I bought it in 2012 for $1429 when B&H had instant rebate ... but for the past year or so I notice that B&H is having more of the mail-in-rebates with great prices than the instant rebates, the instant rebates they've had so far in the past year seem to be not as attractive.

The mail in rebates are from Canon, not B&H.  For a few years Canon would have "Instant Rebates", but in 2013 switched back to mail in rebates.  I bought a 24-70 II this way around Christmas time.  The rebate was done by a company, and I received an American express gift card.

It's a wonderful lens.  I am not aware of anything better coming in the near future.

HDR - High Dynamic Range / Re: Post your HDR images:
« on: March 20, 2014, 12:03:09 AM »
Yes, very nice to me, too. May I ask one question. What does "single image HDR" exactly mean? Is it processed in some different way?

It means to use a single image to process in order to achieve that shot, instead of using multiple shots. For example, the surfer picture would be impossible to achieve in three different exposures and shots. What he did is raising the shadows while still maintaining the high exposure areas. There's also tweaks with some of the buttons (depending on the shots, which might include contrast and clarity, giving a boost and punch to the picture), in order to achieve the same effect as retaining all dynamic range within the picture. The weakness would be that this is dependant on the dynamic range of the camera, while the strength is that it's usually sharp and less variations introduced.

Actually I knew that it means to process a single shot instead of multiple shots. I just thought that the dynamic range of a single shot depends on a camera and you can't achieve more then that.

Perhaps this term means that someone use ETTR technique and then, during processing get better results compared to normal exposure.

Well, one thing that gives and HDR it's look is tone-mapping.  Or local contrast.  There are different ways to achieve it with a single image, but my preference is Photo Matrix Pro HDR Software.  I just love the results and find it really easy to work with.  So technically the Single image HDR does not have greater Dynamic Range, just greater contrast, but the result can be very nice.

One thing I like to do it process a photo normally with Photoshop, and Also with Photo Matrix Pro.  Then I layer them and adjust the transparency of the top layer to achieve a blend I like.

These are single image HDRs, (or as another forum member told me: Lies! Not HDR!

Technical Support / Re: Newbie needs help: Tamron 150-600mm

The pictures look good to me.  As some have already mentioned, technique is important.  Do you have mirror lock, have you tried it?

Something to keep in mind is with ultra long lenses, you are often photographing things so far away, atmospheric issues come into play.  I shoot a 400mm f2.8IS with a 1.4X and sometime 2X converter.  At something like a surfing competition, I will often be disappointed by the image quality at 800mm.  But much of that image quality is the amount of moving heated atmosphere boiling between me and the subject.  In fact my 800mm photos in the early morning are much more crisp than later in the day.

Look at these 2 images and you will see the difference a few hundred yards of atmosphere can make.

Tex, nice flashback there, and I understand your suggestions, but prints are not cheap once you get to 8x10" or larger.  All big prints aren't posters - most posters are printed large on cheap paper using 4-color printing - large prints are printed on heavy paper using more sophisticated printers.

Also, sure OS-provided calibration tools are better than nothing, but are pretty worthless in terms of getting accurate prints.  For $80 or $90, you can assure yourself of accurate prints, vs. spending that much on wasted prints that you're not happy with because they are too blue, yellow, red, dark, light, etc.

Also, I don't see it as diagnosing a problem he doesn't have because an uncalibrated monitor will lead to problems, and the bigger you print, the worse it gets.  While most people don't need a full-blown ICC workflow, I think monitor calibration and a printer who uses ICC profiles is the minimum you need for good quality prints.  For many years, that's all I could afford, and I never had to re-do a print.

Ok, so in your initial post you say 'Are colorimeters really necessary?", and now you are lecturing me about how necessary they are.  I have a Spyder 4 pro, and use from time to time.  I think the type and grade of monitor are just if not more important.  There you win, you have convinced me!  My largest print is 25 feet wide and hangs over the tourism bureau at the local International  airport.  I did not make the print, they just bought the image.  I hope they did not print any 4x6 or 8x10 test first, those can be expensive.

If you want seriously want to argue with someone about "the definition of a poster", you have the wrong guy.  I am more the photographer type.

A bit snippy in here!

To the original poster.  What are you making posters?  Seriously, it not clear iic you are printing something at walgreens to go on your awl, or or ordering 10K prints for a national advertising campaign.

Have you taken steps to calibrate your monitor via software?  Have you had some sample size prints done and found they did not match?  These do not have to be the same size to check colors, just the same process.


Hi TexPhoto,

Thanks for the response.  Really stupid question but what exactly is the definition of poster?  Is it basically just a much bigger 4x6 photo you get from CVS?  Does a 20x30 print count as a poster? (I'm not trying to be a wise ass btw, I'm really asking).  I'm basically just printing for my own home, for me to look at and possibly give out these larger prints to family and friends as gifts.

I have not taken steps to calibrate my monitor.  I realize this is a must and if I don't do it I'm basically waisting my time trying to guess what the prints will actually turn out like.  It doesn't seem like there's a way around this and I will just have to bite the bullet and spend the money to get a calibrator.


Both Mac and windows have preference panels that will let you calibrate your monitor.  Is it as good as a hardware calibration device? No.  Is it better than nothing yes, way better.  http://windows.microsoft.com/en-us/windows7/calibrate-your-display

Prints are cheap.  Go have some made using the process you intend to use for the big ones.  You are trying to diagnose a problem you don't have yet. 

Or to sum it up.  You will never learn to swim standing on the pool deck.

What is a poster?  It is that sheet of paper on the wall that makes life worth living:

I would add a real manual mode where the meter did not work.  So I could stop listening to my goofy friends telling me "You are not really in control of the camera if you are not shooting manual" (while they use the in camera meter...)  This could e caller "Real Manual", or "Shut Up - You Hipster"

Oh and you could not change ISO or see your pics until you took 36 pics and paid $10 to photo hut or someplace... :)

Lenses / Re: Good lens for hiking
« on: February 28, 2014, 05:30:30 PM »
My walk around/hiking kit 5D3, 24-105mm, 8-15mm, 300mm f4 IS, 35mm extension tube, 77mm cir Pol, 320 EX flash, Lowpro 200 sling, carbon fiber monopod, gorilla pod focus.  Now I am not hiking overnight, to me that is camping. 

I like having this wide range of focal lengths, and all of this is pretty light.  I like the 320EX over my 480II because it has the video light, and is just smaller.
