Print question
Assuming that the camera and photographer are right on, the lens is good quality and there is no pp, how large a print should I be able to make from a 30D before the image begins to deteriorate? Thanks..

I've done very nice 12x18s with my 6MP D60..

How deep is a hole?.

You can make a billboard from it as long as you view it from the distance that you view billboards at. The general rule of thumb is that if an 8x10 looks good, you can print the same picture as large as you want, provided that you view it from an appropriate distance..

If you're not going to view from an appropriate distance, then all bets are off...

Excellent point..

Also, who does the printing makes a difference. I've also had a couple of 6MP images blown up by a professional lab to approximately 3' x 4' and was amazed at how well it came out..

I have several 20x30inch and many 16x20inch photos from my 6mp pentax *istD. results are very good..

Also have printed a 7shot 120degree panorama to 36x16. that could easily go to 48wide if desired..

It should be noted tht I do my cropping in the camera; it is called composition. but this means that I am using all 6mp in the final pic and not cropping some away. if you start with a 10mp camera and crop away 40% you now have the equiv of the 6mp but it is noisier..

My 20x30 shot of the mackinaw bridge on my bedroom wall..

The lights on the bridge are not points of light, they are actually globes...

I use a 6mp 300D and have printed 16x20 and also 20x30....

Very close the 20x30 has lost a little detail but looks great from a few feet away...it hangs above the mantle..

As another posted above, if you want to print big...it is best to compose well and not crop..

I used MPix....

Thanks for the replies. I am encouraged. All will be printed without cropping and need to be relatively big (16 x 20 minimum). The 8 x 10's look great..

Yes, I think you should be greatly encouraged. Although I have not produced massive prints myself, what I have seen and read tells me it is very feasible..

My print shop has shown me a 16x20 produced from a 3MP camera. Up close you can tell. From a reasonable distance - while it's not glossy magazine standard, it is very satisfactory..

For me, I would use the arithmetic to check out just how far I'm pushing the envelope..

The arithmetic tells me that with a 6MP image (say, 3000x2000 pixels) I can go to about 10x15 inches at 200 dpi - OK 200dpi is less than optimal, but it's not poor either. So I'd be very confident of printing at that size, or even above..

One little thing that is possibly worth keeping in mind:.

There's 2 aspects to printing large:1. DPI and whether you get "jaggies" (visible pixels).

2. If the image has been interpolated to produce the required (usually 300dpi) resolution for the printer, the extent of degradation (softness mainly) that results..

Now, what we need to remember is that 1. is not an issue with most labs - their equipment will (should) automatically upsize the image to 300dpi (or whatever, but 300 is ususally it). So you coud give them an image of any size (number of pixels) and expect it to be printed without jaggies..

The real question is - how good is their upsizing (interpolation) compared to what you could do at home? In other words, is it worth your while to upsize the image yourself, or just give it to the lab as is? Obviously the answer may vary depending on your skills and the quality of your lab. But generally speaking I'd be comfortable with letting my guy do the work..
