Barred owl under difficult conditions... in the woods, heavy overcast and light mist, and just after sunrise, not much light to play with.
7D2 and Tamron 150-600 at ISO1600, F6.3, 600mm, and 1/320 second handheld. I was very surprised that the shot came out as well as it did. Resting the camera against a tree really helps to stabilize it.....

BAH! Humbug!
Is she single? The Local Lion is still a bachelor and she seem to have a proper arrogant and aristocratic attitude  :P

She is old and cranky...

Hi everyone,

I have a question regarding options for long-term archiving of RAW files.

What are the advantages and disadvantages?

I am asking, because Canon might change its RAW format and optimise it for upcoming new cameras, and sooner or later RAW converters may drop support for old RAW files (considered outdated). I don't think, this will happen any time soon, though. DNG seems to be comparable to PDF/A, which is now the preferred format for electronic archiving of documents.

In another thread it was recommended to always keep the original RAW files, because RAW converters improve over time, and converting old RAW files with new converters would potentially give significantly better results than what was possible a few years ago. The question is, how long will old RAW files be supported in new converters.

But the same questions is valid for DNG, too. If I would convert all my RAW files to DNG, now, will this be a truly lossless conversion? Or could it be, that DNG conversion improves over time, too? And: How much does conversion from Canon RAW to DNG depend on the converter? Will Adobe products give different results, than, say, the DNG converter that comes with open source packages, such as Digikam/Showfoto?

I have no experience with all of this, but I am planning to archive my images, soon, and I just reading about backup and archiving strategies, formats and so on. Therefore I am very interested in your advice. Thanks in advance!

P.S.: Of course, I have written http://www.canonrumors.com/forum/index.php?topic=3113.0, before posting.
Save your files and save a current copy of DPP that supports them.... that way, even if support is dropped in a future release, you still have a version that will work.

EOS Bodies / Re: More 7DII focus problems

Think like a rocket scientist -- the rocket will not be very beneficial to a mission aimed at an enemy plane if it suddenly swerves because a bird crosses it's path, and shoots down a pelican.

Or, say I'm trying to shoot that pelican flying by, and a surface to air missile passes through the scene – if I've configured the tracking sensitivity and speed options appropriately, the camera will ignore the missile and remain locked on the pelican so I can continue taking pictures.  Of course, with SAMs flying around, ducking for cover or running away might be better choices than taking pictures.  ;)
did someone mention DUCKing for cover?

the incredible display of ego around the comment about his picture being the best a Canon sports shooter could expect from it . . .   Just a quick look around other reviews should have told him that others are not having the same difficulties he had and should have made him think again before hitting that publish button.

I think you've touched on the key here: so many photographers hold up their own personal experience (anecdotes) as examples of what can be done and what can't, what should be done and what should not, and forget that their personal experience may not match the experiences of others.  While personal taste is appropriate for the artistic component of photography, it's more an exercise in engineering to decide how to use the equipment to collect the most and best data from each click of the shutter.

I guess this is the difference with the scientific community.... peer review....  Do your tests, compare them with others, and if there is a discrepancy, try to figure out why...

Thanks Don, Orangutan, the Internet is a wonderful tool and I've always enjoyed the fact I can read so many reviews but I think being reliant on them or not putting them into the right context is a danger in itself and this is a great case in point.
Exactly!

When I got my 7D2 I rushed out to take pictures.... and they sucked! I saw other people taking great pictures and asked myself why. Then I read and re-read the AF manual and "magically" my pictures improved. I played and practiced with the camera, and they got better. I AFMAd the lenses and my pictures got better.

Rather than saying "this camera is a piece of crap", I said "what am I doing wrong" and learned how to use it. For many, there is a need for instant gratification and a reluctance to invest the time to learn..... and it is those people who blast a product not because it is bad, but because of their own shortcomings.

There is a saying about how a skilled carpenter with crude tools can produce finer work than a klutz with the finest tools.... I think it holds for photography too.

......
We had a FedEx order that went from New York to Atlanta to London to Atlanta to London to Atlanta to London to Atlanta to Montreal to Ottawa..........
That's pathetically humorous.
Sounds like some clerk in Atlanta had never heard of London, ON, and again........

Maybe they thought it was London ON (the Thames)?  I think that they have operators who create a routing bar code that gets affixed to a parcel.  From then on, that bar code directs the package, so it can create a mess if everyone involved just ignores the need to fix the issue.
It was never supposed to go anywhere near London Ontario...... that's what made 3 side trips across the Atlantic to London, England so much more puzzling...

the point is, you can't hold the store (B+H or Adorama) responsible for the incompetence of the courier....

Photography Technique / Re: EC - adds or subtracts light?

For those somewhat less technically  or mathematically inclined...

Put camera in live view.... push compensation button, turn thumbwheel. One direction (+) the exposure gets brighter, the other direction (-) it gets darker...

Until the end of the year, I have superpowers too and feel free to write stuff like "just afma your lens" or "if your 6d's af doesn't work just fine, you're not up to the task" instead of trying to present a differentiated opinion :->
I recently got a 7D2 and was not very impressed with the images.... The AF did not work "just fine" (obviously I was not up to the task :) ). I had to resort to RTFM and playing with settings before it started to get acceptable... and then I AFMA'd my lenses and after that, WOW!

One of the problem with complex systems is that there are a lot of variables to get right. When one jumps from a 9 point AF system, (that really only worked on the centre point), to a 7D2, there is a steep learning curve. I know many of us expect things to be perfect out of the box, but the reality is that most of us need to put in some time and effort to understand and get used to a new system. It's not knocking people, it's just the process that some of use go through when learning.

I think that most of the people on this forum try to be helpful. There are some obvious exceptions, but most are trying to help. For many, it is in a second language so the wording may be a bit imprecise, but who cares? ... They are trying and their heart is in the right place, so THANK YOU!!!!! to all who try.

Marsu42 - I watched KA2, like, just, 3days ago. Enjoy your Super Holidays dude.

Yup, thanks, I'm enjoying it!

Btw: KA2 didn't really impress me, the first one imho is much more fun even if it is heavy on college humor.

What is KA2 ?

Wow! Thanks for the replies folks, that was unexpected. :o  Sorry about posting in the wrong area.
Health issues have put an end to my Photography. >:( Consequently, I have lost interest in my research lab.
Of all the people who could have responded, the five who have, I have the highest respect for each of you. Its kind of spooky...

Marsu42 - I watched KA2, like, just, 3days ago. Enjoy your Super Holidays dude.
Valvebounce - Hi Graham, happy to be helpful man. All the best to you and yours, yeah!
Mt Spokane Photography - Hope you can recover some of your Polaroids. I've had some experience, maybe I can offer some tips/tricks.
distant.star - I'm not Jack. But I thought it was by Ray Charles ? Still one of my fav's anywhoo.
Don Haines - Thanks for the info', and interest.
CR Backup Admin - Thanks. I can appreciate your 'modus operandi'.
Hmm, so maybe I'll stick around a bit longer. Stay tuned for more Foot-In-Mouth action. ::)

Safe and happy holidays to all of you.
Glad you are going to stay.

BTW, did you pour your own glass? I must confess to having given the occasional thought to trying the charcoal bbq method to melt a silica mixture into glass and then to try pouring it into a mold and grinding a simple lens or two out of it.... make a telescope like Galileo :)

I've never had one lost, but I did have one B&H order go awry.  UPS ground from their NY warehouse to Boston is overnight, but I watched the tracking updates as the package went from New York to Deleware to Philadelphia.  Last I checked, Boston was in the opposite direction.

I called B&H, they sent another shipment that I received the next day.   :)
We had a FedEx order that went from New York to Atlanta to London to Atlanta to London to Atlanta to London to Atlanta to Montreal to Ottawa.... In hindsight, B&H could have used a bicycle courier and it would have gotten here in half the time, but this was most obviously the fault of FedEx...

EOS Bodies - For Stills / Reikan Focal VS Dot Tune to AFMA lenses on a 7D2
« on: December 21, 2014, 01:19:42 PM »
I have heard claims that "Dot Tune" was a reliable method to AFMA a lens. I have also heard claims to the contrary. Most of those claims have been long on opinion and short on data, so I decided to give it a try myself on a 7D2.

The results are as follows: (under incandescent lighting)

150-600: dot tune (150 +9) (600 +14) - Reikan   (150 +5) (600    +6)
  70-200: dot tune ( 70 +7) (200   +4) - Reikan   (  70 +2) (200    +3)
  17-55 : dot tune (  17 +4) ( 55    +3) - Reikan   (  17 +5) (  55   +9)
   10-20: dot tune (  10 +4) ( 20    +9) - Reikan   (  10 +5) (  20 +17)
      100: dot tune (100  -8) - Reikan  (100 +5)
       30 : dot tune (  30  -2) - Reikan  ( 30 +1)

I changed locations, repeated the test and got the following: (under flourescent lighting)
150-600: dot tune (150 +11) (600 +17) - Reikan   (150 +5) (600    +6)
  70-200: dot tune ( 70   +7) (200   +5) - Reikan   (  70 +2) (200    +3)
  17-55 : dot tune (  17   +4) ( 55    +3) - Reikan   (  17 +5) (  55   +9)
   10-20: dot tune (  10   +3) ( 20    +7) - Reikan   (  10 +5) (  20 +17)
      100: dot tune (100   -10) - Reikan  (100 +5)
       30 : dot tune (  30   +1) - Reikan  ( 30 +1)

The observations are:
1) The Reikan values stayed the same between the runs
2) The Dot Tune values varied up to 3 units between runs
3) Reikan and Dot Tune only agreed once.
4) Reikan and Dot Tune can disagree by up to 15 AFMA units

If you look at the discrepancies under the two runs.
incandescent - 4,  8,5,1,1,6,1,  8,13,3
fluorescent    - 6,11,5,2,1,6,2,10,15,0

it appears that Dot Tune is affected by fluorescent lighting.

A quick visual verification of the extreme cases indicates that the Reikan values are far more accurate that the Dot Tune values.

My conclusion. At least on a 7D2, don't waste your time using Dot Tune on your lenses, get Focal and do it right.
