I got a Pentax 8 Mega Pixels Camera. I noticed that the Resolution is constantly 72 Pixels Per Inch regardless of whether I have the Quality Level at the highest or the lowest quality level (goes from 1 Star to 3 Stars) Should I not be getting a higher resolution here?
 
bobbyfowler, you'd need to give out more information :-
pixels per inch - what do you mean by this - pixels on a printed photo, the resolution of the captured photo jpeg?
Assuming you mean pixels printed, 72 pixels per inch in a 6x4 photo is 432x288. which is quite small for a photo jpeg (assuming it's not a cropped extract of the original). Rather than looking at the quality setting, check to see if there's a picture size option in your camera. If that all checks out, check the options you have for extracting the photo files from your camera e.g. raw, jpeg etc. Then check how you're processing them, eg. what software is used to print etc. Failing that, talk to the shop who sold you the camera and get them to demonstrate how it works!
 
I had taken photos indoors with the Pentax & the quality was pretty poor.
I've also got the Nikon D70S. If I open my photos in Adobe Photoshop and check the image size - under the resolution the Nikon has 300 pixels/inch. With the Pentax it's 72 pixels/inch. I'm presuming that the problem is with the resolution - I can't see where I'd change this on the Pentax.

bobbyfowler, you still have not answered the key question asked by aldark above, so let me ask it a different way -
How do you get the images from your camera to your computer?

Or do you use pictbridge (or similar) to print from a memory card plugged into your printer?

or do you use a TWAIN interface to PhotoShop?
 
Sorry lads

I connect the camera via a usb cable to my laptop. I go into explore & right click on the device. I just double click on the folder the photos are in - then I right click & open them up in Adobe Photoshop. I just manipulate them from there. The resolution of the captured photo jpeg on the Nikon is 300 pixels per inch while on the Pentax it's 72 pixels per inch. One thing is that I haven't loaded the software that came with the Pentax - the laptop recognised the device. Should this make a difference?
 
Most cameras by default show the image file at 72 dpi, but the important thing here is the 8 megapixels of information captured in the photograph, you can use software (I use photoshop) to reconfigure the file to show 300 dpi. The amount of information captured before compressed into a jpeg could be between 8mb and 17mb which is important to have the quality in the image.
 
bobbyfowler,
Usually digital cameras have two options affecting picture quality - compression and resolution. Compression will affect the overall quality of the image - this is probably your "stars". Resolution affects the size of the picture - the number of pixels. There must be another option for this in the camera set up - perhaps called picture size - large -> small etc.

I very much doubt that the pentax software would do anything to the picture files in transferring them from the camera to your pc but who knows? Try installing it and see. If you're opening the camera as a share you're using default windows wia drivers, perhaps the pentax drivers are different?

Does the camera's manual have anything to say on these topics?
