Do It Yourself

Sometimes, the best products are the ones you make yourself. PetaPixel is your guide to custom lenses, handmade camera rigs, custom-coded artificial intelligence cameras, and the 3D-printed parts that makes photography truly personal.

YouTuber Crams a Camera Inside of a Walnut

YouTube creator and do-it-yourself enthusiast Penguin DIY recently built a secret camera hidden inside a walnut shell, and it's an excellent, albeit nutty, example of what creative people with engineering skills can do with miniaturized camera technology.

This Photographer Built an Awesome Medium-Format Rangefinder, and So Can You

Photographer Albert Cornelissen wanted a medium-format rangefinder camera that could utilize great glass and wouldn't break the bank. The second restriction meant the legendary Mamiya 7 and Fujifilm GF670 cameras were out of the question, so Cornelissen took matters into his own hands and built his dream camera: The MRF2.

Photographer Builds 3,200MP Camera Using CCD Scanner Sensor

German computer engineer and builder Yannick Richter, who goes by Gigawipf online, built a new 3,200-megapixel 3D-printed medium-format camera that relies on a linear CCD scanner. As Gigawipf describes it, the camera, Project Gigapixel, is much more than just a scanner in a box, though.

How to Build a ‘Simple’ Focus Stacking System

Each year, my photographic instrumentation students build very simple focus stacking systems. After several years, I decided to construct a more advanced version that could move a stepper-motor-driven stage to precise positions, automatically collect a series of images, and then manually use a stacking program for combination into a single high-depth-of-field image.

This Awesome DIY Digital Camera Has a Waist-Level Viewfinder

Photographer Malcolm Wilson, who recently converted a broken film camera into an infrared digital point-and-shoot, is back with another awesome camera build. This time, Wilson combined a Mamiya C220 TLR viewfinder, Raspberry Pi, and Sony image sensor to create a waist-level viewfinder digital camera.

Can You Develop Film In a Jägerbomb?

Analog photographers love trying new and unusual things. Whether it's shooting on expired film, skipping film altogether, or developing film using odd ingredients. Sweet Lou Photography opted for this last type of experimenting and developed his film inside a Jägerbomb. Did it work?

Lens Fungus: What It Is and How to Deal With It

Pick up a dusty old lens from a flea market, an estate sale, or even your own forgotten storage bin, and you might notice something strange glinting beneath the surface of the front element: delicate white threads, odd patterns like spiderwebs or frost creeping across the inside of the glass. That eerie substance is lens fungus -- an unwelcome guest in the world of photography that quietly invades optical systems, thrives in darkness and moisture, and, if left untreated, can cause permanent and costly damage to your equipment.

The (Lens) Doctor is In: Servicing Your Own Glass

As I’ve collected more and more camera equipment, especially vintage film gear, I’ve amassed a collection of quite a few lenses that I found for peanuts at flea markets, thrift, and antique stores, or online through marketplaces like eBay.

You Can Create an Affordable and Wacky Portrait Prime Using Vintage Projector Lenses

Many photographers over the years have toyed with adapting old cinema projector lenses to their modern cameras. Projector lenses encourage creative experimentation because they are plentiful online, relatively cheap (some can be found for around $50 and sometimes even less), and produce interesting images full of character. James Warner, who goes by Snappiness, created a new video explaining how photographers can create their own "amazing portrait lens" using projector lenses.

Photographer Gives Camp Snap ‘Kids’ Camera a 3D-Printed Upgrade

Photographer James Warner recently created a clever $10 do-it-yourself waist-level viewfinder that works with any camera. Now the builder, who goes by Snappiness on YouTube, is back with another fantastic project, this time turning a digital camera made for kids into a twin-lens reflex-style creation.

Designing a Star Tracker for Astronaut Don Pettit to Use on the ISS

In the spring of 2023, I received a phone call from Peter Blackberg (an old friend, RIT alumnus, and a space enthusiast) when he asked if I would join a call with NASA astronaut Don Pettit. Don wanted to build a star tracker for his next space flight.

How to Use an Arduino to Trigger a Flash With Sound

The high-speed class at Rochester Institute of Technology learns Arduino programming and some simple circuits as an introduction on triggering high-speed flashes in complicated situations. One of the easiest high-speed events to study is a balloon popping. This simple event is also one of the safest high-speed events too.

Awesome 3D-Printed Accessories for Upgrading Your GoPro Camera

3D printers open up entire new vistas of creativity for photographers. Whether you’re into cosplay and creating costumes and props for your portraits or looking to achieve original shots using intricate rigging and mounting setups that are entirely bespoke to your use case, the ability to take a spool of plastic fiber and turn it into a complex and durable part using an appliance that can fit on a benchtop is, in my opinion, one of the most exciting advancements in the at-home maker movement in years.

Venerable Game Boy Camera Reborn As a Fun Lo-Fi Webcam

Of all the low-resolution digital cameras from the 1990s, none has had the lasting cultural impact of the monochromatic, 0.014-megapixel Nintendo Game Boy Camera. Romanian video game technology company, Epilogue, has turned the Game Boy Camera into a webcam, offering nostalgia-infused fun for teleconferences.

This $24 Tool Can Transform Your Leica M Digital Camera Experience

Alongside great image and build quality, one of the most compelling aspects of using a Leica M digital camera is their access to such a diverse library of amazing lenses. However, some of these lenses, vintage and modern alike, lack electronic communication with the camera, leading to photographers manually tracking important metadata like lens selection and focal length. Henley Bailey of Akara Labs has a clever and affordable solution to this problem.
