Many of the blogs / Flickr streams do not publish images their EXIF data with the pictures - all I can see is the histogram.
Can you recommend blogs / samples with EXIF data in them so that I may learn from them?
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....
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.
you'll get the uploaded original (if available) which may have the full EXIF embedded.
Whether any photos of mine are worth learning anything from is in the eyes and mind of the beholder, but many have EXIFs, if of interest.
eg this one "Through the bars" has brief EXIF via link and full EXIF embedded.
Main point here is total vanishing of cage bars by locating them well inside focal length of lens, and f/1.8 DOF.
Similarly here 2000 Years! - through glass. While it's "hand held" without flash, shutter speed tells you it was VERY well braced (against glass and 'me', with me wedged against a pillar.
If a site permits saving an image it is sometimes found that EXIF data is present. If so this can then be viewed with any usual EXIF capable viewer.
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.
If you use Chrome I recommend you "Exif Viewer" https://chrome.google.com/webstore/detail/nafpfdcmppffipmhcpkbplhkoiekndck
One site that I've found particularly helpful in understanding what settings to use is PixelPeeper.com, in particular its advanced search page. On the search page you can put in various search constraints on lenses, cameras, ISO, aperture etc and have it search flickr for images that matches those constraints.
So say that you want to search for how to take a good night shot with your lens you can select your lens and put a 1s+ limitation on the exposure time and look for night shots in the results. The page displays lens, camera, ISO, focal length, aperture and shutter speed right underneath the images.
If you're browsing for inspiration I've found that users on 500px.com seem to be relatively good at exposing their photo metadata as well.
