The trick?: How do I get 1 to 1 ratio in an image

I would like to photograph a 6" by 8" item and print it so that the measurement is the same size.

Use a close enough focusing lens so that the image fills the viewfinder and print it at 6" x 8" on 8 1/2' x 11" paper, then cut out the print. Done and done.

Fantastic. Thanks! I will see if I can fill the frame with my lens and keep it all in focus.

Anytime.
Good luck

What is the shape of your 6x8-inch subject? Is it flat like a painting, or does it have detail & depth, like a camera body?
True macro lenses are designed to capture a flat-field subject; standard lenses have a curved-field of focus, which is why they often leave the corners out-of-focus when photographing a newspaper or a painting.
Aperture will determine Depth of Field, which will be quite narrow at close range. A long lens at closest focusing distance can provide a deeper DoF than a short focal length lens, whether macro or standard.

Hi Nikonain72
Thanks for your reponse and input.
It's a stuffed toy and I need to print it on a 8.5 X 11. I'm using a 24mm to 135mm Tamaron Lens.
The edges probably won't be an issue.
I will also try my 70mm to 200mm lens as well to see what it will do.

You must realize that a 3 dimensional object can not be reproduced in a photograph exactly life size. Only 1 plane that intersect the subject can be made the same size. Anything in front will be bigger and anything behind this plane will be smaller than life size. Using a long lens and taking the picture at a long distance will minimize this effect.

Careful if your camera is 2:3 and you fill the frame and then try to print what is not 2:3(8x10) or it will get cropped. Think about say 8x12( or the 2:3 proportion) and if you fill the fame side to side, nothing gets cropped.

Have a ruler in the picture, but out of the way. Use a long focal length lens as reasonable. When printing, adjust the image so the ruler is the correct length. Then for the final image, crop out the ruler and print at the 'same' size.

You don't have to fill the frame to do this. Chances are 6 X 8 may not not be the same as dimensions as your sensor is. Photograph it as close as your lens will get and then just crop it in software to the 6 X 8 and print it accordingly.

Why photograph it close? As written before, the person wants a true to life size photograph and only one plane (perpendicular to the shooting axis) can be true to size, and to minimize the size change (close larger and far smaller), as written before, a telephoto lens will minimize this distortion. Exact 6x8 print is not important, matching the items dimensions as true as possible is the goal.

He was asking to get the photo sized as he wanted with no details as to what he was shooting. A generic question can only get a generic answer. I cannot make assumptions and then steer someone down a wrong path as so many do.

Thank you everyone who responded. I will try each suggestion. For those of you who have not tried to produce an image of an object that will fit on a 8.5 X 11 sheet and photograph it then print it on a 8.5"x 11" so that it's the exact measurement of the object (1 for 1), You may find it more of a challenge then you might of imagined. My item is a stuffed animal.
