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!

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)

I may go ahead with 5d3 on this one, but I have made a promise to myself that I am going to test out the medium formats personally in the near future and judge for myself.

I wanted to buy a printer, paper, and a DSLR camera from Adorama to get the Rebate deal from Canon.

The bill came to 1030.

I get an email saying they can't send out the camera because my card didn't go through

They send out the printer and paper without contacting me about the above issue

I don't want the printer and paper because in order to get the 400 dollar rebate, I need a printer, paper, and camera all on the same order. (This should have been a flag, let's get the customer on the phone so we can make him happy)

My card should have had no problem paying for all of it.

Why is there a 1400 dollar charge?

I cancelled my order and had the packages rerouted back to them.

I was charged 97 dollars in shipping because of the way this was handled.

Let me know if you have further questions.

When I'm about to make a large CC purchase, especially online, I call my CC company first and alert them to what I am about to do so they will not suspect fraud. Never had a problem when I did that first.

Dome of the Rock - love the fact that the photographer I captured is shooting the opposite direction.




Gorgeous shot...I love it. Well done.

Awesome. Well done.

And one of the few items (I know, it's not Photographic) but is a bigger lesson in Futility is.....
;D ;D ;D
I bet most of us have at least one Rubik's cube, hoping to crack it one day ... I probably bought at least 7 or 8 of them int he past 30 or more years ... but still haven't cracked it ... 10 seconds and I just give up. ;D

Many years ago shortly after they became popular, I got my 4 year old son, who I thought was a prodigy, a Rubik's cube for his birthday. After all the adults failed, I showed him how to work it and told him the goal was to make each side one color. He went to his room and came back 5 minutes later with it solved. We were all in disbelief. So I mixed it up again and gave it to him a second time. He comes back 5 minutes later with it solved again. Unbelievable. I asked him how he did it and he shows me that each of the colored squares was a stick on piece of paper which he meticulously pealed off and perfectly reapplied until the puzzle was solved. I guess there are several ways to skin a cat. ;D

Great shots everyone!

Here's one of my first attempts at birds. This little fellow (parus major) stopped by this morning.

Canon 7D, 70-200 2.8 MK II with a Kenko 1.4 extender, f4 1/250 ISO 100

Beautiful shot of a lovely bird. Well composed and great work.

Here's another from Israel.  This is the ancient city of Tiberius by night.  The body of water is the Sea of Galilee, or Lake Kenneret.

Beautiful

Another great shot Dustin. Nicely done.

Thanks, guys.  Here's another - a dawn shot over the Sea of Galilee:


Did you try walking on the water? :)

Yes, but I'm afraid I was more Peter than Jesus  ;D

These might have helped. ;D

Amazon bird - don't recall the name, too busy shooting

Roseate Spoonbill

From Wikipedia:

It is a resident breeder in South America mostly east of the Andes, and in coastal regions of the Caribbean, Central America, Mexico, and the Gulf Coast of the United States.
