Interesting that the larger prints seem to have more detail than the smallest one. Of course, it could have something to do with me viewing them on an iPad Air.

Since MT is in the business of photo, I'm sure he will print for most anyone. The real question is can he post the prints to you and work out a price. There isn't much MT can't do.

If you use PS or Elements to PP try the free trial download of Perfect Resize. It beats resizing in PS or Lightroom hands down. It's easy to use with no loss of sharpness or color. I wouldn't be without it. It takes me about 2 minutes to resize a photo.

Personally, I find answers like that very helpful! They help me know which comments to ignore.

Do you know if Perfect Resize works with Lightroom too?

A couple things The program "Perfect Resize" will make a 36 x60 image out of most anything--but you do need the best quality you can get to start with--then {I am assuming you are going to use a cheap place for printing--that is ok--they don't like their machines to break, so generally they have pretty good machines--but--they exercise no control over how the machine handles color--so you have to figure out what the color balance the machine has by having it print some (smaller) prints until the print you get back looks like the image you want--be sure they are using the same machine for your test prints as they will use for your big prints--then, as the paper can only accept about 200+ lines of information 240 DOI will work fine--no sense in sending the paper more information than it can accept--anyway--good luck

Sorry, but that's not really true.

It completely depends upon how high quality you need in the finished print.

You can make a 40x60" from the 18MP APS-C crop sensor image produced by the T2i, but it simply will not be as high quality as it would be if you used the 36MP full frame size sensor D800 instead. Even better, rent a "medium format" size sensor camera such as a Leaf/Mamiya that produces 80MP images!

It's really unlimited, the size to which you can up-rez an image. Your T2i can natively make a 60" image at about 100 pixels per inch, so the amount of up-rezzing needed (as determined by the printer) may not be all that great. One printer I work with asks for minimum of 170 ppi, but I usually try to use and provide 240 ppi. There are softwares and post-processing techniques that can be used to greatly improve the quality of greatly up-rezzed images. But it still matters a lot the quality you're looking for, how far away from the image will people be viewing it and other, similar factors.

Whatever camera you use, to get the very best it has to offer, it would be best to "fill the viewfinder" with the subject so that cropping is not necessary. Keep to a relatively low ISO to minimize noise and maximize resolution at the sensor. Also use high quality lenses that have maximum resolving power. And you need to use the very best techniques to get best possible exposure, correct white balance, precise focus, adequate depth of field, etc. Be sure the camera's sensor is as clean as possible. Any "sloppiness" in your technique will be greatly amplified doing so much enlargement.

I'd shoot RAW to have the max possible data to work with in post-processing. There are many different softwares that can be used to PP the image, depending upon what's needed. Depending upon the printer's requirements, the finished and correctly sized image might be saved as an 8 bit JPEG (most common) or as a 16 bit TIFF (rarer for printers to be able to use these). When saving as a JPEG, I would go with uncompressed & max quality.. even though this makes for a bigger file (might be an issue if submitting it online). I'd do the same with TIFF, max quality and uncompressed, but this will be 2X the size or more than a JPEG would be.

So it really comes down to what you want to do with the finished print. When you refer to a "poster", it makes me think of a less critical type of print (compared to, say, a fine art print). Maybe all you need is a good exposure from your T2i. Or maybe you are looking for something higher quality, and will need to step up to a higher resolution camera to get it.

Craig, I'm glad most everyone tried to be helpful and was especially impressed with MT Shooters advice. I ordered a Nest Tripod Head, which they had on sale, a few months ago and am very satisfied with it, and will sure consider making future purchases with them. Take care!

Yes it does load as a plug-in in the Edit In menu.

I'm fixing to print a 8 x 10 foot wall mural, from a 15 MP image. It'll come out fine at 30 - 40 dpi.

Every accomplished photographer was a novice once...including you.

CraigFair Loc: Santa Maria, CA.

The 30-40 dpi is that a ratio for the increased size of the original image at 300dpi???
Craig

Michael Hartley Loc: Deer Capital of Georgia

300 dpi, is pretty much only used for business cards, and such, anymore. Don't know what it was saved as, probably 72. Plus, I'm not processing it, just printing. Be a combination of vector, and raster images.

Yooper 2 Loc: Ironwood, MI

Yes. Choose Photo>Edit in>Perfect Resize. Perfect Resize is the Industry standard. I don't think you would be disappointed in it. Just remember that the end results will only be as good as the photo you are resizing. That means good clarity, color, and detail, etc.
