comment What is a “diffraction limit”?
@MichaelClark: You don't. I only did that to simplify the example, nothing more.

comment Should I go 5D Mark II or 7D?
The 5D IV should be announced sometime this year, hopefully. I suspect it will get a pretty decent upgrade over the 5D III. I haven't been excited about a Canon camera in quite some time...their IQ just doesn't hold up in an increasing number of cases against the competition (it's still good, just not excellent across the board relatively speaking anymore). I'm hoping the 5D IV gets me excited about Canon again...

comment Is there a general formula for image size vs. print size?
Magazines have very low resolution in the grand scheme of things, and personally, most magazine images look very grainy to me. I would call 200ppi too low for a decent photographic print unless your printing quite large. For smaller prints, stuff that might be held and viewed closer, you want much higher resolution than 200ppi. See: photo.stackexchange.com/questions/1715/…

comment How does software exposure compensation work in RAW files?
I am aware that not all 'RAW' formats are lossless. Sony's cRAW is actually the best example of a LOSSY compressed "RAW" format. Thankfully they offer uncompressed RAW now, and will supposedly be offering lossless compressed RAW in the future. I don't consider cRAW nor sRAW to actually be RAW however, and since neither are actually required anymore, I am only addressing true RAW formats.

comment How well do Canon EF lens adapters for Sony E-mount perform?
It should be noted that current answers here and on the related question are rapidly falling out of date. The newer Sony Alpha series cameras, including the forthcoming A6100 (due in a month or two here), have significantly improved AF compatibility with third party lenses thanks to phase detection AF. The Metabones IV adapter (and I believe a new one, probably the V?) support fast AF with Canon EF lenses, and there is a new adapter that supports fast AF with Nikon F lenses as well. Upgrading the a6000 to the a6100 when it hits the streets with a metabones will give you fast AF.

comment How do I transform an image to match another in terms of scale/rotation/aspect ratio?
What kind of contents do the images contain? If they are astro images, then any astro registration tool will do, such as RegiStar. If your images contain something else, then you may need to use a difference layer blending mode to manually align. There may be automated tools out there that can automatically align images, however I am only aware of one for astrophotography.
