Next Sunday, February the 28th, I am conducting a shootout between several cameras, including the P4K, P6K and 12K. (If I can get my hands on one, we will also test the 4.6K G2.)
All cameras will be outfitted with the same EF mount lens, with the MFT cameras using a mechanical adapter (no Speedbooster.) Apertures and camera distance will be adjusted so that out of focus rendition matches between different sensor sizes.
Each camera's rendition will be posted online, blind, with a few different polls so that interested participants can try to identify and/or indicate preference. After collecting enough responses to be statistically meaningful I will share results, and probably share the source files.
My goal is to record a test scene that is representative of conditions in which I use these cameras...i.e. controlled conditions for narrative work...but also challenging enough to give the cameras with superior specs a chance to excel. (I'm not going to put a model in a cave and point out towards the snow, nor am I going to record a black cat in an alley at night.)
I'm posting here looking for suggestions regarding the test scene. In particular, can anyone "recommend" a fabric that is gonna reveal moiré if anything is gonna reveal moiré? (I've been remarkably lucky my whole career, rarely running into the issue.)
Here's what I'm planning so far:
- Tungsten lighting (direct lighting on "still life", upstage lighting on models)
- Two models: Fair skin/blonde and dark skin/dark hair (4 stops contrast on faces?)
- Charts: HR-1 Superchroma, X-Rite Color Checker, Datacolor SpyderCube & SpyderLensCal
- Fabric: Black velvet, White cotton, something rough & finely textured (burlap?), something that will easily produce an interference pattern (b&w checkered flannel? Pinstripes? Looking for suggestions.)
- Pure R, G & B LEDs as "practicals"
- Fruit: Apple, orange, banana, lime
- Bottles: various wine, olive oil, wine glass
- Misc.: Something steel or chrome
- Items with colors that BMD color science has traditionally been considered weak: Ryobi green. Looking for other ideas?
- The entire scene will be shot as a slow pan utilizing a motorized slider.
- Some elements will be on a motorized turntable.
Please chime in if you have suggestions or want more details about the methodology we're going to use. I'm also testing various lenses on this day, and I have limited volunteer help and time with the models, so there is a limit to what I can accomplish, but I will try to accommodate as much as I can.
