Large digital print

[david_buck2]

I would like to print large digital prints. In the size of 100cm x

70cm or 40x28 inches. And some of them are cropped prints

 

The photos were shot with Nikon D70 in JPEG/FINE (did not have

NEF:RAW software then) and saved as TIF.

 

1) Is this possible without loosing too much details or having

pixels? If yes - how should one go about doing it?

2) I heard of some software cabaple of doing this; Called

interpolate (??). Any recommendations on software?

3) I use PS CS. Anyway to get large prints from this software?

 

When I resize the image to the large size I want, I see some

pixels. Will it appear on the print in large format?

 

Thanks

Dave

You are leaving us in the dark -- what will be the primary viewing distance of your intended large print?

<p>

PS CS2 has several nice tricks in upscaling images -- it mostly depends on the intended use of your large print. A pixel could be an 1/4 inch across (or say "4 dots per inch") if you will use the image as a billboard where the closest viewer is 50 feet away.

Also, this was answered already recently in this forum,

Find a good pro lab with a Lambda, Lightjet, or Chromira printer. Take them the best files you have. They will show you what they can produce from these files. I wouldn't do any up-rezzing, let the lab do that if necessary. You can have them print a small region of your file at the large size so you can see how it will look without commiting to a large print.

Thanks Ken. Viewing distance is probably about 1metre/3 feet way.

 

Just wondering, if I resize in PS CS in the large size that I want and increase the resolution, does it help?

Apperantely yes, David. It's the new techiniqe in Kelby's CS2 book. Enter your desired up-size in inches and enter 360 dpi. With the bi-cubic choices enter bi-cubic sharper.

 

I've yet to try this becasue the Frontier I've been printing off of lately wont accept a 360 dpi image.

Interpolation refers to applications such as Genuine Fractals...or the perhaps-superior equivalents in CS2 and Qimage (cheap, good).

 

I've seen 3-meter images from 6X7 ...I think Genuine Fractals was used.

 

You do see the interpolation figures that get created to fill in the image, but they're attractive...something like tiles.

I don't know the new technique you're referring to, but did you mean to say

"bicubic smoother", not bicubic sharper? AFAIK, smoother is for going up in

size and sharper is for going down in size.

 

But maybe you really are thinking of a new technique I'm not aware of that

benefits from using bicubic sharper to go up in size?

try useing software by "shortcut"called photozoom pro v1.1.2" it uses a s-spline algorthym which a far superior to the old bicubic way. you will be amazed at the results. no pixilation of any kind up to a huge size
