comment Is this xray fogging on my film? Or something else entirely? (with examples)
@OlinLathrop - well I can clearly see faint blue tinted stripes/blobs.... (but I cant answer the question)

comment How much does a drop in temperature affect focus?
yes... so its basically impossible to calculate without an extremely advanced computer model (which will probably be wrong anyway when you factor in grease/lube, tolerances, wear etc)

comment How does photography (as opposed to physics) define “focal-plane”?
As far as i can gather the "focal plane" is the point behind the lens at which the image is in focus (or at least the part of the image you WANT in focus...) this is of course not always at the sensor / film, therefore i would say no, the sensor/film does not ALWAYS occupy the focal plane. I would say that is therefore the "desired" focal plane.

@MichaelClark - yes 2 reasons: I have no way of calculating that, and secondly there is a huve variation in materials, shape etc of the optical elements.

no, actually i was thinking about the quality of focus of point sources (stars), AA is there to slightly blur the image, so is non AA preferred for astro?

This also makes me start considering AA filter Vs none...

un-edited incorrect edit - it is m/m/k (meters per meter per kelvin), not m/k

comment Why does the sound seem different when taking picture in RAW vs JPEG?
Its certainly not a bug, they all do it! more a "quirk"

@TuTran - great! I vaguely remembered this from when i first noticed it years ago on mine. I have made a proper answer so would appreciate it if you could mark that as correct.

@TuTran - 14 bit is better than 12bit, try swapping to 12 bit and see if it still takes longer. According to this review: imaging-resource.com/PRODS/D300S/D300SA6.HTM it has a dramatic effect on processing time...

@TuTran: Are you in 12 bit or 14bit RAW? - this COULD be it.
