My earlier photos on Flickr did not have the camera mention, and so I searched high and low on how to show my gear :) Here it is:
- After resizing your image on Photoshop CS5, click on "Save for Web and Devices" under the "File" tab.
- A window will appear. Under "Optimized" tab, select "ALL" for "Metadata".
After uploading your pictures on Flickr, the camera model will automatically display on the right panel next to the images.
