I've just done 2 pretty important shoot for a college project and I used the Canon 5D mark II - Im a nikon person so I didn't really know what I was doing.

The pictures came out really well ( not printed yet)

AND

somehow they are all 72ppi !

Yes I shot on jpg but a large non compressed jpg

What can I do?!

Any help is much appreciated!
 
72 ppi at what size? I think 72ppi is the default (vaguely though) but the sides of a full size jpeg should be really really long
 
Guys just to make you happy, that number means nothing. The only thing that matters is the total number of pixels.

In a digital image the ppi value sets the print size nothing else. So at 72ppi the image would be MASSIVE and at 300ppi the image would be much smaller.

On a 5D MkII you have 5616 x 3744 pixels.

At 72ppi the printed image would be 78" x 52". Rarely do you want to print at 72ppi though. In Ps you set the ppi ONLY when you are ready to print. If you change that to 300ppi the print size would be 18.72" x 12.48".

Both the 72ppi image and 300ppi image are the same image - nothing different except the actual printed image size.

So forget the ppi value until you want to print and use that to control your output. The only thing that matters is the overall number of actual pixels.
 
I think was at Large non compressed jpg. All sides are 72ppi.

IM SO CONFUSED!

The sides of full size jpg from a 5D are long because of the number of pixels compared to the resolution of your monitor. THe image is 5616 on the longest edge. If your screen is 1600 x 1050 (pretty common now) then the jpg image will be over 3x the width of your screen resolution! Obviously over 5x the height for a portrait image.

This just tells us it's a very large image. It has nothing to do with the ppi value at all. Set the ppi to 300 or 3000 and the resolution of the image itself stays the same (unless you interpolate - which you don't want to do)
 
Guys what can i do to possibly print A3 size,is it still possible?
 
I have done that now when pull post production has been taken and ready for print. It then says " writing to jpg format which takes 2mins,then when i open to preview in windows preview it takes forever to open! Hopefully there will be no problem at Loxleys
 
First of all I would think that everything is going to be OK. I've had quality A3 prints from cameras who's file size is much smaller than those from the 5Dll.

As for the 72dpi, it's something a lot of people get hung up about. It's just a guide, nothing else it has no effect on the image file what so ever. Don't know what your computer is but it does seem slow, it may be short of RAM and is using the hard disk to help out that's why it's slow.

Loxley's should be able to handle things for you. If in doubt have a word with them before you get the file printed

A3 is 297mm x 420mm. (11.7" x 16.5")

Go to the crop tool and enter the dimensions in the width/height box. In the ppi box I'd leave blank.

Crop over the whole image and press enter.

Now look at the ppi in the image size pallet. With 5616 x 3744 pixels the print size is now 297mm x 420mm @ 320ppi.

So the 5D can print A3 without any interpolation.
