QUOTE At least I know whoever sees my photo, the color is already up to my expectation and always consistent. It is up to the person to get his monitor to the right color. That could also means he may not care about color that much I guess. It is the same thing as driving a car which is dirty+smudgy. Some prefer their car to be gleaming shine everyday but others don't care as much with so many scratch & dings around it. Should be up to the person right? another thing to trouble you on colour space and colour gamut for images uploading on the internet colour space and colour gamut explainedno point in getting the best camera and best lenses and stuffs but 1. didn't print it out 2. upload it in a wrong manner This post has been edited by ifer: Apr 12 2012, 11:39 PM

QUOTE(Everdying @ Apr 12 2012, 11:39 PM) so if its not sensor problem, and in liveview its all in focus, so something is happening when its written to the card? should be something to do with the AF module i think. Nikon has only let those NPS fellas know about this, I tried to contact Nikon but to outsiders they would only say there's no AF problem reported. But they have notified NPS members that Nikon hq is following the matter and bulletin has been issued to nikon subsidiaries to update the issue (according to Ming Thein) . and with no new shipments for the past week, I assume Nikon is sorting the problem before any new shipments are made(just guessing). Added on April 12, 2012, 11:44 pmand it only affected certain batches of D800 not all. . . Added on April 13, 2012, 12:07 amshare share pic! tokyo!!!!!!!!!!!!

LiveView using Contrast Detect, sure different when using viewfinder. If there is Back Focus or Front Focus issue, using LiveView doesn't have this problem.

Duh!!! because in liveview mode, sensor is the one focusing not the AF module. That's why normally one compare an image with one taken under liveview mode to check front/back focusing. And you fine tune your AF in your body til it mirrors the result achieved in liveview. It's not right to say liveview sure different when using viewfiner. A perfectly calibrated AF module and lens should yield identical result when compared to images capture by using liveview. And I'm talking about the AF problem for D800. Because it's known with wide lenses, the left focus points are OOF while the centre and right are not, using liveview is to check whether it was due to the AF module or sensor.

I'm saying if have problem with focusing, using LiveView sure will spot on, as reply to your statement about when they use LiveView it's spot on.

Because it's odd to see centre and right focus point able to focus properly while the left side always appear OOF. Added on April 13, 2012, 10:16 ambecause if the sensor is misaligned, using liveview will yield some odd shift in focal plane. . . . This post has been edited by hkenh: Apr 13 2012, 10:17 AM

That's why I say LiveView will yield different result and will show spot on. LoL, your reply like disagree, but then you said back the same thing back? LoL. Anyway, I think I misunderstood from your initial statement. This post has been edited by Andy214: Apr 13 2012, 10:33 AM

hmm. . . if sensor is misaligned, it's not true that it will always get perfect focus in liveview.

Ive always been on sRGB since long ago. And never bothered to try out other color space. Will give the others a try. On subject of printing, there is lots to learn about that. Im still trying to figure out whats the best print out. Hmm..
