Title: Large print Post by: piyush on April 14, 2009, 11:48:19 PM I am using 10 MP Canon 400D camera and in one of the assignment, I will have to get 20 inch X 30 inch print. I tried it but print doesnt look good. Can somebody throw some light on how to do that? I am using Canon DPP and Photoshop. Do we have any special operation/workflow/settings/software to get better image quality for this size?
Title: Re: Large print Post by: Bob Atkins on April 15, 2009, 09:46:52 AM You will get the best image quality with the camera mounted on a tripod, ISO set to 100 and the lens stopped down a little. For slow consumer lenses I'd use f8, for faster "L" series lenses I'd use f5.6.
Other than that, it's a matter of using an appropriate degree of sharpening before printing, as well as adjusting color, saturation and contrast to give the best visual results.

What are you printing on? Here are some tips: Start with the sharpest image possible. In photoshop use the image->resize command to increase the number of pixels in the image. Resize in small increments - about 20% per step. So if you are starting at about 4000 pixels on the long side, increase it to 4800 -> 5700->6800->7200. Remember, too, a 20x30 inch print is not meant to be viewed from inches away! Step back to about 4-5 feet to judge the print.

Title: Re: Large print Post by: piyush on April 16, 2009, 12:30:45 AM Bob, Keith, Thanks for the input. I will try doing that again.
By the way, That print will be on a wall so will be atleast at 5 feet of viewing distance. |
