Here's how I came to be interested in these images in case it's of any interest...
About a year ago I got a job shooting sandwiches for a national chain restaurant. THe layouts that were sent to me included some previous work and it showed a soft reflection under the sandwich on white. Very clean and minimal. I asked if this was shot on white plexi and was told yes, that it was...and that all seemed to make sense.
I ordered a few different types of 4X4 white plexi to be delivered to the job some with a more glossy surface than others.
THe morning of the shoot, I was met with a jr. art director from the agency...seems the sr art director I'd been talking to was going to miss the first day but would be there the second.
I set up and started lighting with a 'stand-in' sandwich while the food stylist got to work building the hero. While I was doing that, I glanced over at the jr. art director who was working on her laptop. I noticed a photograph of another sandwich that she was working on and also noticed that it had a much harder reflection than white plexi would produce. I mentioned this to her and she told me ''not to worry'', that they'd done that in post.
Off we go, shooting 3 or 4 sandwiches that day all with a nice soft reflection produced from the white plexi.
On the drive home, my cell phone rang and it was the original SR art director shouting in my ear 'What are you doing? I can't work with those soft reflections...I need a hard reflection". I reminded him of the images that he'd sent me showing the softer reflection and he said that he'd started out with a hard reflection and feathered it back to get that look and that the images I had produced that day would't work. THe jr art director's words came rushing back to me but I know it wouldn't do any good to try and diffuse the situation by telling him as I could tell he was angry and it would most likely come off as a lame excuse. I offered that for the second day I'd bring a mirror that I happen to have at the studio and that we'd make it work somehow considering time was short and it was after hours with no chance to order a front surface mirror like I knew I really needed.
I stopped at the studio the next morning on the way to the location and picked up the mirror...and for the next few hours worked out what was a nice hard single reflection. Initially, I was getting the double image like you, as I suspected I would. At the end of the day, I felt like I'd pulled a rabbit out of my hat to get the job done. In addition to me and 2 assistants, there was the food stylist, the executive chef from the chain, marketing people who'd flown in for the shoot not to mention 3 or 4 people from the agency. I was feeling pretty good that we'd pulled it off especially so considering the wrong direction we'd gotten initially and also considering the ''not to worry''comment.
When it was all said and done, the images were used for billboards and in-store use and as far as I was concerned, successfully. Despite many attempts though, the agency never took my calls again and that was the last job I've done with them.
Just goes to show...???
)THis time I'm prepared. It'll be interesting to see how the dynamics of this job play out. I've shot for this client for 10 years and my only experience with the ad agency is the one noted above. Better be on my best behavior with great surface reflections
