Let's say you want to fill a wall ... with a 20x24, or a 30x40 ... or even a 40x60 ... what makes it worth the effort?

Whats in & the quality of the finished image .

an over of cricket, cucumber sandwich, warm beer, and some gentlemanly discussion should kill this post dead ... you can't converse with muppets ...

What's an over of cricket? I really don't care for cucumbers. Can I have a cold beer? Oh and a cheeseburger :) and does size really matter? Is it the length of the wand or the skill of the magician? Only the Shadow knows.

An over of cricket is like an Inning in baseball ....

It gives each team (of all 11 players) each - a chance to be at the bat, and then, to field - against the opposition ...

Depending on how THAT turns out ... then, the next round is scheduled ...

Cucumbers are great in coleslaw, Frankie ... did you ever have them that way?

Size DOES really matter, Frankie - when you're thinking of blowing up an image ... many images can't really make it well to ANY of the quoted enlargements!!!

I love coleslaw.... I will still pass on the cucumbers. When I was a kid I loved em fresh out of the garden with a little salt.
now you really wanna talk about print size. well some software (PS being one) use interpolation. its a smart guessing game which will lay down ink by looking at the surrounding pixels to determine color/density etc. If you understand the algorithms used to create the you can mathematically determine (best guess) what ink/color to laydown. It actually works really well. Back in the day when we had access to the mars images from space, from the NASA web site. I was able to print a very large and accurate image taken by lander rover thingy we put on mars, and produce an really great mars scape about 12 ft long and 3 ft wide on an hp pro roll printer. So you could prolly get pretty reasonable results to a poster even if you took the image with your phone. When viewed from an appropriate distance would look OK. Think about billboards and half tone printing (which is still done in news papers. if you wanted to build a good image you could use bump exposures to lay in dots where none existed. If you do this for each of your color separation half tone negatives you can build a pretty good image. There are many ways to enhance images with the right photo mechanics. Print labs do this all the time to print some really awful images and the peeps getting their prints think they are photo geniuses. they even get into heated discussions about how my little sensor is just as good as your big sensor..... besides photography I do have a diploma in lithography. SO GUESS THIS MEANS I'M Skill Of the Magician Guy :) hey just sayin.

Take a section of the photo that contains the focal point. Suppose you want the image to be 40 x 50. Print an 8 x 10 of a section that has 1/5 of the pixels in each direction. That way the resulting image will be the same size as the poster (but only a small part of it). If it looks OK (view it from the typical poster-viewing distance) then it will make a good poster.

The information re cricket is incorrect - you have just described an innings.

From wikopedia
"In the sport of cricket, an over consists of six consecutive balls bowled by a single bowler from one end of a cricket pitch to the batsman at the other end.

After six deliveries, the umpire calls 'over'; the fielding team switches ends, and a different bowler is selected to bowl from the opposite end. The captain of the fielding team decides which bowler will bowl any given over, and no bowler may bowl two overs in succession."

Content and space.
The technical quality has to be ok.
The largest we have had done are 30"x20"

I prefer to print 10"x8" (or A4) and rotate the images displayed.
At normal viewing distances you do not neeed a lot of mp. Our children gave us a framed tryptich of 5"x7" prints derived from 2mp images.
It looks ok.

Sounds like you could be a real Merlin, there, Frankie ... btw ... I hear MERLIN loves cucumbers ... AND Cricket!!!!!

Chris T Loc: from England across the pond to New England

That sounds like a real neat way to deal with it, Dirt ... I never thought you could do that ... but, I guess it makes a lotta sense!

Okay, Richard ... so, I'm not perfect ... but, at least - I was close. Hey, I was brought up behind a cricket bat! ... But, I must admit - it's a long time since I played. Over ... Innings ... what's the diff?

All I do remember is - it's a helluva tedious game ... especially, if you're NOT at bat!!!!
