Hi Guys
Would somebody help please
I am new in digital printing . Preparing an exhibition .
I am going to print on Epson 11880 . Paper is Hahnemuhle Photo Rag Ultra Smooth
Now , the files are coming from Nikon D200 ( 10MP ) but I want to go HUGE
The prints are going to be 130 cm X 90 cm about .
Do I prepare them in 300 ppi or 150 ppi . In both cases I resize ( interpolate ) or what ?
Any other advice is welcome to
Thank you
Milan

Send from 180ppi to 480 ppi to the Epson and let it do the rest. Take the number of pixels you have and divide by 180ppi, that's the biggest size you can print native rez (of course you can interpolate up, point is, use that 180ppi as the lowest value advised to send to such a printer).

Do you mind my asking what kind of tone you are using on this shot. It's very nice.

I used LightZone software . Under Toning go to Brown Yellow and than play with opacity

Milan,
Bring down the image to 180 ppi and then interpolate to what you need with bicubic smoother. Photorag (and cotton papers in general) is (are)very forgiving, I wouldn't worry about it too much. If any doubt, just make a small 20x30 crop and sent it to the epson and see what happens. Not satisfied? try to add some grain.
No plugins needed (maybe photokit sharpener, otherwise use standard PS smart sharpen and Ps grain filters). Really, with rag papers and big print size (viewing distance) 180 is all you need.

hi,
Scott Kelby in his book 'the photoshop cs2 book for digital photographers' in his article 'rule breaking resizing for poster size prints' recommend entering the new sizes in the image size dialog option in photoshop. Change resolution to 360 and use bicubic sharper.
It works for me and I have had good results with my z2100 printer. file size could increase dramatically and i have had tiff files of over a gig in size!
By the way, the background looks very much like the mountains as seen from Clifton beach!
Regards, Ivan

Milan,
Buy Qimage if you use Windows and read Mike Chaney's articles here:
[a href=\"http://www.steves-digicams.com/techcorner/tc_index.html]http://www.steves-digicams.com/techcorner/tc_index.html[/url]
Not just for good upsampling but also for good downsampling which becomes an issue as well with increased camera MPs.

You got it !
It is twelve apostles
I know about Vincent Versace technique .
Is it better than bic. smoother ?
Thanks

Exactly (despite what Scott says). Set the rez to 180ppi as a minimum, then see where the OUTPUT SIZE falls. If its larger than you need, alter the resolution higher (above 180) to hit the output size you need OR if its not large enough, then check the resample check box (give Photoshop permission to add or remove pixels), leaving the resolution at 180, add pixels to get the size you wish.
Doing this from above 180 buys you nothing but more interpolation (which buys you nothing).
Keep 180 as the minimum resolution for this device. Create or remove pixels IF necessary to get the size you wish. If you have enough pixels, the range of 180-480 is what you send the printer to get the output size you wish.

Andrew
Would you please forgive my ignorance
Is it like this :
My file is 27cm X 41cm @ 240ppi ( approximately )
then I crop to 27cm X 35cm @240 then I uncheck resample and type 180ppi
This take my file to 36cm X 46cm @180ppi
I check resample box and type 130cm in to my longer side of the image and I get what I want which is 130cm X 100cm @ 180ppi
This I do with BICUBIC SMOOTHER
The rest I do when connected with the Epson 11880 ( 180-480 )
Have in mind that I am doing it for the first time
Thank you
Milan

You don't need to resample IF indeed what you're saying above is correct (I get what I want which is 130cm x 100cm).
IF at 180 or above, you can get the size you wish without resampling, do that.
In Image Size, deselect the Resample check box, enter the value for width and height you wish. IF it falls within 180-480, that's it, you're done. If not, you need to resample.

When I do that : deselect Resample check box and type 130x100cm I get only 65ppi

OK so you now do need to resample from 65 to 180 (but more buys you nothing).
You need to invent (make up) 115 pixels per inch for the minimum output rez to this printer. Adding any more than 115 buys you nothing. Again, you want the size upon output you desire and need it to fall within 180-480.

Absoulutely. If you do a lot of this upsampling, use Q-Image not Photoshop. Photoshop is a poor substitute.
Also the notion that you could upsample any file with pixels appropriate for an 11x14 print and take that to 40x60 inches without loosing significant resolution is absurd. It all depends on what you are shooting and how sharp you need it to be. You are going to loose sharpness and that is a fact. Yea, you see the big print at a greater distance (maybe) but that is a lot of faking of pixels and a lot of manufactured information, no matter how good the original info is and how you do it. That is why drum scans are vastly superior to any 35mm dslr in this size range. Vastly superior if done correctly and avoiding a lot of dslr noise along the way.

I've recently got Qimage and am very pleased.

In the end your going to have to judge for yourself. Qimage, and the host of other resizing packages do a good job although I would be hard pressed to admit that they do anything more than a subtly better job than PS bicubic. The other issue. as far as resizing goes, is that you will probably want to do a last round of sharpening at the final output size, so the difference between resizing to 150ppi, 180ppi, and 300ppi may not make much difference in how the printed piece will look, it will however affect you sharpening technique and processing time. I hate these discussion about what will and will not work because most peoples assumptions are influenced by their particular taste and the type of work they do. I've seen 3mp digicams produce wonderful 24X36 (really!) and 10mp cameras fail at producing a quality 16X20. So my only advise is to listen to the above suggestions and make a few test prints at full size, it's an expense, but it's better to waste a bit of paper with experimenting in the beginning before knocking out your whole portfolio.
