18% grey means 18% reflectance, which means 100 footcandles falling on an 18% grey card will produce 18 footlamberts. Vision is logarithmic, meaning it's not the absolute difference between...

Hi David or whoever might be able to help.

Another diopter question.

Lately I've come up against several situations where I want to calculate what diopter strength I need to get the certain...

Dear David, and whoever else may be able to help,

I am shooting some Macro of flowing paint on a phantom for which we'll be using ultra primes and diopters.

I have a choice of 138mm set, 4.5”...

Dear David, I was hoping you could help me clarify the distinction between softness and specularity of a source.

My understanding is that softness is related to the size of the source as seen at...

Hi guys, I am running Cinema Tools 4.5.1 and it won't recognise R3Ds as clips. It just won't import them when creating a database. Does anybody know why that might be?

Looking into the Cinema Tools method now, but Cinema Tools (I have 4.5.1 which I gather is the latest stable release) says 0 clips are imported when creating my database. Seems not to recognise R3Ds.

Hi guys. I need to grade a RED project in Color. FCP project edited with prores. Reconform procedure described in white paper doesn't work as "Batch Capture" opens Log & Capture instead of Log &...

I am obviously no authority on the subject so I'm ready to be corrected, but I would put to you that the sensor sees no difference between less footlambert on an open stop and more footlambert on a...

Sorry, of course they are, I meant 'Any equally affordable alternatives?'. Thanks for the answer!

Sorry to ask another question right after David, hope you don't mind. I know you use Source 4s a lot to put a highlight in the frame, but I am looking to have a well defined tungsten beam in a hazed...

Thanks!

Hi David, I was wondering what you and anyone else reading this thought the most efficient bounce material was out of cheaply available cloths - muslin, silk etc? I know ultrabounce is probably the...

I've used the 80C and the loss is 1 stop, but never the 80C hot mirror. Would the hot mirror component really not lose any light, making the 80C HM equal in stop loss to the 80C?

I recently ran into a bit of flicker trouble shooting under Arri HMI Fresnels with normal flicker-free ballasts at 240fps with the epic.

I know there are special high speed ballasts. I was...

Absolutely - that's why I thought this was used so well in ADM. There is no other way of doing a shot in depth that plays as a long 2-shot without telling the audience what to look at.

I think...

Thanks for your generous reply, David.

Hi David, I know you've done work with tilt-shift lenses to keep both characters sharp in shots in depth, so just wanted to bring your attention to my post about A Dangerous Method to see whether you...

Big fan of Peter Suschitzky's work with tilt shift lenses on A Dangerous Method to keep both characters sharp in shots in depth. The most obvious example is during the psychoanalysis scenes where...

An out of focus shot is essentially a low-passed image where spatial frequencies beyond a certain point (which point depends on the degree of softness, the extent to which the shot was 'buzzed') are...

Egg crates are not for diffusing sources. They are designed to reduce sideways spill from soft sources, thereby making them more directional.

Many have done this before, but here is my personal experience lighting with candles for Red MX.

Hi David. The other day I was interested in mentally separating the range of spot readings obtained at the lens into what is due to reflectance variation and what is due to incident light variation....

I know David Mullen used the epic with Bomb EVF on "Big Sur".. wonder if he had this problem?

I think Mark Allen has hit it right on the head. I feel like we have an easy ride compared to all the cats who deserve as much credit as us and get much less. Everyone knows who Storaro is, yet most...

Just wanted to pipe in in Conrad's defence - anyone who knows the London rental market knows that his rates are only a little cheaper than expected if you figure out the differences in kit between...
