Anyone here use it? I got it because it is free and I like the results but I just noticed that I can only save as jpeg in the free version and that it saves it at 96ppi. Instead of the 250ppi my camera reproduces. I can go in and type the 250ppi back in PS but recently I changed the ppi from 250 to 300 and got some photos rejected because of upsizing... So anyone here use this? and no how to keep your original ppi?

Thanks in advance.

When you save it, and it changes the ppi, does it keep the original dimensions, e.g. 3072 X 2048?? If so, don't fuss about the ppi, or dpi, just look at your pixel count - the other two are 'display' values, and only of concern if you make an image that wasn't big enough into 6 X 4 @ 300dpi in photoshop, which will then interpolate and resize... leading to a d'oh situation...

you know I didn't check to see the dimensions but I will check and see. But wont the ppi matter if it is going to be printed? I'll do one and upload it and see what the reason is given when it gets rejected. Shame too because it does a good job of cleaning up the image without losing alot of sharpness. Thanks for the help.

I've tried all the others, I like Noiseware the best. It's easy, consistent and gives good results without over-doing it.

The size generally stays about the same. You might notice the dimensions get a bit smaller, depending on how much noise it's compressing. It's never been an issue and I can't remember the last time I had a noise rejection or one for over-processing either. It is excellent at retaining detail.

My camera does not produce much noise, so I take whatever default correction amount it comes up with and reduce each value by 20.

The PPI is primarily a display value - most people wanting to print will change it if they need to - but as long as you still have the physical pixels, it's not that important - a 3072 X 2048 picture at 96dpi is still 3072 X 2048 - it'll just display as 32 X 21 inches, the same 3072 X 2048 picture at 300dpi will be 10 X 7... but either will still have 3072 X 2048... like I said, the problem with playing with DPI/PPI stems from having an image that's been resampled to display at a size at a given dpi - if you crop or resize to 6 X 4 at 96ppi, you now only have a 576 X 384 pixel image... fine on a monitor, useless for printing... if you crop or resize to 3072 X 2048 at either 96dpi or 300dpi, the image will stay the same, only the display size will change...
