Please consider that these results are "real time"-this is what you can expect to see on set via your picture or signal monitor. Also, specifications are limited to shadows and highlights having visible detail-not crushed or blown out. In addition, the pre-knee, knee, and black gamma characteristics will be optimized for the scene.
Keep in mind that the test scene will contain an even distribution of information throughout the contrast range and the gamma crossover point will alllow for an even distribution of signal information. This gives us 7-71/2 stops of contrast total. With compression circuits such as pre-knee and knee, and expansion circuits like black gamma dealing with the non-linear parts of the curve, an extra 2- 21/2 stops (approx) are injected into the emulsion (~1-11/2 in shadow & ~1 in highlight). With white appearing at 100IRE, clipping occuring at 105-108IRE, pedestal at 2-4IRE, then the linear portion of the curve will safely contain 5 stops of scene contrast. This figure takes into consideration the non-linear regions of the durve. Inspite of 12bit A/D conversion and effective compression/ expansion circuits for the knee and toe, is the contrast range of the f900's emulsion much lower than Sony's claim of 10-11 stops? Even if the block is able to output this much information, it's the output to the recording device which is key. Perfect, simple, and reliable every time. Kind of like taking the emulsion from one camera and duplicating it in another.

If you can accurately measure and record various camera parameters you can then just as easily install these parameters in another camera. Tired of crushed shadows? Try the DSC black-everything else is gray by comparison.įor multi-cam shoots there is no comparison. In particular, the neutral characteristics of the DSC charts allow for reliable carrier leakage elimination resulting in perfect scene reproduction from the blackest black, to the whitest white. I use both the back lit Ambi, and the front lit Camalign for everything from flare compensation, gamma crossover setting, accurate white shading, color matrix (SMPTE, EBU, 709) installation, detail circuit balancing, etc. When critical adjustment of HD cameras are necessary, the DSC product is the only choice. In fact, the DSC product is, in my opinion, the only product on the market with enough built in technology and precision to match the needs of complex digital cameras. DSC's test products allow me to do just that. In order to optimize this emulsion, its imperative that I can examine the performance of these circuits during different "real world" conditions. cameras employ complex digital circuits-a virtual "digital emulsion". DSC Labs has helped me to do just that-shoot after shoot, year after year.
I want to give my clients and myself the best possible results every time.
