Try Google Goggles if your phone can do it. You take a picture and Google looks up what it is. You mileage may vary but it works for reasonably well known location even with not so direct framing.

I have had some success posting pictures on Flickr asking for help identifying what it is, tagging with anything relevant possible.

I think you want to go one of two directions one this: Pick an image that only needs one major adjustment, which is the one you're showing. If you're demonstrating cropping, pick an image that's good in all respects except for cropping, so that your example focuses only on the crop. I'd go in this direction if you're demonstrating only one or two ...

You could try using TinEye Reverse Image Search to see if there are some similar pictures, perhaps those have some description nearby.

As long as the subject is supposed to be the little phone-booth-monument-firepit-grill-whatever-thing in the lower right, then yes, it's a good example of the rule of thirds. Unfortunately, it's also not a great picture. The rule of thirds is just one compositional technique, and it works only to the extent that it supports the technical and artistic aims ...

Searching for photography "behind the scenes" takes you to a variety of sites where pro and amateur photographers explain how a shot was done. DP Challenge also has a "How'd They Do That" section.

Find out the capture date. Then check on shots you took before and after this one. Also be sure to look into your calendar/diary (if you have one) to see where you were at that time. That's the only way I can think of.

From dcraw's FAQ: Where can I get an assortment of raw photos to test my software? Try raw.fotosite.pl, www.rawsamples.ch, and Glass Lantern RAWpository. A "full review" at Imaging Resource usually includes a few raw shots. For the complete dcraw test suite (every camera supported by dcraw), I sell a 3-DVD set for $700 and web-based ...

Here are many samples: Pbase.com Out of the 16k photos there, I'm sure some are with a d700. A bit hard to narrow down the search there, but still, a good way to get some impressions. For what it's worth, Bjørn Rørslett did not particularly like this lens in comparison with the 200mm or the 60mm, while Thom Hogan doesn't understand the point of a 60mm, ...

I don't think so. The reason is that rule of thirds relates to the positioning of your subject, but the subject itself has to be isolated by some means - contrast, color, focus blur, motion blur - anything to make the subject, well... a subject. In your picture I'd say the subject is the overexposed center as well as the two objects along with that. It ...

This is a GIF file. A feature of GIF is that it can have multiple images stored within it and it will rotate through them. It was originally developed by Compuserve to allow for images to be loaded across types of computers which formerly didn't have common image formats (thus the interchange in the name). Interchange does not related to the fact it can ...

This is a .GIF (Graphics Interchange Format) image. This format allows the creator to have the images swap (although this only happens on preset time intervals). This format is one of the formats commonly used on the internet, especially for animations.

Usually this is an option by the user posting the picture. Flickr for example - you can choose to show or hide the EXIF data on photos on your own stream....

You can use wget to easily retrieve images from any web page or recursively from a hierarchy of web pages. So you need not restrict yourself to FTP sites, although wget works fine with FTP sites as well. See the wget manual. This page describes how you can filter by any type of file you wish to download. You will in all probability get a few extra graphics ...

If the photo was geotagged, then at least you can find out where it was taken. That might be enough to help you identify the subject. (In this case, it almost certainly would, as it's a landscape shot). Some cameras have GPS/geotagging built-in. Some can do it with an add-on module. If you have synchronized clocks and a standalone GPS, you can get software ...

In ISO comparisons you need to have a bit of everything, shadow, good range of mid tones, and some highlights plus a range of colours. This shot has all of that, which is why it's an ideal shot to analyse how well a camera deals with various ISO settings. Basically for any performance analysis in a single shot there needs to be as wide a range of colour, ...

There are some HDR galleries here, which are under the Creative Commons license, so you could use these for experimentation. They are already in .hdr file format. http://pfstools.sourceforge.net/hdr_gallery.html There is a series here of raw JPGs you can use (see the related files below this one). Also Creative Commons. ...

Your search string is rather specific. Try removing some of the attributes to find a broader range of photos. Here's a search on flickr for "D600 80-200 f2.8". One for "D600 80-200". These might not be exact results as there are a few different generations of the 80-200mm, but should provide a close approximation. Pixel Peeper also has a search similar ...

Have a look at deviantArt. If the user provides a photo with exif data there, it is shown on the lower right of the picture display page.

Fotki show EXIF if the user desires My photos on Fotki have limited EXIF accessible by clicking a link next to the file. However, if you click the "Download original File" icon at top right of the image. Thusly you'll get the uploaded original (if available) which may have the full EXIF embedded. Whether any photos of mine are worth learning anything ...

I have posted some hdr source files packs on my DA account. Each pack consists of a number of lossless TIFF images for use in the making of a hdr image. Here is a link to the packs: HDR Source Pack Link

The pictures might have the exif data despite not being displayed wherever they are being hosted, this website can help see the exif data of a picture if you have the desire to know what's "behind" it. Also there are plugins for Chrome and Firefox that allow you to see a picture exif data.

This is a guess, but the B+W image looks like near infrared and the color image is apparently some other sensor data colorized to make the small variations more noticable to humans. The colored image might be something like sea height from nominal, which is usually correlated pretty well to surface pressure.

Apart from pointers given by asalamon74, for many,good raw images here is what I found: http://www.cs.tut.fi/~foi/sensornoise.html Also one of the URL mentioned my asalamon74 was broken, here is the working/cached version: http://replay.web.archive.org/20090121110307/http://raw.fotosite.pl/

It's a 1:1 lens, so that means that the size of the subject will be the same size on the sensor. Meaning, for example, a 10mm x 10mm square will project exactly 10mm x 10mm on the sensor at the 1:1 focus point. To go beyond that, you need extension tubes or multipliers. Anyways, reviews on the lens rate it very high. Like most macro lenses, it's razor ...
