Default Adobe help. Loss of quality?

Help! I use adobe photo deluxe (home or business ed). Why is it when I open a picture from my cf card, it is automatically sized in at 72 dpi? After I edit, I resize it to 4X6 at 300dpi. But when I print this on my sony ex7 the quality looks less than photos that come straight from my camera without edits. (These prints look GREAT) Is there sampling going on? or Interpolation? Should I leave the large size and 72 dpi alone?

What do I need to do to get the best image ready for my printer?

Thank you and hugs to anyone who can answer this!!!

72 DPI is the resolution of your monitor. Resizing will alter the quality, any interpolation up or down does. Don't resize before printing as you don't need to.

If the image is 1200x1600 when printed to 6x4 it's about 300 DPI anyway.

See how big the image is when viewed 1:1

I still use Adobe Photo Deluxe 1.1 (business ed)
72 dpi is the default setting and is "meaningless", just stick to the absolute pixels size , or always recheck it when you change the dpi setting.

As mentioned before, the 72PPI is the monitor resolution so Adobe defaults to this. It hasn't actually changed the resolution, it has just assumed that you want to change it to 72PPI. Ignore it.

To resize, select 'photo size' & make sure the "file size" option at the bottom is ticked. This will ensure that the total number of pixels from the raw image is retained. That is; it will not resample. If you don't tick it then Adobe will resample. Also ensure 'proportions' is ticked to keep the new size proportional. Now just change the width or height to what you want. If you change one, the other will resize proportionately. When you change the width or height, observe what the resolution changes to. The bigger you resize, the smaller the PPI number becomes. This is ok, but make sure it doesn't drop below about 200PPI. If it does then you are trying to make your image too big for the camera resolution & it will no longer be 'true photo quality'. If you have to make the image so big that the PPI drops much below 200PPI, then you are probably better off resampling. That is: leave 'file size' unticked & type in 200PPI in the resolution field.
happy shooting
