ok here goes iam already started a thread a while ago HERE now i was speaking to a consumer today about mega pixels versus the manufacture specs on how large the picture could be blown up. In most camera manuals it specifies that 4 mp can produce a image 2217x1704 however this person did some foot work and his printing lab suggested that 4 mp wasnt enough for a good 8x10 however the manual specs suggest its possible even to a further extent. My first thought was the compresion rate mixed with high tech ccd's and cmos'es could any one shed some light on this for me?
thanks

| At 8x10 that number of pixels would be at approximately 200 dpi. At DPC Prints, your image is considered "acceptable" for public sale if it is at least 150 dpi at final print size, although 300 dpi is preferable. So that (uncropped) 4MP sensor should produce an acceptable but maybe not ideal 8x10 print. |

I have several 16X20 prints done with 3.2 MP camera,they look great for every human eye which saw them.
I don't see why 4MP or 6 MP can't do the same ! |

I have a number of larger prints (20x30" and 16x24") that came from my 3.7MP camera, but can assure you that they would NEVER have made to approval without Photoshop and a bit of tedious editing.
(4,500 x 3,000 pixels in final edits). |

Gotta agree that a quality 4Mpx image will make a very good 8x10. you'll need to look very closely to tell the difference between this and the 6+ Mpx needed to print at 300dpi. It's best if the image is scaled up to match the printer's resolution.

WOW i didnt think it was possible to print that big with 3 mp, so then the way i understand it is that it is possible but isnt really ideal
thanks everyone!

I've blown up a 5mp picture to 20x30 with not editing besides levels/saturation and it looked great. If your looking for a relatively good way to experiment check out www.bigphotohelp.com. TheyĆ¢re the ones that did my 20x30, and the prices and service I got were really good.
Also, if you go to that site and just sign up, when you upload a picture to the website and go to 'print' it, (without paying anything) it will give you a reccomendation of what the biggest size is they feel your picture can be printed at and still retain quality.
Hope this helps! |
