Mosaics are one of the most visually appealing photo effects you can create, but they also require a lot of work: thinking about the right design, gathering all the necessary pictures, laying them out so that colors and lights match... these are all tasks you obviously need help with. Luckily there are a bunch of software tools out there that can help you create a mosaic with your photos in almost no time. They hardly require any user intervention, and some of them even include a collection of ready-made images, in case you don't have enough for your own mosaic! Let's take a look at three popular examples of photo mosaic software: Mazaika, Andreamosaic and Foto-Mosaik.
Mazaika is a shareware app that enables you to create photo mosaics in a snap. It lets you use any sort of images, from 32x32 icon files to large photos from your digital camera. In case your personal collection isn't big enough, you can download special mosaic-ready image collections from the developer's website. Also, Mazaika is the only mosaic application that lets you adjust each tile individually, once the mosaic is finished - which may come handy to tweak the final result or place a specific image in a specific location as your personal signature. Mazaika has a 30-day trial version you can download here.
Andreamosaic is a freeware tool with which you can create mosaics in a very easy way. The program itself features a rather dull interface - a gray window with all the options you can select for your mosaic - but the results can be pretty impressive. Of course, you need to have an extensive collection of photos to obtain a better looking mosaic. Andreamosaic features a pre-loaded collection of 500 images just in case. The program is thoroughly documented, so it won't take you long to get the hang of it. You can download it from here.
Foto-Mosaik is also a freeware app to create mosaics. This is probably the easiest one, as all you have to do is select the folder where your photo collection is stored, and also choose the image that will be converted into a mosaic; the program takes care of everything else! Just like the other tools, the more photos you have in your database, the nicer the outcome will be. If you want to try it yourself, get your copy here.
