Your going to need to around 300 Pixels Per Inch (PPI) for higher quality print products. See the guideline below. However, you mention 'canvas'. If that is your substrate material, then the relatively course structure of the canvas may limit the printed details and you could get by with a lower PPI. There is a lot to say on this subject, but start ...

I firmly believe you have more use of thorough knowledge about sharpening techniques than staring too blindly on the technical side of the camera. The idea behind the statement: I'd expect the down sampling to generate more blur than the anti aliasing filter ever did. The tool you have to recover the blur is just sharpening.

I'd be surprised if you saw a difference. Remember, the image has to go through a re-sizing algorithm that would cause the slight difference between an AA image and non-AA image to disappear.

The effect of omitting the low pass filter decreases as resolution increases. That's why we're suddenly seeing AA filterless cameras, we've reached a point where aliasing is no longer a significant problem. The difference you see will depend on what glass you're using, really sharp lenses will still produce aliasing, at least in the centre. In most cases ...

The answer is definitely YES but if this iPhone use only then it probably doesn't really matter as the destruction of your image is part of the aesthetic of SNAPSEED. NIK Filters make a sharpening plugin and a Analogue FX plugin for photoshop that you can use with 16bit images - as NIK make SNAPSEED then that's the direction you could go

So, the short answer if you're editing and saving from Snapseed is yes. There are a couple of reasons why this will result in reduction of quality: You've discarded data from RAW to PNG/JPG in the first place. This now gives less information for Snapseed to work with and so further edits could result in even less data, especially in the shadows and ...

Image/video enhancing to the level suggested in TV shows is simply not possible, and is actually limited by the image capturing device. That's the technology that would need to evolve first. It is impossible to gain information from a collection of 10 pixels into a recognisable object. At the pixel level, that's the final amount of information provided in ...
