It is not enough to process well your pictures and get the best software.
Nowadays, we also need or we can take benefits from so many web services. Here below my favourites ones:
Tineye: a reverse search engine to know where an image is published.
Digital Camera Database: a great tool to compare cameras sensors! And it does not only focus at the sensor size but other technical specifications too. It looks cleaner and more user friendly to me than the DXO database, whereas extremely detailed. And DP Review comparator does not go so much in details for the sensor itself.
Ipiccy: kind of free and online publisher tool. Photo Editor, collage maker and graphic designer. There are nowadays so many tools to enhance your images, this one looks interesting to me for collages and graphic designs. Consumer tool, but very useful for basic needs.
Clipping Magic: quite well done and efficient for many needs. You can use this web tool for free but the watermark on the result image will motivate you to buy the subscription. If you don’t like subscription, you can purchase and download another software on your desktop: Photo Scissors.
Photerloo: this service will post your photos to all the popular photo sites so you don’t have to, this saves you time and helps you organize your photo uploads. It is a great tool to automate your social publishing.
