance of old time photography. It is interesting that when cameras were first introduced you had to compose your picture at the back of the camera on ground glass. Then there was the view finder, then the Single Lens Reflex, then digital and again we are looking at the back of cameras to take a picture. Sometimes it is hard to improve upon the past.

OT - Looping back to the past as we progress

Bill Houghton, Sebastopol, CA

>Cingular is now running ads in this area (maybe everywhere, don't know) that they offer "fewer dropped calls than anyone else." A year or so ago, Sprint or someone was touting the clarity of their signal, that you could understand what people were saying.

I've commented to my wife more times than she wants to hear that the irony about telecommunications progress is that we're now thrilled when our phones work as well as they did 100 years ago.

>You don't know how many times I've been asked, whether shooting a Rolleiflex or my Super Speed Graphic, how many megapixels it is. I generally let whoever's asking peer on the gound glass, and their expressions are priceless. When they understand that the film is 4"x5", they get real interested. But they usually walk away clicking a few hundred pictures with their credit card-sized digicam.

The Mom-in-law has seen the light, though. Unfortunately, that means I have lots of printing to do for her... :^)

Just for grins

Dan Donaldson

>I did a bit of searching, and the sources that I found said that to get the rough equivalent to 8X10 film in a digital camera, it would be between 800 and 1000 megapixels depending on the particular film and lens.

Price for such a new-fangled (released in March '07) beast? $23000 US.

Be sure to post the walnut one too!

Installed in the camera...

Scott in Douglassville

>Well, the board got to its new home last week, and here it is in the Century 8x10:


And I've got requests for more now... :^)

It is looks great on the camera!

Image is fixed now
