The other day my boss asked me if it was possible to batch convert a whole bunch of images. He had a folder of TIFF images that needed to be converted to JPEG images at 100 DPI. Since I was already at home I quickly threw together this little video to outline how the process is done using Photoshop.
Look for more of these sub 5-min video tutorials in the future, as I think its a great way to express a task without boring the learner with paragraphs of text.
