Can you tell what make and model a person's camera is by looking at the photos they've taken?

One of my blog's readers commented that he or she was able to tell what kind of camera I was using (and he or she was correct, down to the model number) from looking at the household pictures I had taken and posted on my blog. Is this possible, or should I conclude that he or she knew this information through some other method?

Sure! Right click on your photo - then go down to PROPERTIES and click the SUMMARY tab. Scroll down and you can view lots of information. Part of that information is the type & model of camera, shutter speed, lens apeture, if a flash was used, and even the date.

Some cameras record that information within the photo, but not all photo viewers have a feature that allows you to view that information.

Take one of your pictures and open it up in a viewer and go up to the menu bar and see if you can find something in one of the drop down menus that says "information," "photo properties," or something similar.

Clicking on this will most likely give you the picture information. It will give you information like camera type, date taken, shutter and aperture speed, etc.

Again, not all viewers do this, but some do. Ulead Photo Explorer 7.0 will do this. It's under "File" then "Photo Properties"

Not likely. I can tell if a photo was taken with a 4 megapixel "Point and Shoot" style camera as oppossed to a digital SLR, 8 or 10 megapixel camera.....It's more about the focusing and number of megapixels your camera has, and LESS about the name brand or model number.

Side by side, it would quite impossible to tell a photo taken with a Nikon, Canon, Minolta or Olympus SLR camera if they are all the same specs, such as megapixels, etc....

Sounds to me like has some other inside info about what camera you are using.

On Flickr for example it is possible to look up 'More details' in the camera EXIF that will tell you not only what camera but also what exposure and aperture was used, also the ISO and plenty of other stuff. Many folk block this access but why I don't know, who cares if they have the info, not myself at any rate.

the information was recorded in the details of your saved photo online. this isn't hard information to find as most digital cameras record things such as date, time taken, model, resolution, etc. if you don't tell your camera to stop recording these things, it probably does it automatically. so the person saying they "could tell" was being pretty shady. your photo is the thing that told. not the viewer.

The make and model of the camera are of no use, it is solely the quality of the photograph that is important. Of course you can screw that person's mind up by taking the photo with a 35mm camera and scanning it

All digital cameras write EXIF info. This can be accessed via a number of ways. One being to view the "File Info" of the image file in Photoshop.

PP

You don't need any special software, just right click on the image file and select properties. That opens a window with general, security and detail information.

Just by looking at the pictures? Absolutely not. Your reader probably accessed the EXIF data.

Unless your photos had any type of information from the camera itself (any sort of letters or numbers on the bottom etc.) there is no way this reader could have known what camera you use.

Download a program called "Photo Info" from Microsoft.
