Black-crowned Night Heron (Nycticorax nycticorax) by alabang, on Flickr

The Black-crowned Night Heron (Nycticorax nycticorax), commonly abbreviated to just Night Heron in Eurasia, is a medium-sized heron found throughout a large part of the world, except in the coldest regions and Australasia (where it is replaced by the closely related Rufous Night Heron, with which it has hybridized in the area of contact).

Just to carry on the Xmas theme, Munchie our pet rabbit waiting in anticipation of Xmas day....

... about 10-seconds before he decided eating the wire to the lights was a better idea  :(


That almost looks like a Christmas tree on his back. :)

Thanks RienzPhoto, rpt, Click and Dylan777.

December seems to always be one of the best month's for sunsets in the San Diego area.  This one was taken five minutes down the Silver Strand from where I work.  The Arleigh Burke destroyer anchored finally making it possible to do a long exposure.  10" : f/14 : ISO 100 : 5D MK III : Canon 24-70 V1 @ 70mm



Superb colors


+1...What an absolutely gorgeous photo. I just love those colors. Magnificent!

Thanks guys: Afraid to say its a captive Eagle. I have a bird of prey center near me that offers some excellent photo ops both like this and in flight / hunting. I have some more if you want to see them?
It does not matter if it is a captive eagle or not.... that is a great picture!

I don't think I would join any club that didn't want me for a member ;D

PS- Lots of places define professional as getting any payment (even once and for any amount) for your work. Recently, a US college basketball player had to forego a monetary prize ( I think it was $20,000) for a half court shooting contest that he won, because, if he accepted the prize money, it made him a "professional" basketball player and thus ineligible to continue to receive his college scholarship.

Canon EF Prime Lenses / Re: Canon EF 100mm f/2.8L Macro IS USM

Common Brown butterfly. Resting on the side of my house, waiting to warm up in the coolness of the morning.



After a few minutes, it started to slowly pump its wings, as the sun started to shine. A minute or so after this pic, it took off. Probably didn't help having a macro lens 200mm away, flash popping off :)


Wow! Lovely and great detail.

I have the same problem on my macbook pro using safari. This all started several weeks ago. Until then, I never noticed this. Something has changed with the site.

Technical Support / Re: Best Possible IQ

For the life of me I cant figure out why so many of you are saying there will not be an IQ difference on a coffee table book if shot on a 35mm 23mp camera vs a larger 60mp sensor....

Must get to the bottom of this!

Join the circle of confusion :)

It's really about the output.  The best quality commercial offset printing is done via halftone screening at ~200 lines per inch (LPI) - that's for art books, as opposed to magazines and newsprint which use lower resolution screens (in the 80-150 LPI range).  Printers generally want twice that in dots per inch (DPI) of digital resolution. 

Most coffee table books that I have and have seen are square.  That means a 2-page spread will have an aspect ratio between 2:1 and 2.4:1 (allowing a 1" border with no gutter, bigger books get closer to 2:1).   To cover that aspect ratio, you'd need a 4-frame stitch from your 3:2 sensor in portrait orientation (~3.3 frames needed, but you always need overlap to stitch).   With the 22 MP of the 5DIII, that gives you ~70 MP final image.  A 2-page spread of a 12x12" coffee table book means a 22x10" image, so at 400 dpi you need  8800x4000 pixels, or 35 MP…you'd have twice the amount of resolution you need.  That 70 MP image would be sufficient for a 2-page spread in a coffee table book of up to about 16x16". 

If you need to go larger, you can use a longer focal length and stitch a two-row pano together, although that gets a little more complicated (you need a multirow pano setup, rather than just a single-row).  You can put a 1.x4III behind your TS-E 24L II, and still have excellent resolution and IQ from the combo.

Neuro...as always, a clear and succinct explanation of the problem. Thank you for posting. We all learn so much from you on this site. 8)
