Like many I take digital photos and not all turn out looking great. Sometimes the white balance needs to be adjusted, sometimes I want to crop out the highline pole ruining a great nature shot.
I have a go to image editor and I must admit that purchasing through the Apple app store has allowed me to load this tool on most of my computers. However, I also make use of online image editing tools and recommend such tools for classroom use. The cost is often free and learning to use a tool you can also use at home is helpful to students.
Picnik used to be my online tool of choice. It was weird, Picnik was the tool linked from Flickr, but Flickr is owned by Yahoo!. Picnik went away. Now it is back (you can see the similarity) as Ribbet. As always, the future of a service concerns me when it seems the primary tool is free. One strategy seems to be creating a valuable product that a company purchases (e.g., Google) and then integrates (I guess this is what happened to Picnik). There is a premium version of Ribbit coming (actually, available now until the price is established) but what I am looking for is a tool for those situations in which I decide not to use the commercial tool I already own. Hence, what I would pay for a premium option must be quite reasonable. In the meantime, I am pleased to see the return of a valuable service.
