What do you prefer ? let the viewer explore his imagination or influence him ?

Arches National Park ...

but the park is 310km² big ... does the title help me ?  Huh

Maybe it should be titled "Gateway to Dimension Five and Three Quarters" or maybe '2.09 Degrees' - the angle the horizon appears to be off by.  Grin

I guess that if I photograph a white paper illuminated by the light source, it must be possible from the RGB values to find out the color temperature. Anyone knows how to do that?

Problem: if the white balance is wrong (in camera or in RAW converter), the white color can be just about anything. So how can you know if the color comes from the illumination or the JPEG/TIFF conversion?

The only solution I can think of is shooting RAW and doing color picker white balance adjustment from the white paper. At least Lightroom provides the color temperature when doing this.

I have the Singh Ray Vari ND - and it was terrible for me frankly.  I ruined an entire set of photographs on a 24mm lens at point of the arches.  It's not built for wide angles.  On another note, I have a Vari ND filter for sale, and it's fairly good for longer lenses I hear... I've replaced it with the Tiffen 1.2 Digital HT and I've been happy with the results from this filter.  No color cast, does the job.  I'm currently looking for a 10 stop however, I'll probably go single filter as whenever I stack I seem to run into issues with light reflecting strangely, vignette, or the filter cutting into my field of view on wider lenses.

and forgot nobody buys today used phase back ccd like before...price really dropped.this is already the

For the last five years we've sold more new backs than the year before, more upgrades than the year before, and more pre-owned/refurbished backs than the year before.

I suspect the strong trade-in value that P1 offers for upgrades, and the number of good deals we've had on refurbished backs (that carry warranty and dealer support) has more impact on interest in privately-sold-CCD-backs than does underlying interest therein. In my experience most people like to buy $10k+ cameras from a place they can test it before hand, and where there is warranty/support after the sale; it's not like buying a $500 commodity lens for a Canon.

Some nice shots and interesting regarding the technical challenges of shooting.
But the woffle about how he doesn't like doing things in post followed by the video then explaining his retouching techniques and the 'subtle story behind each picture' was simply artwank nonsense which took away from the images rather than enhance them. The ones with a man in as well were the stronger images in my view.

When you listen to Debussy, La Mer (The Sea in English) do you envision the sea in your mind's eye?  Perhaps you do.  The music is very obviously program music and is very descriptive of the sea, so perhaps you would have made that connection for yourself.  But in this case Claude Debussy took the step of insuring that you understood.  By naming the piece La Mer, Debussy framed the listeners' understanding of the piece far more than if it had been called Symphonic Tone Poem #23.  Perhaps when you name a photograph, you are specifying the lens through which the viewer sees your image.

Not necessarily as bigots have no shame.
If it was the case you would have a clear answer every time.
