The difference between a .CR2 or .NEF file and a DNG is that you can work the RAW file and then save to DNG and it appears unedited, you have clearly already edited the Canon file. What tiny bit of credibility you had due to your obviously limited but deep knowledge of one specific of a sensor has just been blown out of the water.

Mikael, you are an irrelevance.

Now I'm interested. Please show me a set of files - one .cr2 and one .dng made from that cr2 file - where the image data inside the DNG has been significantly altered...?

Of course it can be done. I could change the content of just about any raw file from any camera maker. Canon and some others have a control sum data tag that is supposed to protect against that kind of tampering, but that checksum encoding has been cracked since several years. So it's definitely not impossible, it just takes some work.

What I question is the general availability of those tools, and that you think that just about anyone can do it. AND the fact that you erroneously think that any normal program can change the image content of a raw file before saving it as a DNG. Yes, some EXIF tags may be repositioned, and some extra data may be saved - but the original image data is copied in a bit-perfect way. Bit-perfect as in "no single bit of the resulting image surface has changed between the original raw and the dng".

(actually that isn't 100% true, only 99.999% - Since Nikon and also Sony can use a kind of gamma / area coherency compression when saving a raw file, round-off faults in the conversion can appear since the DNG is LS-JPEG compressed, without gamma. That is, errors on the scale of +/-1 bit in a 14-bit file, or errors more than 13Ev down)

But still, show me the two files where the DNG has been seriously and provably tampered with. YOUR files, not someone elses.

agree... i think that he thought that we have no way to find out or compare the two files.  he is totally wrong... LOL

Could a mod move all the Mikael Canon vs. Nikon stuff to some separate, dedicated thread for that topic? I would really prefer we don't destroy ANOTHER thread with the same old debate. People HAVE been asking for Mikaels original RAW files, but that discussion really doesn't belong in this topic. It belongs elsewere, isolated, in its own little world where the debate that will inevitably rage on won't ruin any other peaceful discussions.
+as many as I am allowed. He is destroying the fun of being here.......
agreed

"...meaning of sensor physics = read out noise and why banding occurs?"

i am laughing my a*s off when reading your "meaning of sensor physics".

183
you are a fanny man
I got this answer
what shall we do? what shall we do?
and stop accusing me, you will lose

I haven't accused you of anything, so I have nothing to lose. Try send each individually, duh! The Canon file will 100% come down I email them often. How big is the D800 file?

use rapidshare or mediafire instead...

184
yes Im paid 40000USD / month + what ever gears I want.
ugly? Im showing the different sensors characteristics, I have aspirations to make the picture quite

yep, those are ugly.  not those images in here.  i am saying those images that you have taken for universities and images that you have posted on you facebook (if they are all the right one).
yes they are, but I have been living on this ugly pictures as a photographer since 1984, how about you?

your mail box was to small

taking images is not my career though, but i know that i am better than you from taking picture to probalby science (chemistry, physics, math, programming languages, you name it but not biology) too...

REALLY, SHOW ME YOUR BEST OF BEST IMAGE AND DO NOT GO OUT THERE AND JUST STEAL LIKE YOU HAVE DONE AIITE...  I DO NOT JUDGE IT MYSELF BUT I WILL LET SCOTT KELBY (A PHOTOSHOP MASTER AND NIKON SHOOTER) JUDGE IT...

you do not understand  the difference, I can use what ever shutter speed . f-stop I want  with one exposure, tell me how can you do the same with the camera on a tripod and taking 2 or more exposure. ?    a example: running people in front of the camera and sunset behind, or fast running cars  or what ever

1. yes, those posted images were taken only one exposure and no repeat shot
2. with tripod or without tripod, you can take hdr depending on you iso and skill, want to learn? learn yourself from jay maisel.
3. people in my picture were not my subject, therefore, i careless.  however, i consider that as a lucky thing since it is add more live to the image (imo)

sigh... i am getting tired of talking to old guy like you...

and ? Nikon has still 14 stops DR and Canon 5dmk2  11 including pattern noise . 6D has 11.5 stops DR and less pattern pattern noise than 5dmk2 , what is it you do not understand?
and that picture you show has no DR at all, flat and rather ugly ( and remember that is my personal view on your picture)

those images are better than yours though... i am not that stupid to pay for that much money per month even though my pay rate is more than double (if i do not want to say triple) the shown amount per year...

did i say that i am careless about that one and i do care about clean noise at high iso, not full of color noise like nikon?  if you care, keep it for yourself since number of us in here have shown no appreciation about what you are talking about.  why making noise, nikon hire you to say that in here?

and  the results look like this if I lift the shadows even more. Nikon d800 to the left and 5dmk2 to the right
THIS IS the results of 14 stops DR with clean shadows in  lower levels and compared to 11 stops Canon DR  with banding and pattern noise.

once again...

1. yeah we do all care about dynamic range.  BUT noise in low light is what we care the most.
2. if we want more dynamic range, we would perform hdr shots
3. most of us do not want details of the sunny sky at noon, except you

note:  if you are that good, then please explain why mr. micheal freeman shot a landscape with f/32, shutter .5 second and 20mm focal lengh (probably somewhere in page 15-20 of his book).  AND STOP TALKING ABOUT THE "DR" THING SINCE MOST OF PEOPLE IN THIS FORUM WILL PROBABLY NOT LISTEN NOR RESPECT YOU BASED ON GIVEN INFO.

one again -you have more options with 14 stops DR, you can handheld the camera  and take one picture and develop
 the raw file after high lights and shadows and put them together , with out tripod  and static motive, not moving motive
what you then  are writing you must explain to me, is it you who not understand the benefits of large DR or do you speak for all  all people here at CR that they do not think large  DR  or small DR with banding and pattern noise  are a issue

what do you mean

i careless about that one since canon offer good low light iso.  like i said if i want to get more detail then i am using hdr *bracketing" and yes, i can manage myself to handheld up to 1/5s.  my images are mostly snapshot but it probably look better than yours and your friend "Aglet".

these images: one was taken with my mouse pad to test handheld (at 1/5s) ability (turned off all light in my room, the only available source light was from my notebook. taken with my canon 7d).  another one is the only one of my snapshot landscape with cokin graduate filter (taken after 4 months of using dslr).

note:  i am traveling for work; therefore, i download these images back from my personal site...

Seriously?!?  This is how you think?
Then I think you do not understand the whole concept of artistic intent - which is just fine since you are defending using tools that limit artistic expression.
Some of us prefer to work with hardware with less limitations to provide us with a greater latitude of creativity.
Ultimately, it seems to be this is what it comes down to; some of us want to manipulate our images and some of you are happy with them out of the camera.  Artists vs snapshot documentarians.

DING!
And there's the bell!

Another round begins with Fact moving to the middle of the ring while BS tries to circle around and gag Fact with the odor of BS.

Fact dodges, moves to get some fresh air but it's pointless, BS is EVERYwhere! Boy can BS ever move!

Fact relies on his standard trick, facts.  But no matter how many facts he throws, none of them land a solid hit on BS.  Even when Fact comes out with new facts, BS is still unfazed.  What a fighter!

Can BS defeat Fact!?  We've gone countless rounds and there's still no clear winner.  Every time Fact appears to win on a technical, BS rises to the challenge!  How long can this fight continue!?  Can Fact ever keep BS down!?  Will they declare it a draw!?  I don't think so!  Neither Fact nor BS will tolerate the other coming out on top.  This promises to be a lot longer fight people!

DING! DING!

And there's the bell again!  Fact and BS are off to their respective corners for a little rest and words with their coaches.  Another round will start in a few moments, folks.  Don't leave your seats!
This is a battle you don't want to miss!

And now a word from our sponsor...
Kodachrome!


can you prove it to me that you are artists.  yep, i am still taking snapshots but i bet those snapshots will proably turn out better than yours.  PROVE ME THAT YOU NAME IS ON ONE OF FAMOUS LIST, MR. SHOOTING SKY AT HIGH NOON.

http://a2bart.com/gallery/new/new.htm

AND YOU CALL THESE IMAGES ARE ART?  I WAS ABOUT LAUGHING MY ASS OFF TO THOSE SNAPSHOTS EVENTHOUGH I DO NOT DO LANSCAPE AND ABSTRACT.

Note:  For some of your images, you should take a look at Jay Maisel images, compare it (since they are somewhat identical) and then think why you are not there yet Mr. Artis.

OK
You can try to down load  raw 2 files, one from 5dmk2 and one from d800, sun set, both cameras exposed the same regarding time/f-stop and 100iso and  exposure after the high lights,  to reproduce the high lights intact , then Im adjusting  the lower levels / shadows  with the  same  parameters in  camera raw ,  and  later  the same adjustments  in photoshop with lifting the  lower levels / shadows  :   look at https://picasaweb.google.com/106266083120070292876/5dmk2AndD800DRSunSet


here is  the raw files
link https://drive.google.com/#my-drive

and the results looks like this with the same parameters regarding high lights and shadows , nikon d800 to the left and 5dmk2 at the right

well... that is not a appropriate link.  that kinda link will link to home drive of whoever has gmail account ("#my-drive".

Third Party Manufacturers / Re: D7000 replacement in April...
« on: February 06, 2013, 08:33:24 PM »
I heard you, and keep going and try miss credit me.
which one will you have d800 and 1dx? 5dmk2 and d800, 5dmk3, 5dmk2  and d800 a test noise  made by the _suede and me published at Dpreview.
sun set 5dmk2 d800. I have 100 of them , but I must find them
choose, in the mean time Im going to sleep the time is 0228

remember to find them upon waking up tomorrow and YES, WE ALL WANT RAW FILESSSSS...

No that is not my test pictures , but you can se  similarity, any  problems with that?

you are on this forum for almost a year with those test images, not talking about other forums yet.  now you are saying that those are not yours.  however, re-create another example and send RAW files to us then we will talk more about it.

hate to say this out but if you want to challenge about exposures (one shot only, no taking a look at histogram and re-take.  yep that is the way that i am forcing myself while learning), i am ready whenever you have time to travel to LA or Arizona for photography events, especially in this coming MAY, THE BIG PHOTOSHOW.

note:  no challenge on strobist since i am just starting to learn...

Sorry guys, I have not been around for a couple of days so now I see the "D7000 replacement in April..." topic and open, read last two pages without seeing anything about the D7000 or its replacement. Going to read from the beginning to see how the topic developed...

Here's how:

Q: What was the weather like in Stockholm last week?

A: Sunny, and when I underexposed by 4 stops to capture the detail of the sun shining down on the Storkyrkan then pulled up the shadows by 4 stops to see the cobblestone detail of the Slottsbacken, the Canon 5DIII failed miserably with banding and noise, but fortunately I had my D800 with me - and look at this perfect shot!

 ;)

well with a sony sensor you can under expose so you cover high lights far above middle grey which are  usually 4 stops and both Storkyrkans golden highlights  are intact reproduced  in the sun  and open up in the shadows of the big church to se details= that the benfits  of  a large DR 14 stops and not 11 with banding and patter noise

sorry, a prof. photographers who under/over expose for more than 2 stops will not going to be earn my respect.  i do not allow myself to make big mistake in predict exposures; therefore, i have made a tool and developed my own way of seeing light.

under/over exposure over two stops? sorry to say that he/she is an un-prof. photographer.  are you one of them?  if someone wants more DR, then go for HDR with CS6 since it is available 32 bits now...

this shows that you no dot understand what I meant,and what a large DR means and exposure latitude. I have the  opportunities to under expose two steps or more and show highlight that is more than 4 steps above medium gray with out any banding and patern noise in the shadows with the Nikon and Sony sensor.

1. if the sky to bright, what do you need to show... there is nothing to show there according to what i know (i.e. sunny day at noon.  SOUND LIKE NEURO SAID IT RIGHT.  YOU WANT TO "CAPTURE THE DETAIL OF THE SUN SHINING DOWN...")
2. if sky is your subject, why do you care about other?
3. if you want to include everything in your photo?  hdr is your choice (well, sorry i have to say this.  only suck photographer wants to include everything in his/her image.  that is what we are calling snapshot.)
4. everything in this world has its own limitation, find a way to work around with it

note:  i am not sure if they are your picture that i have seen online, but if it is yours, they are just normal, nothing highlight nor telling a story...  next time, if you are going out to take photos again, suggest to take a look latest video from brian peterson posted on adorama (DO NOT INCLUDE EVERYTHING IN YOUR PHOTO)

psychologically, i do not think that you can re-learn this part since you already develop these shooting habit for number of years.
