I'm trying to do this as a favor for a friend and am not satisfied with the results. Not sure where to go from here so I am looking for some ideas. I will list some specific issues I have below and any ideas I may have on how to handle them. All comments are welcome, related to the issues listed below or otherwise.

Setup info:
-ISO 1600, f8, 1/250, 32mm focal length on crop camera, custom wb set using Photovision calibration target
-430exII camera right with shoot through umbrella at 1/2 power
-580ex at camera left bare shooting more or less straight up at ~35' tall ceiling at full power
-Setup shot included, lights not shown in final location, I just put it in there so you could see the surroundings

Issues:

  • Camera left side of product has no definition from background. I have no ideas on how to address this. Drop key power a bit? Seems like that may worsen the next issue.
  • The white seamless has color cast (mainly at bottom) and is not pure white. SOOC it shows about 95% in LR at top of frame and about 91% at bottom. Is it reasonable to try for 100% SOOC or will I need to push it a bit in post to get to pure white? Increasing the overall exposure seems to make my first issue worse.
  • I would like more definition between the front face and the camera right face of the cabinet. I am going to try a large black flag camera right and/or feathering my key towards camera left to accomplish this.
  • In general, the photo doesn't seem to pop. Getting really carried away with the basic tab in LR4 seems to help but it is still lacking. Not sure whether this should be addressed at the time of capture or during post. Or if maybe this is just how the cookie crumbles with a light grey product on a white background? What other type of background could be used here? It is a medical product so it seemed to me that white was the obvious choice.
  • I would really like to be below ISO 1600. I need a decent DOF to keep everything sharp so imo I have little to no room to move on aperture. Do I just not have enough power for such a big product??
  • There is a gradient I added in post at the top of the frame that is a little too obvious. Just need to tone that down a bit so try to ignore it for now...

I just did some large white product similar to these. I've had issues with white backgrounds blending with the product so I chose to shoot on a black background and floor. I didn't hit the background with any intentional light. My light setup was actually not too different from yours. I had a 430EX camer left shooting through a 4x6 diffuser about 3/4 power and another camera right just higher through a white umbrella on low power to balance it out. I removed the background in photoshop and added a bit of shadow without too much emphasis on realism but still looked good. Client was happy and I didn't have to struggle with the white product on white background.

To me it looks like your background is way hot and the product is a bit under but I'm not going to claim to be very pro at product shots, I've done about 15. Let me see if I can get some images off my phone and on here and you can be the judge.

Thanks a ton for the reply, this is really helpful. It is great to see someone tackle essentially the same project with such a different approach.

I agree, my background is really hot. I was trying to get it to 100% RGB like yours is and it still isn't there. Photoshop was something I was trying to avoid but maybe that isn't a realistic goal with a product this tone on a pure white background?

It is possible to get it right in the camera. We used to shoot that sort of stuff on 8" X 10" film.* Then the client would spend an extra $1,000 to tweak it to suit his preferences.
But WHY would you want to restrict yourself like that except as an exercise in lighting? ;)
If you need to touch up in PS, then "Life is Good!", & be thankful that we/you have that great option!

*Edit: But when we did it, we used 750 & 2,000 watt lights, so it was much easier to control & see what we were going to get.

This is a very repetitive project (wants his whole product line shot) that would be a breeze in LR with the right custom preset. Adding PS to the workflow is going to increase the post effort exponentially. Not to mention what it does to the file size if you want something you can revisit later. No doubt PS is a fantastic tool to have available to us but I personally try to only make use of it when absolutely needed. And it seems that is less and less often with each release of LR.

Thanks for the post!

My first suggestion would be to rent some studio strobes. This is not really a two speedlite task. To get white backdrops you need to light is separately from the product. You dont really want to be shooting product work as ISO 1600.
