What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

What's 617 Camera DIY kit Project?

Twofourths camera DIY Kit 617 is a D.I.Y. camera. As the name suggests, it contains two parts of the four-component camera. You need to follow the steps and assemble the camera before use. The parts are made of wood, acrylic plates and metal. Just install a large format lens and use 120 film to enjoy taking high quality panorama photos.

How to make a high resolution photo with low cost camera?    

In2017, high resolution photo could only be taken by expensive digital camera such as Sony A7R of full frame size sensor 42MP.  
Canon 5Ds~50.6MP,  
Pentax 645Z~51.4MP,
Hasselblad X1D ~50Mp.

Alternative, it can be produced by film scanning tool. But the film size, film ISO and quality of scanner affect the photo resolution. According to professional photographers , a ISO 100 4”x5” film can be scanned to 100 mega pixel, a block of ISO100 135 film into 7 mega pixel and ISO 50 was changed into 16 mega pixel.

How the lens work?

The camera lens is able to condense the real vision into image circle projection . If the focal length / flange focal distance is correct, image display is clear, at the same time, the film put into at accurate position records the image at that moment.

Different lens produce different size of image circle, we need to adopt suitable film for taking photo. Following large format lenses are common in the second hand market. Click this to find further information of numerous large format lens. ~ Large Format Photography. Info

These are some large format lens online market, check out for infomation and prices reference.
www.keh.com,  www.catlabs.infowww.bhphotovideo.com, www.ebay.com  largeformatphotography.info

The green zone lenses are smaller, their image circle is between 100mm and 165mm, so that 4x5 film will cover it.

The blue zone lenses are little bit bigger than green zone's, these image circle is between 170mm and 200mm, so that 5"x7" film cover it

Our Solutions.

Although default film are 4x5 and 5x7, we offer a lowest cost option that also allow convenience on film use and developing. The shortcoming is that top and bottom of image will be reduced to change the object from square to rectangle. About 50% of the image taken will be cropped.

To make up for this, we offer two solutions. First is 617 camera via 120 format as film media, the second is instant camera via Fuji film instax wide , they are popular and easier to find than 5"x7" and 4"x5"film.

<<617 camera DIY kit Solution>> compatible with any 120 format films, As a recording media, the effective size 617 (6cmx17cm) is almost equal to 50% of 5"x7", if we assume 5x7 is a Hotdog. 617 is equivalent to the sausage, tomato and cheese from the hotdog, with the top and bottom of bun wiped off. It is good at taking landscape and panoramic photograph.

<<Instant Solution>> The vintage lenses instant adapter DIY kit is compatible with Fuji instax film wide, the film size seems to be cropped off 38% from inner border of 4"x5"film. But you can get instant photo immediately, at anywhere anytime.



1st. Solution,  617 camera DIY kit

What is Flange Focal Distance? 

Every large format lens carries the distance (“mm”) in it name. it is lenses focal length, made easy classification for lenses type.

Every large format lens also having a flange focal distance announce by the manufacturer, This distance figure is their minimum length of each lens. Keep the lens rear and the film apart according to this distance. The image will be distinct clear. It is great for landscape shooting or any subject standing 12 meters or infinitely far away.

The key to taking excellent photos with our low-priced camera is accurate adjustment of the distance between the film and the lens rear, The wooden board and auxiliary parts ( 0.2mm~10mm ) can be used to adjust the distance between the under 200 mm lens and the film. Lenses mentioned here are some of appropriate large format lenses.

The translucent tracing paper included in the DIY Kit is used to simulate the film and used to help align the position for a clear image. It is important to do it right during the camera assembly. For better result, you can use a magnifying glass to help with the alignment.

1st Solution Plus+
617diy Adjustable focusing Set (optional)

DSLR helps focus at the image

Lengthen this distance and focus on closer images. Based on this rule, you can adjust the shooting range by the additional focus ring between the lens and the film track.

Combines our optional 617diy adjustable focusing set, The camera can be used to shoot at close range (e.g. 3m~12m), such as group photo. Set the focus ring to adjust the focal distance. Use the digital camera to simulate the film and focus at the image, mark the different target distance when the image is clear.

617diy adjustable focussing set is an option, it adjust focal distance and target easily.

 The Rewards:

Risks and challenges

The twofourths 617 camera DIY Kit project kicked off in Spring 2015. From design, production, testing, product improvement to final product creation, I attended to even the smallest details in the project. The only challenge we face is the production of six different 617 adjustable focusing sets. Due to lack of capital, these adjustable focusing set prototypes were not produced, once we received capital from Kickstarter. We will produce these six prototypes, fix them on the lenses, test, improve and produce them. Since we are experienced in metallic items manufacturing, we believe we will be able to meet our clients' need within the timeframe.
