I know we have a lot of camera and computer savvey people on AZ. I'm not one of them.
I want to send a photo to my publisher for the cover of my next book. She says it needs to be 300 dpi minimum TIFF. How do I know how many dpi my photo is. Thank you. Johnnyt:o
 
Do you have a photo editing software program?

In Photoshop, you'd click "image" and then "size".

Under "document size", you'll see pixels per inch. This is your resolution.

You can go down, but not up. You would need a photo with greater resolution than 300 DPI in order to get this many.

Thank you Mr. Wilson. I have photoshop. Thanks everyone. Johnnyt
 
Hi Johnny:
dpi stands for "dots per inch". It is more of printer term. It's pretty much the same as "pixel per inch" for the display screen.

If you have a 4" x 5" photo at 300 dpi, then the pixel size for it would be 1200 x 1500.

Hope this helps.

You can go up in dpi

There is software specifically designed for resizing images to higher dpi. Genuine Fractals being one such application. Of course, you can't add information to an image that isn't there to start with, but you can resample the image to a higher dpi. I've never used the program, but it was described to me by Tom Shaw, managing editor of Pool & Billiards magazine. The software works as a plug-in for Photoshop or Photoshop Elements. Here's a link to the GF site: http://www.ononesoftware.com/detail.php?prodLine_id=2

And a link to a review. (This review is of an older version of the program.): http://graphicssoft.about.com/od/resolution/a/genuinefractals.htm

All this having been said, if the original image just doesn't have close to the requested 300 dpi resolution, it probably won't look that great on the cover of a book.
 
no tiff has DPI

As others have mentioned the image size is in PPI, pixels per inch. DPI is the print standard, dots per inch. They do translate but the question is 300 DPI at what size? 300DPI at 2x2.5 inches would look like crap on a book cover. On the other hand, all of the photographs you see on billboards have been upsampled as have many of the images you see in magazines. Also prints can look very acceptable around 200 DPI with 300 DPI considered the very best quality the human eye can see.

If you have Photoshop CS, create an action to upsample ten percent at a time or less. Upsample to the size desired and see what you have. All upsizing programs resample the image and add material in to reach the hard lines of color change. Photoshop CS is claimed to be the equal of any.

If you can reshoot, many cameras are available that can shoot at adequate resolution to begin with for under $1000, some under five hundred I believe.

I might just just use a picture of a piece of pool chalk and the tip (1st 5" of a cue.) Title is Chalk It Up For Murder. I should be able to find that on the net. Thank you all. Johnnyt.
 
Just don't use an OB-1 ferrule!

If you use an OB-1 shaft for your pic, people are going to really wonder about that ferrule.
 
OB-1 ferrule

Here's a pic of the ferrule end of an OB-1 shaft. It uses a very unusual wood ferrule. Most people haven't seen one and would wonder what was up.

I've never seen one I don't think, but I use to drink a lot.:D Johnnyt
 
300 dpi is (or at least, was for a long time) the de-facto standard resolution for print work. I used to be in the advertising industry, doing production work, "going to Lino" etc etc.

Now the trick is, you'll want to send your photograph at, or a bit bigger than, the size you intend it to be printed at, *while also at that 300 pixels-per-inch resolution*.

Like Mr. Wilson said, you can reduce the size/resolution of a photo without any worries (it'll just toss out any extra data it doesn't need). He also said you can't increase the resolution - ehh, sorta. You CAN but it'll look like you did - Photoshop won't magically smooth things out for you. Increase it enough and you'll see the obvious jaggy bits. And no one likes that. :0
