Hey All,

So for the last few weeks, my cameras full quality shots are giving me 17x11 from the camera. I tryed to re-set everything, but it didnt work. I shoot in adobe RGB, not sRGB, and I am thinking that could be the issue. I need to know why my shots are not the normal 48x36 out of camera.

Thanks so much for your help, I have short track racing to shoot tonight, so a qucik response in appreciated.

How many pixels are you talking about? The final print size isn't the same as the number of pixels.

I think you worry about having 72 dpi instead of 300 dpi in image data. Dpi does not mean anything. Just make sure the file format is correct in camera and you get all the X*Y pixels out of it. Color space is not relevant here.

Bring what back to normal? Just shoot at the highest resolution that the camera is capable of and as Pekka said don't worry about the dpi in the image data since it doesn't matter.

just resize in PS without resampling...

but i would say you've probably misunderstood resolution a little though.

perhaps you've changed the ppi in raw from 72 to 200? if you do the maths... 3405x2336 = roughly 11x17 at 200dpi = roughly 48 x 36 at 72 dpi

you havent lost any pixels, you just have more or less per inch...so the size changes.

to be honest 72dpi is a pretty pants res for printing, but if your printing 48" then i guess people wont get that close, and perhaps the output method masks it a little...

Well I shot the Edmonton GP, I have posters printed from the event, and out of camera they were 48.99999 inches, by 36.999999 inches, which makes for easy process and ripping for the printer. Now, to get a 24x30 poster I have to enlarge which is not easy to do, with loss of quality and whatnot.

So? There is something wrong.

In Photoshop's "Image Size" dialog:
Untick (i.e. deselect) "Resample Image" selection and then type in the "Resolution" what you want.

Ok, I havent shot raw since it happened, but can you tell me how to get that back to 72. Its just easier if things stay the same on me, and dont change around.

I do understand the whole res = size deal, its just I have been printing posters from that event for a while, and i have the poster workflow down pat, and now suddenly its gone, that resolution deal just messed me up. So all I need to know now is how to get the camera to import the image as 72, and not 200

depends on the raw converter, but in acr its at the bottom of the window. It wont upres (ie pump more pixels in)...you already have them there, but it will just change the res to size ratio to something your more accustomed to.

ah...sorry...misunders​tood.

Have you changed image import method (e.g. straight from camera vs. card reader)? The image exif in camera do not change accidentally and there is no dpi setting in EOS, only explanation can be that exif changes in you workflow or some updated software or changed software settings does it automatically.

The big question is: what has changed in your workflow?

if you cant suss it, record an action in PS...image size with resample off to 72 dpi...batch the images beforehand.

Honestly, it seems pretty irrelevant to me. I would just set my crop tool to the dimensions I want and call it good. What size PS tells you the print is doesn't matter at all. You define that yourself when you go to print/upsize/whatever.
