Pixel Size / Resolution

good lucky meeting that requirement at 20 x 30. Took many people purport the 300dpi "requirement" when it really is about 2 x overstated.

Either you uprez to 300 dpi or 360 if you are printing on an Epson...or you let the printer driver uprez. In either case, your image will be uprezed to the dpi required by the printer. Personally, I like to do it as I have control over the uprezzing.

Agreed. Although modern printer drivers, or rather the firmware of the printers, are getting rather good at it.

Kind regards, Wim

That might be true but if you like to sharpen as the last step, well if the printer is resizing then you are not sharpening as the last step.

Some photo printers actually do, especially the large format ones . They not only increment size in steps, as required, but also sharpen. They are really getting very clever these days .

Kind regards, Wim

The thing is the lab I use advised me to do the resizing myself since they said the software/firmware of their printer(s) don't do as good a job, in their opinion.

So we have all heard and/or know that a bigger pixel is a better pixel but at what quantity?

Why not just have a 35mm sensor with a giant Red, Green, and Blue pixel? What would that look like/do? Just be a blur?

Don't know about IQ... but I can bet you you can push it up to ISO 128,000,000 and still be noise free.
