What resolution do I need to set my camera at to acheive a 300 dpi or
equivilent photo.

First you need to give us some details.
What camera do you have, how big the print must be and what is the dimension in
pixels of your stored digital image.
If you check the size of the image in your editing program you should see the
pixel count.

For a size of approximately 8x10 you need
about 3000x2250 pixels.

This is all wrong! When I tell people I need a photo I tell them the number
of pixels I want because I know I know more about it than they.

If I need a 2 column photo I ask for at least 600 pixels. That is the same
thing and they don't have to figure it out. Since we publish on newsprint
300 is more than I need....but it lets me crop a bit if I want. Oh....and if
its not being sent by email....send the whole file....I can crop better than
they too!

Answer depends on TWO requirements.

Requirement 1 (given): They want 300 dots per inch (dpi).

Requirement 2 is not given (and you must ask your company for this
detail):
what is the actual physical size of the printed image they want? Suppose
they say 6" by 4 ".

So on the 6" length side, they want 6*300 = 1800 dots. On the 4" width
side
they want 4*300= 1200 dots.

Hence your camera needs to provide them at least 1800*1200 pixels, i.e.
1.92
MPixels. So any resolution of 2MPixels or more will satisfy their
requirement.

You should now be able to work this out for any image size.

Secondly, printers use 1280 dpi or higher for their color seps/plates.

Whoa! OP did not say the request was by the printing company. And....just
because a pre-press department outputs to 1280 dpi going to film doesn't
mean they need that going in. This is because the terminology is all mixed
up.....and its too early to work it out as I have yet to visit the coffee
house....but here is a bit about it....

Cameras take pixels....there is no ppi as there is no i
Image editors let you define the i and change the ppi
Output devices, monitors, printers, film outputers, etc. out put
dots....lots of these dots are put together to form each pixel.
(here it gets messy)
And when its printed commercially there is another use of the "dot"
term....its half-toning. For newspaper it works like this...

The press lays down spots of ink. Up close you can see them but step back
and they blend. 85 lines of dots are OK for newspaper work. To get them on
the printing plate you use a sheet of film (direct processes are available
but film is still used a lot). The machine that puts the half-tone dots on
the plate outputs that at 1280 dpi....but that is a different dpi than the
dpi that is on the plate.

My head is spinning....in a nutshell its because different disciplines used
the term DPI in different ways....and now we have to communicate with each
other.

Monte I have been asked to send a photo to a company for printing. They
Monte want it at 300 dpi and I am not sure how to achieve this.

Oh geez. Another company saying "300 dpi" without a clue.

DIGITAL IMAGES ARE NOT "dpi". Pixels do *not* have a size.
