Photo Quality. Help me out.?

<\'~Inspir

So I'm looking into a new camera. A couple of possibilities I've seen so far are the Canon EOS 7D, Canon EOS 60D, and Nikon D3100.

I'm looking to be able to print fairly large. Not necessarily poster size, but at least a very clear 11"X14". From what I've been reading, you don't necessarily need 15 megapixels to print this size, but to print it at a lower DPI. Can someone please explain that whole thing to me?

What are the other technical specs that go into making a crystal clear, beautiful photo?

I am by no means a professional, however I do take family portraits and things like that for my friends and neighbors, and want to give them really good photos. Currently I have a canon with 8 mp, and 11x14 is almost pushing the limit on clarity. Is it a setting I have messed up or do I need a better camera?

The majority of my photography is human portraits, animal portraits, and some nature/landscape here and there. Along with the hobby photography (friends and camping trips and whatnot).

Answer
you mention 14x11", and at 300 ppi/ dpi, that is 4400 x 3300 pixels

that is in the range if a 14 mp image,

you have a Canon at 8mp , 3344 x 2508 pixels , approx 11x 8 inch size at 300ppi/dpi

price wise, you may be better with Nikon D3100
because the average mp is 12 for other brands,
you may look at necessity of need for 14x11, and compromise or compare,

Need Advice : BEST HD CAMCORDER WITH EXCELLENT HQ?

Nick

I want a camcorder, what do you suggest?
EXCELLENT HD
EXCELLENT HQ
EXCELLENT AUDIO
But big enough to hold in hand.....:D

Answer
Hi Nick,

When looking at camcorders, make sure you look at their maximum data rate (best quality recording). Within a given price range, this will be key to quality. Here is what you will find.

Lower priced HD camcorders will record as low as 5-6 gigs/ hour of video. Under $2000, the best you will find is 11 gigs/hour.

Now, look closely at the few remaining MiniDv tape (still digital) camcorders. MiniDv records at 13 gigs/hour.

To fully appreciate this, do the math! MiniDv has 15% MORE data for a frame size that is 1/6 the size of HD.

Fact is, HD is a marketing term and is a step backward in quality. The lower data rate for a bigger picture are accomplished with huge compression rates. HD relies on reference frames, as few as 2 a second. The remaining 28 frames record only a specific threshold of difference, and are interpreted from the reference frames for most of their image. MiniDv is uncompressed in the brightness channel (important for how we see the image) and has a very low compression in color. Most important, compression is done within each frame. No frame relies on its neighbors for data.

The combination of high data and better compression means that in practice, MiniDv video can be up-converted in editing and have a better picture quality than native HD!

You also mentioned audio. MiniDv excels at audio and records at better than CD quality.

The only functional difference is your MiniDv camera will need a firewire cable (usually extra) and your computer will need a firewire port (expansion PCI cards are about $20.00).

Unfortunately, HD dominates the market. Canon is still producing the ZR960 for $250 and this is a bargain camera. At the $1000 mark, there is the HDV format (Also MiniDv tape but a 1440 x 1080 frame).

Since you did not mention a price range, I'll add that the least expensive camera that is card based HD and meets all your specs is the $3300 Canon XF100

And because most people are falling for the marketing and ease of card cameras, outstanding cameras like the Canon GL-1, GL-2, and XL series are going for under $1000 in the used market. Down the road, if you want card storage, any of these can be connected to an external digital recorder (about $1000).
