E61 Paper Towel Tubes and BFL

E61 Paper Towel Tubes and BFL

November 7, 2020

This week we talk about making your own lenses, why Back Focal Length is meaningless to Ethan, and how to play around with loose achromat lens elements to make your own, homemade lens.

The formula: Formula:

F = (f1 x f2) / (f1 + f2 - d)

BFL = (f2 x (d - f1)) / (d - (f1 + f2))

f1 is the front lens,

f2 is the back lens,

d is the distance between the lenses.

F is the focal length,

BFL is the distance between the back lens and the recording media (film, sensor)

A link to a spreadsheet with the formula in it: https://docs.google.com/spreadsheets/d/1yQ3dsD0Rs-HflRcnPYHSmK0soLXtykGAPl8pdZcrBpM/edit?usp=sharing

Special thanks to Erik Mathy (https://www.instagram.com/erikhmathy/ @erikmathy).

We first heard about this formula on an episode of the Large Format Photography Podcast (https://largeformatphotographypodcast.podbean.com/)

We also talk about a modified Adolescent Crown Graphic Nick's working on.

Ethan mostly tells Graham his formula is wrong.

Graham mostly tells Ethan he names his products after rodents and wonders when the Cameradactyl Chipmonk is coming out.

Graham offers to give away a bunch of darkroom equipment to someone in Northeastern Florida (Jacksonville to Ocala, Daytona to Gainesville). Email Graham@homemadecamera.com if you are interested.

Warning, Graham swears at the very end. If this had been edited by Simon of the LFPP and Classic Lenses, there would have been a gap where you guessed what Graham said but because Graham edited the show, you hear a bunch of F-words in a row.

Finally, we may be taking the month of November off from recording. Don't worry, we'll be back by the Winter Solstice when things are darkest.

E54 John Aldred of DIYPhotography.net

July 21, 2020

In this episode the guys talk to John Aldred of DIYPhotography.net and youtube fame.  John is one of those analog (and not so analog) industry figures that Ethan fealt like he should get to know, but he never expected the breadth and depth of Johns knowledge and stories about venomous snakes.  (Hint: there's a great one after the end music).


John writes about trends, products and techniques in the photo and video industry and about technology in general, and is a rare tech writer who will cover smaller and more niche products.  It's a little bit of a different perspective than our usual camera-building guests, which was a good thing.  John has a deep love of tinkering and it really shows.

E53 Nicks Baby Speed - Our first Video Episode - WATCH ON YOUTUBE

July 20, 2020

In this episode Nick shows Graham and Ethan the camera he has built from a baby speed graphic.  


This is our first episode experimenting with recording video.  The video is low quality webcam footage and screen shares, but we thought it might be a good starting point to show what we are talking to eachother about.  If you are listening on a computer, we recommend watching the episode on Youtube instead.
