Do be aware that when getting in to alt processes, each process has its own unique response curve, so what makes a good cyanotype negative makes a lousy platinum/palladium negative, and a good pt/pd neg is marginal for albumen/salt printing. This is one of the strengths of digital negatives - you can develop a curve for each process and then apply it to create a negative that fits each process. If you want more information about that, please spend some time on DPUG, our sister site. The upside is that it frees you from having to shoot large format to make platinum/palladium (or any other alt process) prints. The downside is that you still have that 35mm/medium format look to your images, which is somewhat at odds with the look you expect from a platinum/palladium print.

But yes, as a general rule, alt process prints are very straightforward to make at home without a special dedicated facility (but it always helps - I like to keep my chemistry away from food processing, clothing and bathing areas).
