Here's my wild guess...

Camera Make: NIKON CORPORATION
Camera Model: NIKON D40
Image Date: 2008:04:09 11:03:37
Flash Used: No
Focal Length: 30.0mm (35mm equivalent: 45mm)
Exposure Time: 0.025 s (1/40)
Aperture: f/1.4
ISO equiv: 1600
White Balance: Manual
Light Source: Incandescent
Metering Mode: Matrix
Exposure: program (Auto)

"The camera is a Canon Canonet G-III QL17, which is a fine fixed-lens rangefinder that offers an excellent 40mm f/1.7 lens and automatic exposure or full (non-metered) manual control. I used a clip-on Vivitar meter of the same vintage to get my shutter speed settings. I shot Kodak Gold 100 film and scanned with a Konica Minolta DiMAGE Scan Dual IV. Processed with The Gimp and uploaded to Flickr. "

Yeah, buddy! Well done. Isn't technology fun?
 
Maybe he used a neg attachment to "scan" the neg using his D40?

I'm not sure I understand what's your point..

What I was hoping would happen is that we would get some comments on the characteristics of the image itself that describe why it is what it is. For example, if the image is digital it would probably have been shot at a high ISO given the lighting situation. Is there the kind of noise apparent in the image that would support that idea? If the image was shot on film...what about grain. Actually, that kind of analysis of the image might not be possible given the limitations of viewing a low res jpg, but I thought it worth a try. It gets rather tiresome having to witness those endless film vs digital rants, and I thought that trying to deal directly with the characteristics of specific image might be more instructive.

OK, Do your EXIF stuff on this one: Hint it wasn't scanned:

At first blush, the Exif data appears to have been removed:

I used Phil Harvey's excellent Exiftool to extract what little data there was. If there is other Exif data in there, I cannot find it. I also used a hex editor on the file and looked it over by hand, but nothing jumped out at me.

Am I missing anything? I'm happy to learn, if you have managed to tuck away data that I cannot find.

I'm surprised. This is a 1947 Kodacrome taken with a Kodak Bantam and I copied it with my slide copier and my Pentax DL.

It depends upon how you processed the image from the DL. Some editors strip out Exif when saving (sometimes called 'Save for Web') by default. This makes the resulting file smaller in size, which can be a good thing when on the web.

Some people have also become aware that Exif data can also include things they'd prefer others not to know - like the unique camera serial number (my *ist DS includes this in the Exif data). If I had registered my camera with Pentax when I bought it, any resulting images I put on the web that still had the serial number embedded in them could be traced right back to me. This information could be used to located a stolen camera (if the ultimate buyer ended up posting photos with the camera) or it could end up being used to prosecute a person who used the camera do something they ought not to and post *those* photos onto the 'net.

Here is an example of Exif data from my *ist DS as extracted by Exiftool:

**********************************************
A lot of this information is just useless, or is only useful to some people for some reasons.

However, more information can be added to Exif data that the camera creates - including GPS location data, and then there are data fields used by reporters, and copyright data, all kinds of stuff. Of course, Exif data can be manually added to photos taken with traditional film cameras, although it then depends upon the person entering the data to get it right.

Why?

In my case, I consider future historians. If I find an old photograph at a flea market, it may be interesting, but who is it a photo of? Where was it taken? When was it taken? For what purpose? And so on. In other words, stripped of its context (a photo album viewed by a family member, perhaps), it has less meaning. But that information CAN be recorded in the Exif fields - and then it stays with the photo. In the future, anyone who looks at such a photo would know some or all of the answers to those questions, which might make it more meaningful at that time.

Just fun geeky stuff. And scary stuff, if you're paranoid about your camera's internal serial number being part of every digital photo you put on the 'net.
