Light Source Challenge - DPChallenge Forums

those are all good questions but defining the terms:

a reflector isnt necessarily a mirror

even if it was a mirror or several you would want to set it up in a way that conveyed it was one light source i would think.

all of this discussion comes under the mantle of 'acceptable risk'. if you could pull off one light with reflectors and still have it obvious it's one light and still create a striking impactful photo, im sure many would take their hats off to you.

if there was a doubt, it would prolly lower your score.

the risk is up to the photographer. he or she may lose the money they spent entering the contest :P.

would firing a single strobe multiple times be valid for this challenge??

I think so it's a single light source. i.e. a "source", not necessarily how it is used. As long as you use one light source it's fine. I don't see any restrictions on motion, or number of times you turn it on or off.

Or if you shine 3 light source to the same place the shadow would be gone :) but one it'll show up somewhere. It depends. Soft lights the shadow will dissappear in some situation.

In my opinion tho, this week the shadows will be what makes a winning photo.

So from your statements I can't tell - is the moon valid or not ? :)

Remember - the moon simply reflects light from the sun, which is not "artificial" by the intent of the challenge.

sentence deconstruction:

clearer?

ie. if it ain't the sun or the moon, use it. that's my take.. however im not joe voter ; )

from what i take from the challenge ....
the sun and moon and even fire would all be natural sources of light ...

so dont use them :)

I know that some people think that fire would be artifical - but ultimately it's a natural source of light - you can create it - but so can nature .. so i'd stay away from using fire as your source of light

The moon isnt a light sourse, it's a reflector for the sun :)

I was only lightly teasing, as the moon, simply being a large reflector
would be valid by your second statement, though it is reflecting a non-man-made
light source, so is invalid by the first.

I have a switch in my apartment that turns on or off a 'natural' look
gas fire. Literally it is a light switch that starts/stops the fire.

To me that would be an artifical light source - it is entirely man made.
Certainly as much as a light bulb is 'man-made'

If I set fire to a piece of wood, I'm initiating an exothermic chemical
reaction that gives off light. If I cause electrons to move through
a piece of resistant wire, I'm generating heat which as a by-product
emits light. Both the same ,both artifical, both should be perfectly
valid.

Perhaps a forest fire could in some cases be considered natural,
though often they are set by arsonists too - a man made/ artifical light
source again :)

Isn't this a joy every week ? :)

oh i got it but i would think that a reflector of a natural light source would be 'double questionable' and therefore it's 'forbidden-ness' somewhat more self-evident ... : )

i also like to spell things out so that the non- deep thinkers that read this don't have to infer TOO hard ; ) ...

Natural or artificial? ;)

that would be natural, but you could only have one! :-)

But if it is a jar full of them then its man-made isn't it - how
else would they all get in there ? :)

i'd expect to see teddy bears and flowers :)

I have done my first experiment with 50 shots or so, looks decent. No flowers or teddy bears i am afraid. In fact, I am thinking about making a SIN submission for the next 6 challenges to complete the cycle, making it fit within the restriction of the challenge.

ROTFLOL. Yes, the nitpicking of what the challenge allows or not is just stupendous (And D&L are laughing their heads of.) After kazillion posts some sort of consensus is reached as to what is allowed or not. The sad thing is though that the "doesn't meet challenge" anal voter doesn't seem to read those threads.

This is the first week I didn't submit and it is SO PEACEFUL. Not having to scurry to dpc every hour to look at what might have happened to a lousy score (seeing it joyfully go up by .07 only to have your hopes dashed in the next score update) and to read another in your face comment.
