I understand the tikz package is a very powerful tool that permits annotation, but for this part I think a WYSIWYG tool might be more convenient as as each figure/image is unique and a little more complicated than slide layouts. A lot of the arguments "for" Beamer is the pdf format, but I often print my Powerpoint/Impress slides to pdf anyway so that's a moot point for me. So this is one less hassle, unless the picture is in gif format, but I would say those cases arise less often. Update: Thanks for bringing to my attention that jpegs are accepted by pdflatex. Is it better to saveīack to a png and let Beamer do the conversion?

when annotating, I often "place" the image inĪdobe Photoshop, draw over it, and save as pdf.(is it inefficient)? Since the page size of Beamer pages are much smaller, does that generally make raster images less readable? how well Beamer handles images(pngs) in comparison to Powerpoint/Impress.Have you deliberated such a decision and what has been your experience? Can you also comment on However, I'm more comfortable with Beamer because I don't have to rely on my unreliable hand-eye coordination to place and align figures, and you know which figures on the hard drive are included in the presentation because of the explicit \includegraphics command (as opposed to importing figures from the menu bar in Powerpoint/Presentation). With Beamer, you additionally have to convert jpegs to pngs for pdflatex) and bring in an external tool (e.g., Adobe Photoshop) for annotation. I see advantages for using Powerpoint/Impress for slides heavy in images/figures: you can often copy figures in OSX Preview and paste into Powerpoint/Impress without having to explicitly screen capture, and download figures as Powerpoint slides from online journals. Some amount of equations but probably less (by slide count) than the images.

I am preparing a seminar course and will be showing a lot of figures: photos, screen captures of journal figures, etc.
