First time out with the 7D

This is a 7 shot HDR--Just playing around, but I think it worked

And the rest---Just normal shooting:

Amazing colors!

Thanks Oren, It's The magic of photomatix.

Hi Bob


Your shots are very good. I have also a 7D & various lenses, but cannot get shots as good as yours. So I'm curious as to the settings you used for these shots. Thanks Wally. PS Your HDR shot is also impressive.

Wally,


Well, I was experimenting today so I was using alot of different settings: The HDR was was actually 6 different shots bracketed 3 Stops above and 3 Stops below. I normally like to shoot either manual or Aperature priority, I usually keep iso between 400 and 800 since I was shooting with a Circular Polarizer filter. I try and keep shutter speeds above 800 and I normally shoot with a single point focus. But I was experimenting with the Auto Zone AF and kind of liked it. I used single point metering on the bird and I think I was using evaluative (Matrix Metering on the landscapes) I had a photo instructor provide the following for his "recipe for success" which generally works, but not always---Here it is: AV mode, aperature 6.3, Evaluative metering, ISO 800, single point AF. I have found this a very good place to start when shooting general wildlife. Two things I learned today: 1, Like others have said, the 7D overexposes by 1/3 stop. So, Meter 1/3 stop below (Left)center on the meter. or adjust EV by -1/3. The 2nd thing I learned----If I do my job, this camera performsextremely well.


One more thing---I did some tweeks on contrast, saturation and sharpeningin Canon's DPP software and ultimately reduced the shots to web sized.


Here are the details for your viewing pleasure, Hope this helps.

Very nice shots Bob! I'm sure you enjoyed your first time out [H] Beautifull scenery [Y]

Thanks Jan

Bob, I think Bryan's review said that the 7D underexposes by 1/3 stop.

Alan,


Hmm, now I have to go back and re-read----but I shot about 700 shots yesterday, and when I followed the meter, I was over exposed by just a little. When I corrected to -1/3 and sometimes 2/3, the shot looked decent. But Thanks, Iccertainly don't want to misquote anyone, especially Bryan. I think I also saw this on some of the user reviews on FM.com, but I'll check.


Thanks for pointing this out.


Bob

Bob, what counts is that the shot looks good. And, if you're seeing it needs a -1/3 EC, then that's what is needed. Your shots look wonderful, by the way.

Thanks Alan I appreciate your comments, but you are 100% correct--here is Bryan's quote


" Also note that my 7D delivered exposures that are 1/3 stop darker than my compared-to bodies at the identical exposure settings in this test - thus the +1/3 EV examples. "


Now I am going togo back through my shots from yesterday (those that I haven't already deleted) and see if I can make sense of all of this----I can say this: of the four shots I posted, one was HDR, and one landscape was shot maually so they don't count, but both bird shots were exposed at -1/3 and and one landscape was exposed at -2/3rds.


Question for you and others---can camera body's differ in thier output as much as lenses can, i.e. good copy/bad copy?


Please forgive me, I don't mean to argue or justify my position--It's just that my "amatuer" findings were different than Bryans, so I am trying to understand it---all input/guidance is appreciated.


Thanks,


Bob

Beats me, Bob. Someone more technical can hopefully answer this question.

Really? 800 ISO? I guess if the 7D has good grain management, that's ok. I wonder what the significance is. Did you prof explain?

Bob,


Great shots man! How you liking the 7D? I can't wait to pick mine up at the end of the week!
I'll have to trade you video lessons for your photo lessons![;)]

Ok, resurrected thread, I know, but it's an interesting (and unanswered) question. My guess would be no, camera bodies do not have the same copy-dependent output. Both cameras and lenses come off assembly lines, so yes, there will be variances and tolerances. The difference is that for a camera, the copy-to-copy differences are unlikely to have an optical effect, since just about everything in the camera that affects the quality of image capture is electronic (where tolerances are much tighter than for mechanical components or their assembly). The primary 'mechanical' effect, I think, would be positioning of the sensor relative to the lens mount (determining where the focal plane is relative to where it should be, by design) - and any variance there can be 'corrected' with AF Microadjustment on recent bodies. All of the metering systems, etc., are basically self-correcting (due to TTL measurements) with the camera's electronics. Lenses, on the other hand, have many more components that directly affect image formation. Optical elements may have small imperfections, be mis-angled or misaligned with one another, etc.


Just my 2&cent;.

Mike, You have a deal
