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It should be noted that current answers here and on the related question are rapidly falling out of date.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.

comment What do all those cryptic number and letter codes in a lens name mean?
That would be fine with me. This is totally a community answer at this point. Whatever the community wants to do with it is fine with me.

Could you guys post ExifTool comments as answers? Preferably with a little bit of elaboration on the specifics? Thanks!

comment Adequate PPI for 12' by 5' banner
By my calculation: 1/(0.0002 * (5*12)) = 83.33 PPI. Since that usually is not an option, I would say 100PPI, yes.

@CountIblis: Could you write up an answer with that?

comment Will editing an image in a significant way alter copyright?
David's original comment is important here. We need to clarify the necessary locale, the jurisdiction within which you need an answer. Were a global community, so not everyone has the same law.

comment Will editing an image in a significant way alter copyright?
Vic, could you clarify the regions and locales the laws you are referring to apply to? We get a range of global visitors, and law may not be the same there. It is important that we are clear about the context of the laws we refer to in posts like this. For your own sake, unless you actually are a lawyer, you might want to throw IANAL in there as well. ;)

comment How do I generate high quality prints with an ink jet printer?
Sorry Olivier, I think that was supposed to be: (DPI/PPI)^2, since it's per square inch. For one row of dots, it would be DPI/PPI linear dots per inch. However, even squaring is not actually correct, since DPI is usually non-uniform in both directions...a 1440DPI printer may actually be 5760DPI in the other direction. That whole section should probably really be rewritten.

No rush. :) I appreciate you taking the time to keep the post accurate.

comment What is happening when I convert from a source color space AdobeRGB to a Canon photo paper profile?
@Kel: I don't disagree. My wording is poor in this post. I was referring to the X/Y coordinates of r, g, b primaries as they map to Lab space. I haven't worked with this stuff in years, so feel free to edit and improve if you can. Or provide your own answer.

comment What is the Base ISO of a Canon 5D MK III?
Actually, when it comes to astrophotography, on Canon cameras it is best to use full stop ISO settings. Because of the trickery Canon uses for the third-stop settings, you will not get properly linear results. If your doing milky way imaging, you should also be doing dark frame subtraction and flat field calibration. You need the most linear data you can get when doing that.

Also, remember that you can expand the height of the editing window when you do edit.

comment What do all those cryptic number and letter codes in a lens name mean?
I'll see what I can do when I get a chance. One thing I do not like about breaking it up, and this has nothing to do with it being my answer, just the value of it's contents...is there can only be one accepted answer. Breaking this up will mean all the content falls to the bottom of the page for most viewers using the default page listing. Not really sure I want to do that...

comment Why do my photos lack texture/detail/microcontrast?
What exactly are you looking for? Aside from some exposure issues...your images seem to have plenty of detail, and the color is great. There are some slight focus issues, but nothing I would attribute to the hardware...it just looks like your run of the mill micron misfocus caused by things moving in the wind, or you moving ever so slightly while taking the picture.

comment When to expose for the shadows vs expose for the highlights?
Nikon shadows will be pretty much the same as Sony shadows. They both use the same Sony Exmor sensors. Nikon actually does a better job with their RAW data, as it is true raw, not lossy compressed...so you might be able to eek more performance out of each file. Overall, though, the differences between Sony and Nikon cameras that use Exmor sensors is minimal. Your fine going with either brand. Almost everything out there these days uses Sony Exmor sensors. The exceptions are Canon, which use Canon sensors, and Samsung, which use Samsung sensors. Even MFD use Sony now.
