Crop it.

The width-to-height ratio of the images your camera produces is 3:2. So if you print a photo 11 inch long, it will be 11 x 2/3 = 7.33 inches wide.

If you want another width-to-height ratio, the only thing you can do is crop to make the ratio what you want.

hmmm.. i don't think i can crop bec for the mark 2N i think the maximum output in 300dpi tiff from a basic raw image is only 11x7 something inches, the one i need is 11x8 or more (8x11 on some)

I think that you need to learn some more about post-processing and resizing files.
The output from the camera is just a start, you can set any size of print you want and any resolution in Photoshop (or similar) and the program will do the up/down sizing needed - or there are other programs to do this - look under 'image size' on the Image menu in Photoshop and play about with the settings to see how the relationships change.
Do you need 300dpi exactly? What are you outputting to? Answers to these questions will affect how you need to go about processing your image.

RawShooter Premium has a pretty nice uprez algorithm, IMO. It will allow you go to up to 300% of your original file with quite good results.

I am constantly amazed at the amount of professional (or otherwise) photographers with amazing digital kits who don't know how to perform the most simple of digital post processing tasks.

Given that the offending post has been quoted twice now I won't go through the steps of deleting it...
I'd only like to remind the less helpfull members here of the forum rules (http://photography-on-the.net/forum/rules.php)
... in particular Section 4-9:
If you know an answer to a question either answer it or say nothing. Giving newbies blunt answers like "search the forum" is not allowed - please use the typing effort to giving the answer instead. Or just give the link to that post you wished the newbie should have searched for. Respect newbies - you were a newbie once.
This rule in particular is the cornerstone of this forums atmosphere and freindliness. There are dozens of other photo-forums out there where one can go to ignore such pleasantries. Please don't do so here.

Kriskent,
The MkII N's 8.2 MP files print very well up to and larger than 13"x19" so don't worry so much about 300dpi. (I find 200 DPI stunning and often print at lower)

I'd first recomend you try printing at a lower DPI to achieve the larger dimensions,.
But if you absolutely must print at 300DPI use Photoshops image size features to "up res" or "interpolate" your images to the dimensions and DPI you require.

As mentioned above,. you can use your RAW converter to output a larger file size as well.

Was I too blunt CDS? Didn't mean to be...

I know that my photoshop skills aren't the best and perhaps I have done it wrong but I simply put the image size that I wanted in the crop tool boxes.

I have printed up to 30X40 from the 1DMKII and the final prints have been very good.


I has taken some playing around with the DPI to get the right value based on the image dimensions.

I apologise if my post has provoked any sort of offense, that was not the intention. My reaction was bewilderment, pure and simple.

As for insinuating that I am an unhelpful member, I think that is very unfair comment considering the lengths I have gone to to aid fellow shooters in the short time I have been a member here.

To the original thread poster - sorry if my comment was hurtful. It wasn't really directed at you, more of a general sweeping statement, but I admit it was neither the time nor place to make it. It was late and I was tired. By the looks of your gear list you have made a significant financial investment into professional photography equipment, I suggest you extend you budget a little further and purchase some quality literature on the post processing subject.

Nope, not you. The one that made a comment about you not knowing what you were doing was the one he was warning. Basically, ignore dpi. Its just a number put there to trick you (not really, but imagine).

What you want to do is in photoshop, go to view-> print size. This will show you how your image will blow up.

Using the crop tool is a pain because it tends to resample the image - as Sheldon says, you have to hunt for the right resolution value. It's easier to use the rectangular marquee tool (the top left one in the toolbox) - set it to fixed aspect ratio, then, on the menus, Image -> Crop.

The use of paths to store crops that I describe here (http://photography-on-the.net/forum/showthread.php?p=1454189#post1454189) is a neat way to store crops in Photoshop files. The description there is rather terse - let me know if you want it expanded.

Guys this is the thikrd post today that I have noted there is a big difference between ppi - pixels per inch and dpi - dots per inch and they should not be confused.

your image is sized at ppi and optimum is quoted at 300ppi for printing. You can print lower without really seeing much difference.

dpi is what a printer's resoulution prints at. For example 1440x720dpi

Remember when dealing with image resolution it's pixels that are important (not dots)

You can crop from RawShooter Premium and choose your resolution output before converting. That's what I was recommending, although didn't do a very good job of specifying what I meant.

You can also crop in Photoshop without resampling. Select the crop tool and enter the size of crop you want (11in x 8in)in the bar at the top. Leave resolution blank.

This will crop without resampling. you can then check the ppi count going to Image>Image Size and resmaple from there if you need to.
