hi everyone,

I took a portrait of doctors today and was asked to provide a print to fit their frame in their office which is sized 11"x18". I used my 1000D (RAW) which is a 10MP camera which at 300dpi equals about 10" without resizing.

I would like to ask everyone here how they increase the size to A3 so I can print with good quality. Here are my more specific questions:

1) I use Lightroom. Has anyone tried exporting large sized prints in Lightroom? How are the results?

2) If Lightroom isn't the best tool for this, does the 105% upsize in PS work well for these sizes? (I read about this before but haven't tried it.)

3) Or can anyone suggest their own tried and tested way?

This is my first time to print at this size so I am hoping to learn from everyone here before I print.

Thanks in advance for the help.

You can upsize your RAW file to produce a print roughly as big as 13"x20" at 300ppi during RAW post processing and conversion.

You won't have to use any interpolation software (i.e. Genuine Fractals) or the step method (i.e. 105% increments).

Cheers!

Thanks Mr. Avila.

hi brian,

i just want to add that 11x18 is a non-standard size. the closest paper size printers use is 12x18. just use that as your reference when sizing your file for print........might have to black-out the sides to compensate for the difference and just have your framer cut it out.

just thought i'd mention it. good luck!

hi brian,

i just want to add that 11x14 is a non-standard size. the closest paper size printers use is 12x18. just use that as your reference when sizing your file for print........might have to black-out the sides to compensate for the difference and just have your framer cut it out.

The closest size is a custom size that is called 10R (10"x15"). It's a paper size that is offered by some photo labs. It's also directly proportional to the 2:3 ratio of the digital images produced by our digital SLRs.

I'll make this easy. Your 10 mp camera has plenty enough resolution to print 11 x 18 so you don't have to mess with any uprezzing or interpolating. Crop your photo to 11 x 18 and send it to the printer to print on 12 x 18. You will need to trim your photo after but that is the easy part.

Had a number of 12 x 18 portrait prints of my wife and kids made, taken by my Canon 300D (6MP) camera. The print resolution (both on glossy and matte paper) is very good.

hi Rey,

Thanks for the input. The real reason I am printing to 11"x18" is that it is the closest size offered by the print lab I am using to the frame the recipients want to use.

I appreciate the input as always.

@Jo, Nick, and Jon: Thanks for the additional information.

Thanks again,

Brian
