RAW defect

[Dale Villeponteaux]

Not sure what is going on with the area of roof line.
This is from a NEF file opened in ACR, but the same
defect is present when opened in Rawtherapee.

Shot hand-held from cruise ship, 100% crop
Nikon D810
70-200mm f2.8
@ 75mm, 1/100 sec, f4.5 ISO 64

Hope someone can enlighten me.

Regards,
Dale

Is the defect in the raw file or in the roof itself? It looks to me that the roof is damaged. Recent hurricane?

If you think the roof was intact, you could post the raw file or look at it directly with Rawdigger or a similar program that can view the raw data directly without demosaicing. With Rawdigger use the raw composite view. DCraw is free and can also do this.

Congratulations. Funniest thing so far today.

To BobShaw: if you think this if funny, you ought to see my photo library full of screw-ups. Which is why I don't have a viewable portfolio, a word too pretentious for my efforts.

To Bill: same in Rawtherapee, which I understand is a tweaked DCRAW. Don't have a website, and the entire file is 21 mb so don't know how to post the raw file. No recent storms in the area, otherwise know nothing about any possible damage. I was
simply taking pictures of what I could see from a cruise boat. I have another photo with a similar flaw which I will post separately.

Two more details from two different photos of same church. This in in same general area as house, so it may, after all, be storm damage.

You need to link to the raw file.


A QUESTION FOR MODERATORS: I am a registered member and have posted several times. Why do I have to answer a list of verification questions every time I post? It is more than a little annoying, and I've never been on another forum that required this of registered participants. WHY??

That's a glitch and they are apparently working on it.

If the roof was continuous and there was a defect in the file then the missing area would be white, or black or pixelated or some strange thing. It would not magically Xray through the roof and paint in the rocks and bushes behind where the roof was in it's pristine condition.

And that concludes the matter beyond any further discussion.

But an interesting illustration of how the brain/visual system operates - we have our standard reference points that everything else is interpreted according to, and apparently a straight roof line is one of these. Is this the same basic mechanism from which most conspiracy theories originate?

In both of these examples it appears that the roofline of the offending building is being blended into an adjacent structure - in the top image, the peak of the roof appears to be joined to the adjacent rock face behind it, as if the building is built into the hillside.  In the lower image, the edge of the roof is joined into the vertical face of the building next to it.  In both cases it appears that the joint is filled with light-colored mortar or something that fills the discontinuity between the roof and the structure into which it is being joined.

The fact that there is rock visible behind where the roof should be suggests that this is the case.

Thanks all. I was concerned it was the camera
or my mistake. Insecure about camera and capture since
still on learning curve with new camera.

Don't have a website, and the entire file is 21 mb so don't know how to post the raw file.

There is a site which lets you put big files up for others to download:

http://www.dropbox.com/

Never use it myself - others here can probably tell you how it works.
