How do you spin a bicycle?

Friday, May 7th, 2010

As we all know, internet retailers sell EVERYTHING. Due to this wide variety of shapes and sizes, we need to get creative with how we rig up a product for spin photography. Many items can simply be placed on the turntable, while others need some “propping up”. There are a new set of complications that come into play when you want spin an item instead of just photography it from one angle. Also, since at Snap36 we use a automated system there isn’t time to be readjusting your “rig” for each angle. Another consideration when setting up for a spin is post production. Photoshop is a great tool, but internet retailers just don’t have the budget for you to retouch the wood block out of every file from a 48 image 3D spin.
We use a robot called the Cube that allows us to hang and spin products. This ability to hang odd shaped products with clear monofilament greatly expands our abilities. It also simplifies the hell out of the whole process, from photography to post production. Hanging a bicycle for spin photography is a great example of what I mentioned above. Here are the basic issues with spinning a bicycle; the bicycle needs to stand straight up and it won’t do this on its own, complicated rigging can’t block any part of it during the spin, it’s big and odd shaped, the client has requested a clean white background, outlining a bicycle can take forever x 24, you can’t spend all day spinning one product even though it looks really cool.
A picture is worth a thousand words, right? I’ll still try to explain what you’re seeing and how this setup is so beneficial.

By hanging the bicycle we are eliminating complicated and “heavy” rigging needed to stand it up straight. With the 30lb test clear mono attached correctly, gravity helps us out quite a bit. A few adjustments and our bicycle is hanging straight and level. The white sweep is set back far enough that it is evenly lit and reads almost 100% or 255. With a clean white background and clear line holding suspending the bicycle, retouching is kept to a minimum and manual outlining is not needed. Only where the line crosses in front of certain parts of the bicycle will retouching be needed; these are quick and simple fixes. When spinning products that might have some wobble or shake, we can slow the Cube’s movement down to a crawl. There can be some very small movement, but the short flash duration of the strobes will take care of that. Once everything is set to go, we can photograph a 360° 24 image spinset of a bicycle in under 5 min without having to touch the bicycle during the process. Here are a few finished spins for you to check out.

The “Photo” in Spin Photography

Wednesday, February 10th, 2010

I quickly touched on many points last time; let’s get into technical explanation of what 360° and 3D spin photography is.  A Spinset, you’ll hear that term alot from me, is a set of still images photographed in a certain order and from distinct angels to create a 360° (flat rotation) or 3D (well . . . three dimensional) online visual experience.  To create the final interactive spin, the spinset is fed into spinviewer software or uploaded to a rich media provider where it is compiled into the final seamless spin you see online.  Right now, Flash is king when we’re talking about interactive spinviewers; so, no spinning on your iPhone just yet.  I’ll detail viewers and rich media providers later.  For now, I will try to stick to the photography part of the equation  In particular, I’m talking about spinning products for online retailers, but it could be used to show off any three dimensional object.  Museums and art galleries could use this tech to give a person the ability to experience a sculpture online if they are not able to visit the piece in person.

Anyway, back on track.  You will also hear me reference Rows and Columns quite a bit.  Since computers need some logical order to operate, we need to think like them when we’re capturing the spinsets.  A grid of Rows and Columns is the best way to visually show how all the images are put together.   Anatomy of a Spinset is an example of  a 4 x 16 spinset, 4 rows by 16 columns for a total of  64 images.  Columns are the points around the circle, X axis, where the product is photographed.  Rows are the vertical angles, Y axis, the camera is stopping at as it moves over the top of the product.   In the 1st row of Anatomy of a Spinset, the product was photographed every 22.5° along the X axis with the camera staying put at 0° on the Y axis (If you stopped here, you would have just completed a 360° spinset, 1 x 16).  For the 2nd row, the camera then moved to 30° up along the Y axis while the product repeated the same rotation every 22.5° along the X axis.  Rows 3 and 4 continued in the same order with the camera moving up to 90°, directly overhead.  Since the product is rotating 360°, the camera only needs to move 90° to capture all the views needed.  What about the bottom for a truly mind blowing 360° 3D spin?  The simplest way would be to flip the product over and repeat the whole process.  The images would then be put into the proper order in the viewer software.  This is just one example of how a spinset could be created.  Obviously, there can be any number of variations of Rows and Columns based on a client’s needs or their website’s limitations.

If you hadn’t noticed, we’re talking about a ton of photography.  Any skilled photographer is capable of capturing these images, but it could easily take two full days to capture 64 images of a single product without some help.  To make this viable for online retailers, see economical, a spinset just can’t take up two days of a photographer’s time.  At Snap36 we use the FotoRobot System which allows the quick and repeatable creation of spinsets in a studio production environment.  The images for Anatomy of a Spinset were photographed in less than four minutes. Four minutes vs. two days.

Hopefully, this has helped to explain the basics of  how the images for a spinset are ordered.

Take care,

What is 360° and 3D Photography?

Tuesday, February 9th, 2010
When most people think of 360° photography, real estate virtual walkthroughs or spinning cityscapes come to mind.  3D conjures up images of crazy dual lens cameras and muti-colored glasses.  360° and 3D photography as a sales tool for online retailers and manufacturers is what I’m talking about here.  It involves multiple still images (tiff, jpeg, gif, etc) put into a rich media viewer that allows the user to seamlessly move around the subject to se all angles and details.  As technology has moved forward, faster broadband and more powerful computers have brought rich media features to the forefront of online sales for a multitude of products.  The ability to spin a product around and zoom in just by clicking and dragging with a mouse is changing the online shopping experience for consumers.  This interactive control over the product is giving the consumer an experience which is much closer to the in-store experience.  Take shoes for example; who would buy a shoe without picking it up and looking at it from all sides.  Just standing there and looking at it on the shelf would not be a satisfying way to buy anything.  Spinning lets a person interact with the product and see it from all angles.  Also, with the correct viewer (that is whole other discussion), zooming at any point in the spin experience is possible.  Ok, back to the shoe, you can move it around as if you were holding it and then zoom in on the details just as if you pulled it closer to your face! Or. . . you can look at one static image?  Any three dimensional product can benefit from spinning, and the possibilites are endless; digital camera, clothes, handbags, bicycles, sporting goods, appliances . . .What is the difference between 360° and 3D when we’re talking about online product photography?  Simple, 360° is a flat spin where the product rotates as if on a turntable and the camera holds position, www.snap36.com/sample/bike.  3D spin photography starts the same as 360°, but adds the movement of the camera coming over the top of the product, www.snap36.com/sample/stapler.  This is a lot to digest, but I will go into more detail later, so check back in often.  To see more examples of spin photography, check out our gallery at www.snap36.com.
