need help calculating pixels for contest

I want to enter a photo contest, but here is my question: they want to be able to print the photos at 300 dpi 13x19 (my guess is because that is how big the sponsor's new printer can print! ) Well, my thinking is that I'd need to have a 22+mp camera because:
13x19 @300 = 3900x5700 = 22,230,000 pixels!
Is that how it is calculated? Can someone help, or point me to an article that I can read?
thanks so much you guys!
p.s. my avatar is what I would enter

I would have used the same numbers and got the same answer.
I don't know if that is the right formula.....
Someone will jump in here and confirm or correct the numbers.
Like your avatar!!!
Question for you:
Do you take a lot of horse and horse rider images? If so, can you post some? Website?
Looking for ideas!..
Thanks,
Pat

Pat - I love horses & I'm owned by 2 of them. So I do take a lot of photos of horses, riders, and anything to do with them. But I don't have a website....at least not yet. :-)

Snowbear thank you sooooo much! :-)
Just upsize the image to 13x19 at 300PPI. Software will manufacture the additional pixels. Works great. All the table that tell you how many megapixels you need ignore how good the software is at making enlargements.
One note in Snowbear's link addresses that: "If you know how to use image editing software like Photoshop, you can "cheat" even more by increasing the image size, and even doubling the number of pixels in the image. The quality of the camera and lense becomes more important at this point bacause any loss of detail or sharpness is magnified. If an image is enlarged too much in this manner, it will look "fuzzy" or "pixelated"."
If upsizing in PhotoShop, doing it in small steps, about 10% per step, will result in better results than doing it in one step. It's call "stair interpolation".

Thanks guys, but I don't have PhotoSop, just Elements 6. :-(
You can upsize using stair interpolation in Elements just as easily as in PhotoShop.

I would ask for clarification on this. It would probably be fine to send them un-cropped images from any modern DSLR. The Nature Center near by does an annual calendar and they want images that can be printed at 300ppi too but what they really want is an uncropped image that they can, and will, PP to fit the calendar. I know guys that hate the way they PP (post process) the images for the calendar.

well, to be very open about this....I already had sent the un-cropped image.....and....
I just found out this morning that it was selected as one of the finalists! I guess they didn't care afterall. The reception is this Friday night (the 13th lol) and the results will be announced then. I'll let you all know.
:-)
Congratulations. :thumbup:
Best of luck on Friday. Please let us know how you did
I didn't think they'd be that picky. They can take a full sized uncropped image and print it to those sizes easy.

I'm jealous. I've never had a picture published in paper. I read in UHH all about these great shots that get printed in magazines, or in phone books or calenders...anything permanent. The closest I've come was Picture of the Week in and online aviation newsletter (my avatar). I probably need a better camera or better glass, or some formal education on how to get prize-winning shots. What makes a good photograph anyways? Is is all just subjective, or is it mostly a technical thing? Congratulations on getting into the finals.
