Build a Back-Lit Slope Backdrop For Better Product Photography

The following article is a guest post by Ilya Titov, a photographer and web designer, who also runs a great blog at blog.webboggles.com.

Are you a photographer who needs to take dozens of high quality photographs every day?

Are you a designer who has to process the above? - I am both, and I cheated.

Well, not really, I just optimized the way I go about achieving the target outcome. I dothis by using a home grown illuminated light table (or slope). Read on for full details.

I work for The Golden Boot and part of my job is to get all the stock online as quick as possible. And it has to look good.

Before I got the Slope backdrop working, it was taking me good 2-3 days to photograph and process a delivery of products. My setup looked like this:

Don't work like this!

I was spending a lot of time tweaking the lighting in the tent, and even more time processing to remove the shadows. Getting new season's collection online was a painful and lengthy process.

After completing the second season I was challenged by my employer to speed up the whole photography aspect of managing the online store.

After a 2 months holiday I came back with a great idea and this AutoCAD drawing:

I figured that the light was the most important influence on quality and that if I could eliminate the shadow at photography stage, it would speed things up considerably.

Product photography tent proved pretty useless in the past so I though "Why not make the background brighter than the foreground?"

The sloped shape was pretty obvious.

I shared the idea with my employer and he agreed to build it. Most of the stuff we used was lying around the shop.

We got a large sheet of opaque plexiglass to fit in the carcass we've built. We had the electrician wire an array of 16 daylight tubes and 4 switches.

It was a very special feeling to see the whole thing work.

Going through Autumn-Winter 2009 stock, I appreciate how easy it is to photograph items with fur elements. They are a nightmare to isolate from the background and will never look as neat.

Here is how fur looks over this slope:

And here is a Manas Heston Boot:

This backdrop is very handy for fluffy items. And it almost eliminates any processing required. It comes down to increasing the contrast and exposure slightly to bleach the background when importing from raw.

Another bonus is that there is little to non lens flare to deal with. (The images in this post were taken with an EOS400D and an EF-S18-55mm lens)

What was the final wattage

What was the final wattage used to power the whole system? Love the setup, I may build one for myself too in the near future.

Power consumption

Not sure about power consumpton, I would guess it is between 500-1000 watts/hour

Coolness

Interesting setup. I am doing glass photography from time to time and also work with a tent what stays on plexiglass. My lightning is done by two 430EX2. Each glass (beer, champagne..) needs a slightly different lightning and it's a pain to find it and do the final cuts using curves in PS.

Neat Idea

This is a great idea, and it looks very well built to boot (ba da pum!).

Great idea! Why didn´t i

Great idea! Why didn´t i have it??? Good post!

Put a model there

Wow if you build one big enough you could put a model on top of it.

You could

Also it would be tricky to make the floor strong enough.

Probably possible if you put some sort of translucent support grid under the floor part.

I am curious as to why the

I am curious as to why the floor is not level/parallel with the bottom, but goes up at an angle, while the back wall is straight up and down, parallel to the frame. or is your cad drawing rotated 90 degrees? Great setup, great idea, great execution! Thanks for sharing!

yes it is

The floor is straight and the back side was intended to be at an angle.
Although both sides were built at a right angle later on.

great idea. looking into

great idea. looking into building one for myself. im looking at using some cfls but they wouldn't cover as much area as the tubes your using.. if you were to turn every second light off, is there a difference, ie: dark spots? my thinking is the plexiglass should distribute the light quite evenly though this might be dependent on the distance of the lights from the glass. if you could like take out every second tube and try it, ill be extremely grateful for the feedback. maybe even try with 1 in every 3, only being on. thanks again for the great post.

there is no dark spots

There is no dark spots when you turn every odd light off.
Also I can only turn off every other light, allowing only half and full power.

The plexiglass ensures an even spread, but the lights have to be quite far from the surface. If you are building a small backdrop using cfls, you could use polarising sheets from an lcd screen. They are very good in distributing the light from a single tube.

might try to add a turntable

we use a full white background on most of our photos, we shoot 360 product shots. After reading this post, i think I will bodge together a similar version, but have a double layer of plexi on the bottom to have the ability to use one of our turntables in it. I had tried something similar in the past, but after reading this I gotta try again.

360 product views

novice

hi i am a novice and have an online store -luv the concept to shoot items-could you hlep me with more specific information
-1)the white background you used,what material is it ?
2)how many watt daylght tube did u use?
3)i see u used free standing lamps-how many wat globes were those?
