resolution for camera setting

[HunnyB Profile Private message]

I thought I had everything set on the highest res.
But today I looked at some pics I took and the res. is only 72.
The size of the image is 4752x3168 and 3.98mb and 5.65mb.
Shouldn't the resolution be higher? Or does it matter.

Hunny:

72 is referring to the DPI. The default DPI your camera uses will have no influence on the resolution of your images because it only relates pixels to absolute units (inches). The DPI setting therefore does not affect anything when displaying the photo on your screen, the web, via email, etc. To be honest, the only time it will matter is if you are not setting the print size of your images prior to printing. Setting the print size always overrides the embedded DPI.

Just ignore it and enjoy!

Hunny: Only the total pixel size (4752x3168) counts, you are at the highest resolution! The JPG-size varies according to the amount of detail in the image (like your 3.98mb and 5.65mb).
Many cameras output their images at a resolution of 72 pixels per inch, the standard resolution for screens. As long as you work with some sort of image processing software this doesn't matter, since physical size and resolution are always adjusted there. But actually, I don't know if one can force cameras to output images at a higher "pixel packing rate" per inch (ppi resolution), maybe somebody else has an answer there. But then again: this should never be important as long as you work with software and not want to print out images directly from the camera.

I see that Mike was first to answer, I think he says pretty much the same. His DPI is the same as my ppi, Dots per inch as compared to ppi, pixels per inch. In Europe we use ppi.
Good luck!

Actually, I think the correct usage of DPI vs PPI is that DPI is dots per inch and refers to printer output. PPI is pixels per inch and refers to monitor/screen dimensions. So those Europeans (darn it) are right again.

They're easy to confuse and most folks will know what you mean whether you say DPI or PPI especially since we talk about cameras a lot more than we do about printers.

PS Happy New Year one and all.

Exactly what they said. When you take it into Photoshop just change to 300 and your prints will be great!!

Thanks, Joe, for the clarification regarding DPI-ppi. The credit to Europe is largely undeserved though, since both standards are originally rooted in North America. The competing European standard was ppcm, pixels per cm, and that one never caught on here, even though everything is measured in centimeters (or meters) otherwise

Thanks guys. I guess I was thinking back to my printing days and how important the resolution was.
I feel so much better now after ya'll explained it to me. I took some pictures today and plan to do a show tomorrow. I hope I can post it real soon. THANKS AGAIN!!
