    I thought you'd be able to get much bigger with 8MP :confused:

    I've printed 30x40 with absolutly NO problems with a 10mp camera.

    That chart must have been made in 1985.

    The quality of the image, printer and paper are of much more importance than the amount of megapixels.

    In our school right now we have some 24x36 prints that came from a 300d, and they look great.

    I sent away an image to be printed 18 x 12 today. I will see how well it comes out.

    The 15 x 10 i printed earlier this week was very nice :)

    Apparently a lot of places use the two programs I mentioned above to upscale photos for print.

    They will be added to my list of software for indePrinted :coold:

    Will you be adding a service for people to upload and print picture and have them sent out?

    They can upload, we upscale if necessary, then it goes live on the site (or private if they select a private gallery instead of a public one) then they buy their own print

    depending on the sharpness of the pic 20x30 should be fine

    Well why don't you mention 'dpi' a few more times than once and enlighten us mere mortals?

    This isn't the main forum. We try and give serious replies instead of trolling and giving snidy comments.

    dpi is dots per inch obviously. a lot of printers wont even print at 300 dpi anyway. my camera saves the jpg files at 180. a moniter displays 72 dpi.

    10" @ 300dpi is 3,000 pixels/dots.

    those same 3,000 pixels/dots at 180 dpi would be 16.67 inches.

    dpi plays a huge role in print size.

    to build on that. you could take an 8 x 10 @ 300 dpi. (which is 2400 x 3000 pixels/dots) blow that up to 13.33 x 16.67 @ 180 dpi and lose less quality (because you are still using the original 2400 x 3000 pixels) than if you simply blew the image up to 13x16 @300.

    you wont be distorting any of the information in the picture, you are simply adding more space between the dots.

    That's a lot more informative than a snidy remark like Hypnos_VI did.

    You shouldnt be using either of those if you are going to be serious about this. You should be using a full on RIP program designed specifically for the priinter you are using that will do the upsize as part of the printing process. Not something you upsize first, then print natively.

    Any good quality printer is not using an upsizing program first, they are using a dedicated RIP program.

    Those programs are great if you need to upsize the file or if you are doing your own printing or using a printer that doesnt have a RIP. But you will get MUCH better quality from a RIP.

    That is why someone like White House doesnt want you to resize your photos for larger prints, they let their RIP do it for you with much better results than what most of those programs will do.

    Of course a good RIP can cost thousands of dollars.

    :h5:

    like someone else said already, there are a lot of variables to consider when printing something, not just megapixels.

    All of what quid is saying is true to a point. What he has left out though is that you cant just randomly say you're going to print at 180 dpi in order to make your file go larger.

    You need to take into account what the printer being used is, what its native resolution is and the final output size.

    For instance, something in the smaller sizes, you really should be using something in the 300 dpi range, which, despite what was said, MANY printers DO print at. Some even go to 400 dpi.

    For instance all Fuji Frontiers are 300 dpi printers and all the files should be sized as such. If you dont, the printer will automatically resize the file to that dpi and that can hurt the print quality.

    Many Noritsu printers are 400 dpi printers and accordingly, so should the files or the printer will take it into its own hands to make it such.

    Your average Canon home inkjet, works at 300 dpi for the normal sized print.

    If you have a larger format printer you can go down a bit when printing large. I would never take mine smaller than 240 dpi though when printing up to 24x36 on an Epson 7600.

    You also want to pick a dpi that is a multiple of the native resolution of the printer. So you dont want to just choose a random number and hope for the best.

    So in his example above, you may need to resize the print to 300dpi if that is what the printer requires in order to get better quality than just leaving it at 180 dpi.

    So bottom line is you need to know your printer. You need to know how it prints and you need to know your final output size in order to choose the dpi wisely.
