saving a high resolution png in Photoshop CS6

[socahweir]

I just installed CS6 and am trying to save a high resolution PNG in Photoshop. When I go to File > Save As there is no longer a PNG option available. How do I save a high resolution png?

thanks

What do you mean by "high resolution"?  Is it possible you're confusing pixel count with high bit depth?

Are you trying to somehow save a 16 bits/channel document in a PNG?

As far as I know Photoshop can only save an 8 bits/channel document as a PNG. 

Some formats, such as JPEG, will automatically do the downconversion for you, but not PNG.  Use Image - Mode - 8 bits/channel to get there from here.

Save As PNG will save 16-bit and 8-bit PNG.

Save For Web PNG will save 8-bit only.

Oops, wow, I really need to check my facts before posting.  I confused that with another format I guess.

Thank you for the correction, Conroy!  I learned something new.

Are you sure that Photoshop is in RGB or Grayscale, and 16-bit or 8-bit?

When I switched the file to RGB, the PNG option came back in the Save As section. Thanks for the tip.
