peng_kit_wong Posted May 2, 2006 Share Posted May 2, 2006 I will be making posters size 51.5cmx72.8cm (20'x30') from EOS30D. I was wondering if 8.2 megapixel will make a good print this size?Also how huge/big can I enlarge from a 8.2 megapixel file? Please advice.

phule Posted May 2, 2006 Share Posted May 2, 2006 You can make it as big as you want. It all depends on the viewing distance. Link to comment Share on other sites More sharing options...
KenPapai Posted May 2, 2006 Share Posted May 2, 2006 This is a very common topic in Digital Darkroom forum. And like what was answered, it all depends on the viewing distance whether you need to "Up Size" your original 8MP image file or not to print at 20x30 inches. However it's relatively routine to do so and unless you have a large format printer you obviously farm out these sorts of jobs. Link to comment Share on other sites More sharing options...
jmf Posted May 2, 2006 Share Posted May 2, 2006 The lab may do this for you, but you may want to try out PhotoZoomPro http://www.benvista.com/main/content/content.php?page=ourproducts§ion=photozoompro_1 or Genuine Fractals http://www.ononesoftware.com/detail.php?prodLine_id=2 Link to comment Share on other sites More sharing options...
austinphoto Posted May 2, 2006 Share Posted May 2, 2006 You should have no problems making a 20x30 from you 8 mp file. Try Austin photo http://www.greatlab.com. $22 for a 20x30. Link to comment Share on other sites More sharing options...

ira_wunder Posted May 3, 2006 Share Posted May 3, 2006 As a proffesional custom and exhibiton lab owner who can't spell, I have some questions and advise. Question, is your file 8.2 megs or are you asking if your camera having a 8.2 meg chip is capable of an enlargement that size. I believe the camera produces a 27 meg file which is certainly good enough. If you have a 24" wide printer or larger and are doing it yourself and do not have a RIP program for it, then use a program as stated like Geniune Fractiles. If you are going to a pro lab there is no reason to res it up to size unless your are going to use a econo lab that specifies you do all the work. The RIP systems that pro labs use can res the image up directly to the printer and does a much better job then PS or the software mentioned. Just a note, a pro lab that will charge more then $22 for a 20x30 but will do much more work on the print, such as noise reduction, zonal changes, spoting if needed. Meaning they will work on it as opposed to just sending it to the printer. Take note that for best results shoot RAW and keep the file in 16 bit, 300 ppi at an un-interpolated size. The other thing I will say for the deep discounted print is make sure the output is at least 1440 DPI. Link to comment Share on other sites More sharing options...
