Hello!.

My dad has sent me some digital photos, but it seems he hasinadvertently changed settings. I believe his camera is the sonydscp200..

The first picture is:.

Width = 6.827 inchHeight = 5.12 inchResolution = 300 pixels/inch.

The second photo: (Problem!!)Width = 28.44 inchHeight = 21.333 inchResolution = 72 pixels/inch.

I can't get to the camera to see what he has been doing..

What happened to the second photo?.

Any suggestions?.

Ignore it..

Pixels/inch is a printer setting and is pretty much irrelevant even when you print the picture..

As to why it happened. Most cameras send out their pictures with a 72P/I in the EXIF the first picture was probably edited the second not..

A member of the rabble in good standing...

One is optimised for print (300dpi), the other for on screen viewing(72ppi)..

The resolution is unaffected. In photoshop you can change the image dimensions and dpi setting all you want without changing the resolution of the image at all..

The others answered properly already.But I will just add this..

In your question, you omitted to mention how big the image is in terms of pixel dimensions..

The first picture is:.

Width = 6.827 inchHeight = 5.12 inchResolution = 300 pixels/inch.

6.827x300 = 2048 pixels5.12x300 = 1536 pixels.

The second photo: (Problem!!)Width = 28.44 inchHeight = 21.333 inchResolution = 72 pixels/inch.

28.44x72 = 2048 pixels21.333x72 = 1536 pixels.

So the two pictures are identical. Both are 2048 x 1536 pixels. Not a problem. What did he do wrong? Nothing..

As to what happened, possibly a camera setting, but quite possible also some editing program he may have used, perhaps to adjust brightness or colour, may have, as a side effect changed the dpi setting from 300 to 72. But it's easy enough to change it back, if you ever needed to. For on screen viewing it should make no difference, as the image has to be reduced in size to fit on the computer screen which will be (usually!) a lot less than 2048 x 1536 pixels (more commonly 1024 x 768 or some variation).Hope this helps,Peter..

The photos were not editted. It seems like the first photo prints nice and crisp, while the second is blurry and lacks the detail of the first...

The DPI setting in the EXIF header does not affect the image quality in any way shape or form. If the two shots were printed at the same size, on the same paper, with the same printer, then the second one is blurry because it is blurry, not because of the DPI setting..

You can change the DPI settng in PhotoShop (or any other editing software) to 300 DPI if it makes you feel better. It is the number of pixels that matter..
