DRebel and Image Size

This photo was taken from Brooklyn on May 14. Digital Rebel with 24-

70 L USM f/2.8, 45 mm, ISO 200 at 1/80 sec. Water was blurred in PS

to give longer exposure and shutter speed. I blew it up to 24"x36"

at 200 pixels/inch. Saved in on CD, took it to phoo printers who

produced a nice poster size photo using LightJet Digital Photo

Printer. No pixelization is noticed on the finished product. I

believe I could have gone even bigger, but at the higher cost.

Cheers.

Nice picture, Bajan, but I suppose you knew that or you wouldn't have gotten a 24x36" print made. :)

What did you blow it up with? Did you use anything like Genuine Fractals, etc., or was this just done in PS? If so, was it a one step or multi-step resize?

I do this all the time without up-sampling the file size. I have my converted (and postprocessed) 16-bit raw files printed directly through my imagesetter's rip.

what lense did you use? I can't seem to get sharpness like that with my digital rebel.

I've heard from others that it is best to let your print house do the 'blow up', since they have some very pricey software RIPs to do the work, that put things like PhotoShop's re-sampling or Genuine Fractals to shame...

Sorry to get so late...the lens was EF 24-70 f/2.8 L USM - an excellent, though bit expensive and heavy walk-around lens. I used PhotoShop to resize the document size - basically double the size both in length and width in inches, while increasing resolution from 180 to 200 pixels/inch. I was told by the printers that LightJet printer works well with 200 ppi. I did not check constrain proportions and the resampling was bicubic. I would assume that printers would do this for me at an extra cost.
