    Yes... Sure it is, it's called "expose to the right" or ETTR.  You get enough steps of distinction that you can expand the range of a scene without loss or banding.  If you did a simple +0.3 ...
  • With an SFD shot? Because Ansel was the ultimate tool user.  He dodged and burned like crazy and did other darkroom manipulation to get what he wanted. So one would have to imagine he would ...
  • I thought you had a pretty good list of stuff (although I think if you tried the portrait grip you might not care about the AC adaptor so much). One followup question - how would you trigger the ...
  • I don't think a lens is going to be that much smaller than the DP0, and the great thing about having the DP0 instead is that if you main camera dies on the trip at least you have SOME camera. That' ...
  • How is that not ~50 seconds for three shots, for a total estimate of 140/3 = 47 batches of three, then 47 * 50 = 2350 seconds total, which is 39 minutes total. I don't have the camera in front of ...
  • That was an interesting article, I do not think the quick method works on the Quattro as taking WB from a lightbulb the shots after using the custom WB did not seem to have any kind of color cast, ...
  • Sigma is still making and selling the Quattro H.  Ask your supplier why they are lying to you.
  • The Quattro can produce DNG files so that part is wrong. The Apple iPhone/iPad can produce raw images now if an app desires. Basically a lot of nonsense to what end?
  • Even though this is an article on DPReview, I thought I'd post I link to it as I normally would not have seen it as I go straight to the forum and don't read the rest of the site very often: https: ...
  • First of all, are other camera makers reporting ENOB?  Or would they be similarly downgraded in technical analysis of the sensors? Secondly, why would it matter if the EBOB is less than the number ...
  • Because a linear DNG file has been converted from the three different layers, it could well be that some in-camera settings would also affect the generated DNG file. I may try experimenting with ...
  • And me.  The thing, while some here may disapprove all of the people who already own Sigma lenses approve.  Most other potential buyers would own the "wrong" mount if Sigma went with either Nikon ...
  • I have the newer 70-200, it is really good., very sharp and better than the old version  But more recently ice either been using the 150-600 (which is rather large) or the 50-100 (probably not as ...
  • What attracts you to the camera? More importantly, what do you consider to be "low light" you'd be working with? With the newer firmware, the SQ Quattro focuses pretty well in lower light with my ...
  • Using higher quality compression there is still some loss, although minor and you would not notice it for a number of saves... The major issue I have with shooting JPG only as a starting point, you ...
  • Focus does seem faster (and locks in better) on my 18-35 f/1.8.
  • If you are interested in landscapes the extra resolution of the H would be nice. The lens you are thinking to buy would be usable on either camera, if you are interested in any DC lenses they may ...
  • On the WEX website the Q is listed as "in stock", the H is listed as "special order" - there may be a premium for that. On BHPhoto the Q is listed as $799 USD, the H is $1199.00 (and is in stock).
  • I can't see how it would possibly impact H sales, since DNG support for the Q was announced long ago - other than that all the reasons why you might get an H instead of a Q are all still the same.
  • Don't get mad but... have you tried taking off the lens hood? Not even joking, I tried a 8mm once and didn't realize the front was a lens hood I could remove.  I seem to remember results looking ...
