For quick shoots, any digital camera will do, including cellphone cameras. But for a controlled shoot, I recommend:

– 50mm lens
– Tripod (depending on conditions)
– Remote shutter release (if using tripod)
– Strong, diffuse lighting
– Polarizing filter (for shiny objects)
– Measuring tape
– Blue masking tape


Strong, very diffuse light is best. Harsh shadows can create problems.

A motionless, non-reflective, and varied background is good. The more random features there are in the background, the better the system can track points and triangulate.

A monochrome, uniform, featureless background can be problematic. Add clutter or tape marks to the background.

Repeating patterns on carpet or wallpaper are problematic.


Light-colored, matte materials with some color variation are best. Dull, weathered stone is ideal.

Shiny, reflective surfaces are problematic. A polarizing filter may help reduce specularity in some cases. Dark, shiny bronze statues are very challenging.


Use as low an ISO setting as possible, to reduce noise. The software actually matches pixels to pixels from one photo to the next, so sensor noise creates a lot of problems.

Use as small an aperture as possible (high F-stop). The foreground and background both need to be in focus.

Use a tripod and remote shutter release for longer exposures.

If using a high F-stop is not possible, and the background cannot be kept in focus, at least try to keep the subject itself entirely in focus. Filling the frame with the subject can also improve results if a lower F-stop must be used.


Take a measurement of a linear feature of the subject, or something in the background that will also be picked up in every shot. If feasible, place an object with a straight edge and known size in the scene, near or against the subject, and leave it there for the duration of the shoot. Don’t move it during the shoot. These will provide scale references.

Before shooting, find a distance from and path around the subject and a single zoom length that will allow you to take all your photos without adjusting the zoom. Avoid getting so close that you see big lensing/fish-eye or perspective and foreshortening distortions.

When shooting, don’t change the zoom ring at all. This is critical—you can move the entire camera closer or further away from the subject as needed, but don’t change the lens or exposure settings at all from shot to shot, as doing so will ruin the survey.

Try to have the subject fill the frame as much as possible.

Rotating the camera from shot to shot—from portrait to landscape or anything in between—is OK.

The light source cannot change or move relative to the subject at all from shot to shot. Don’t use a mobile flash. Any light source or flash needs to be fixed relative to the subject.

Take at least three laps around the subject, shooting from medium, high, then low angles, keeping the entire subject in frame. Then for additional close-up detail shots, take additional laps around the subject while aiming the camera so that the lens’ line of sight is perpendicular to the surface of the subject in the frame.

Take all photos in sequence—each shot should overlap with its neighboring shots. Don’t jump around the subject.

Every point on the subject must be in at least one series of at least three consecutive shots. The more series, from multiple angles, and the more consecutive shots per feature, the better the system can match points.

Make sure to take photos of features that are obscured by other features.

If you want to try different exposure settings, treat each shoot as a completely new photoshoot. Never mix settings between complete shoots. Take a photo of something between settings changes so that later you can see at a glance where the different exposure sets start and stop.


Don’t edit the photos in any way. No cropping, re-sizing, levels adjusting, or masking.

When uploading, start with the shots that loop around the subject while keeping the subject completely in frame. Low, medium, and high angles. Then add any detail shots.


If practical, shoot in RAW, in addition to JPG. Some applications may be able to get better results with different JPG compressions of the original RAW files.

Shoot more photos than current software requires. You may get better results from set-to-set, or from different loops around the object within a set. More powerful applications may soon be able to get better results with more shots, so you may as well take as many as practical instead of going back and starting over a year later when more powerful software is available.



My client asked for a life-sized 3D printed portrait of his colleague, venture capitalist Brad Feld. Because the portrait was to be a surprise gift to Feld, there was no opportunity to scan the subject. The piece had to be modeled from photos of him culled from the web.

I proposed a bust, roughly from the shoulders up, with classical allusions, but I was vague about the details beyond that. The final design references the Artemision Bronze, Leighton’s An Athlete Wrestling with a Python and a few other sources.

I took a risk and bet that they’d like something other than a standard chairman-of-the-board type treatment. And what’s the point of having rock & roll hair if you aren’t going to do the whole heroic barbarian-warrior-champion-god thing when you have your life-size 3D printed portrait done?

This is the result.

This kind of remixing is just one small reason the world’s back catalog of public domain sculptural artwork should be digitized and published, freely, and without restriction.

I’m tinkering with ideas and images for possible presentation at LACMA. This is a comparison of people’s response to the original Venus de Milo in the Louvre to their response to my 3D captured, 3D printed copy at the 2013 Paris 3D Printshow. The show was in the Louvre expo space, so my print was just a couple hundred feet away from the original.

I’m thinking that the fact that so many people are viewing the original through screens and taking photos undercuts the argument that there’s some essential, ineffable, supernatural awe involved in seeing the original, when really what people want is interaction, touch, control, and possession, all of which they get by mediating their experience with cell phones and cameras (for now).

I’m working on ideas and images for a possible upcoming presentation to LACMA staff on 3D printing, 3D scanning, art, and museums. Here are photos of people at last week’s 3D Printshow in Paris responding to my 3D printed invention of Perikles’ helmet—a copy of an artifact that hasn’t been discovered and likely does not exist. Photos and touching allowed…

Because when’s the next time I’m going to be alone, after hours at the Louvre, with Vangelisesque muzak playing on the PA system, with my 3D captured, 3D printed bronze-cast bootleg of a Matisse? I found a buyer too…

In response to Thingiverse’s “Capture Your Town” challenge I’ve captured several locations in Anaheim; “my town”, broadly speaking, being Southern California. These are significant locations here, for horrible reasons:

The first 3D photoscan is of an ephemeral memorial marking the location where Manuel Diaz was shot to death by Anaheim police on July 21, 2012, at 704 North Anna Drive.

I spent several hours scanning sculptures at the Norton Simon Museum in Los Angeles in June 2012. I was very happy that their 1905 cast of Auguste Rodin’s 1877 The Walking Man scanned the best: a seminal piece from a movement dedicated to seeing and expressing the world in new ways, with new eyes…

When The Getty Center first opened its doors in 1997, a local billionaire remarked that it was “too good for Los Angeles.” Luckily, the J. Paul Getty Museum knows better. Nothing is too good for Los Angeles, and no works of art are too good for the people who admire them.

For thousands of years, powerful people have commissioned artists to venture into museums, churches, temples, and ruins around the world to make copies for their private collections. Today, with 3D scanning, photo-stitching, and printing, that tradition is poised to evolve and spread faithful reproductions of treasured artwork far beyond the walls of elite palaces.

First run of my MakerBot Replicator, printing a default test object: the spiral box. I took this opportunity to explore the elements of the perfect YouTube video: an unnecessarily long 30-second intro before the action starts, cameras that are both shaky and blurry, and an overwrought electronica soundtrack. When I have a bit more time I’ll plaster it with comment overlays. Enjoy!

This was my submission to one of Andrew Sullivan’s View From Your Window Contests:

The view is of buildings overlooking Puerto Vallarta’s Malecon. It’s of a special spot too; a pivotal location in a great movie that helped put Vallarta on the map and gave it a place in Hollywood romance lore.

Whenever I hear the opening minute of Loretta Lynn and Jack White’s duet Portland Oregon, I think that’s surf music. I had to set some Southern California beach imagery to it.

I shot these photos at San Onofre, because what day at the beach is complete without attack helicopter fly-bys and a nuclear reactor?

I really like the Gap ad with Juliette Lewis and Daft Punk. There’s something very genuine about Lewis’ performance, movements, and expressions—it seems like she was having fun making the ad, and it comes through. Watching the Beyoncé video Single Ladies, with its trio of dancers and simple backdrop, it struck me that these two videos need mashing.

These are photographs I took of private homes over a decade or so, with a focus on the windows and doors. Most of these shoots were fairly impromptu, with little notice, scouting, or set up time. All but a few—including daylight interior shots—using only available light. Quick and dirty shots to include in printed and online product advertising.

Every week Andrew Sullivan posts a photo and holds a contest to see who can locate the window from which it was taken; the “View From Your Window” contest.

This video was my entry for the January 7, 2012 contest. My guess was Budapest, Hungary.

I made this video of my search process just for fun, and to cut through all the submissions he gets, but I added the Blade Runner dialog, the stupid computer sounds, and the mind-numbing electronica on principle. (Remember when computers used to make loud clicking and beeping sounds as they were working? Me neither. At least they’re still noisy in the future.)

For some reason, Sullivan—one of the most widely read writers on the internet— never credits the readers who send him the comments or contest submissions he publishes. I took care of that by changing the title of my video after he’d embedded it on his site. See the result here.



This video shows my process from my original photograph of the Vatican museum’s bust of Claudius, through photo editing, to layout in pencil, and painting in acrylic on canvas (36″ x 48″). The recital of Robert Graves’ “The Sibyl’s Prophecy” is from I, Claudius, BBC, 1976.



Virginia [Virginia Postrel, DeepGlamour Editor-in-chief—CW] recently tweeted and posted on Facebook asking, “What photos should absolutely be in a book on glamour?” While putting together this collection of recommendations from pop-culture, I sought out the two photos above, of Sean Young in Blade Runner and Sharon Stone in Basic Instinct.

But it wasn’t until I saw them side by side that I realized how similar they are. Not only do both women know how to hold the hell out of a cigarette, but the images’ contexts are nearly identical.

This is a mashup of the clever interactive Facebook site Take This Lollipop.

Instead of watching the stalker track you down, in my version we watch him experience the full range of emotions that typically accompany first exposure to dubstep: wonder, rage, intrigue, confusion, and, finally, bloodlust.
