G2/G3 print size?

[Jim Lewis]

I'm unfamiliar with the term
"step interpolation." Does this mean res-ing it up in steps rather
than all at once? I seem to have better results making the canvas
size bigger, then scaling the image up to fit the new canvas
size...rather than chaning "image size."

Yes, that's exactly what the term means. I picked this up from a British DP publication about eight months ago, but since then have seen it several other places -- and it's a snap to test it yourself to see if you agree with the results. A series of 10% bicubic interpolations produces noticeably better results than one single interpolation. Since it's a repetitive process, you can build an action to accomplish this.

Fred Miranda has done some tweaking of this and built an action that I'm told improves on it, though this is heresay.

And from you, I got the tip on changing canvas size first. Thanks. Gotta give that a try.

Enjoy your G3. If it's as much fun as the G2, you'll have a ball.

4. Finally (and here I'm sure someone might argue) I was routinely
resing up to 300ppi for printing (bicubic; I like it better than
GF). One day I thought I'd try leaving the file unchanged and
printing at 12x16. That gives you 142 ppi. Amazingly I liked the
results better that way! The prints seem sharper and crisper, and I
don't see any pixels without a loupe.

interesting because i usually crop without ressing up and have liked the results too.

question: why do you like bicubic better than genuine fractals? most people don't. also, do you like how your prints look when ressed using qimage?

I use my 2200 for all my printing but I recently had to work with a friend who has an Epson 7600 for a 20x24 print I had sold (a scan from 4x5).
It's really not much fun to have someone else do your prints.

Thanks for sharing John, I've been looking for some Gx user
experiences with printing. I'm very pleased to hear of your
successes in making large prints.

Are the prints you're selling at your gallery professionally
printed? Or from your Epson 2200? Time for me to begin the
printing journey.

most people don't.

I saw some tests (wish I had printed them out so I could cite them) that claimed and showed slightly better resolution through the stair interpolation method than through GF. But I've used both and can't discern a difference using a loupe.

Given that, I suggested stair interpolation to Christopher rather than trying to sell GF.

Most people call it stair interpolation.

Right you are. "Step interpolation" is a term used in scientific computer applications. (You don't want to know.)

hi guys,

you already say that a G2 is great for 8x12 print , is it in raw, or the super fine and large size setting in G2?

please confirm

thanks

I've been seriously considering purchasing a G2 or G3, but have
been a little concerned about maximum print size.

I will want to do large prints (at least 11" x 14") and would love
to go 12" x 18".

Are there any G2/G3 owners with good/bad experiences doing large
prints like this out there?

I'm a graphic designer and am very familiar with file resolution,
etc., but I can't remember the formula for digital prints. I
recently read somewhere that it's 150 pixels per inch @ 100% which
would put the G2/G3 at 11.36" x 15.147"

Does it depend on what kind of printer you're sending the file to?
Inkjet, laser, lightjet, etc.

Any help clearing this issue up would be much appreciated.

Thanks in advance!

Go out and buy Photoshop 7 Artistry by Berry Haynes & Wendy Crumpler. It's the best book money can buy for digital photographers.

As always, just give it a try. If you are not tight on storage you might as well use RAW. BUT, I have often run low on storage on a trip and gone to fine JPEG. Frankly I don't see an appreciable difference. It's nice to have the RAW file on hand to tinker with but you can't do a great deal in the Canon Raw converter anyway. John

Stephen; I just wrote quite a long letter about image enhancement but I think my wireless roadrunner link went of while it was sending. GRRR.
Maybe it will sho up but I don't have time to rewrite now.

... is what most print services use to print....

to print a 12 x 18 you would need (max) 12x300 x 18x300 = 19 Mpixel.

in real life you may get away with less for an acceptable result. You can also extrapolate the photo in photoshop to get pixles and avoid block artifacts. This will still soften the photo still....

I have never printed larger than 4x6 from my G2 ....

I think real experiance is the only measure either from users here or yourself.

I recommend: Dowload on of dpreviews. G3 testphotos and get it printed 12x18 , then decide if you like it.

extrapolate/enlarge the photos or do you get the original size to gfet printed?

I have couple prints sent to Jumbogiant.com and I am very pleased
with the results. Of course, the files were manipulated a little
bit to be able to get it to that size. Before the end of the year,
I will upgrade to G3. My wife just gave me the green light.:=).

I have also printed my own prints on the Epson 780. The largest
that I did was 8x12.

Hi Christopher

An idea if you want larger prints, is to use Genuine Fractals 2.5,
software developed by http://www.lizardtech.com .

An example can be seen in this months Digital Photographer.

It is claimed to resample an image up to 600% of its original size with minimal quality loss.

I alwys get my stuff printed at costco too! I will try the color profile.

Last time I was there I asked the guy how many dpi his machine prints. He claimed it doesnt print dpi .." It works differently" ... the guys there arent too knowledgable

One thing you should know, if you have not yet known, is that you
should use profile for your printer. If you bring to Costco (or
outside for printing), be sure to convert your image to Fuji
Frontier 370 or Fuji Frontier 390 profile. Bring it to Costco, and
tell the operator to "print your images without any color
adjustments". That would produce colors exactly the way they look
on your monitor, provided that your monitor colors are correctly
fine-tuned.

This place will provide you more information about how to get
profile for your printer model.

Chris,

I work for Xerox and as such, have access to their wide range of colour digital printers and copiers.

I am amazed at the output quality of my photographs when printed on these machines.

I constantly print my photographs at A3 size (297mm x 420mm or 11.68" x 16.53") and there is never any noticeable pixelation or degradation in the finished product.

All my shots are taken at 2272 x 1704 resolution, Large - I haven't tried RAW format yet

Soon, I intend to conduct a series of 'similar' photographs (using the same subject and lighting) at the different resolutions and compressions. I want to see what differences are visible once the photographs are printed.
