How many MegaPixels are enough Megapixels?

I asked this question back on April 11 of last year. I am kind of

wondering if anything has changed. I ask here because I am less

likely to get the "I'll be less unhappy with gigapixels, maybe" answer.

 

So, is 6mp enough for what your clients need, or do they need 8? How

about 10? If you use 8 or 10, do you find yourself downsizing or

shooting at a lesser resolution at all?

 

Thanks

Depends on what you're shooting, how much you like to crop, etc. More megs equals more

options.

 

Handling file size and storage is of little concern to me. Computers are evolving quite

quickly with faster and faster processing. RAM capacity has increased and has reduced in

price, and big scratch Disks to supplement PhotoShop are a dollar a gig or less. CF/SD

cards are increasing in transfer speed and capacity, while dropping in price per meg. Hard

drives for image storage are less than a dollar a gig and dropping

 

When Canon hits the streets with the 22/24 meg camera, I'll get it because I can use every

meg I can get. However, that doesn't mean I have to use it. PS ARC allows you to select the

size while processing, but retains the full RAW file for any future use. RAW files like DNG

provide lossless reduction in size, and I believe similar technology will be further

developed in future for even smaller RAW file storage.

 

My current meg champ is a H2D 645 22 meg. sensor dedicated digital camera, that will be

upgraded by Imacon to 39 meg in March. It's for commercial applications, but since we

have it, we'll use it for weddings also.

There were and are lots of folks shooting with 4 & 6 mp cameras. What a lot of people ignore is that as the mp goes up, and the pixle pitch on the sensor goes down, it gets much more difficult to reach the theoretical maximum resolution. Less than excellent lenses, slight amounts of camera shake and anything other than perfect focus (which AF often doesn't produce) any you don't get the sharpness the camera can deliver. Landscape photographers working on tripods may get the most out of a camera, but the way a lot of wedding photography is shot it won't matter. 12mp is probably the point of diminishing return with APS-C sized sensors, and 16-18 mp with FF sensors. We would benefit much more with sensors that had greater dynamic ranges that would make good use of 16 bit depths.

Another thing to consider is what size prints will you be making. If most of what you print are album size 5x7 and 8x10 then you may get on just fine with 6mp. I have seen studio shots from a Canon D30 printed to around 11x16inches and I was very supprised at how good they were. I have also seen similar sized wedding portraits from the Canon 10D and the 20D and they have also been very good. Remember also that a close portrait of the B&G will hold up much better than a 40 person group shot because the details are much small in the group shot.

As Bruce says there is more to the equation than just megapixels, whatever you get, couple it with the best lenses you can buy and if you can't afford it, buy borrow or beg. Using a substandard lens on a 10 megapixel body can easily reduce it to the equivelent of a great lens on a 6 megapixel body. Added to that, for formals and portraits use a monopod or tripod. Yes I know that it goes against the grain for so called PJ photographers but what can you really handhold on a 12 megapixel camera for a 40+ family group or when a 20X30" enlargement might be wanted? When you can use one, do so. If you can't then up the iso slightly and use a higher shutter speed. Remember there is no grain to hide the little imperfections anymore. Most of the time photographers are not maximising the resolution of their cameras due to technique and upgrading to higher resolution doesn't help.

I completely concur with what Ben R. just wrote. For posed stills the single best thing you can do in improving your output is use a tripod. After that it is your lens (and then of course the lighting which I think is the hardest to master).

<p>

For sure shoot in Raw and do all of your conversions with something at least as good as PS ACR (Adobe Camera Raw, now at version 3.3 to support all the new cameras released since Nov. 2005). (ACR 3.0 was released when PS CS2 was released, almost one full year ago aleady, time flies.)

Canon's new 10MP 20D replacement upgrade ($1500) will be announced in less than 2 weeks. Failing that the $2900 Canon 5D rocks (assuming Canon makes you happy).

People view albums from less than arms length away. The more tonal gradation and detail

the print has, the more dimensional it looks ... as in "looks more real"

 

The eye mixes digital gradational edging from a distance. Up close is another matter.

 

I've shot weddings with a Nikon 1Dx and a Canon D30, and they were fine. I look at the files

now and they don't look so good anymore. Clients didn't care. But my expectations of myself

have become more critical and demanding concerning digital.

All that the MP indicates is size. A 10MP image would be about 3872 pixels wide by 2592 pixels high. It can be a sharp and clear 3872 x 2592 image or a dull, blurry off color 3872 x 2592 image. As others have said that all depends on the lens, camera construction, sensor, etc.<BR>

Which do you think would deliver the better photo:

Thanks for all the fascinating input. James, well made point. I am going to keep that in mind the next time I run into a "photographer" with a "pro-sumer" camera.

 

About 10 months ago, the loose consensus was 10Mp was enough as long as you do not need to crop. Marx�s point about raising our own standards was interesting.

 

Thanks

Whatever the newest MP count is tends to be enough. Not to long ago people shouted that 3MP was enough for weddings. People will say anything if they think it will save them a buck or two. Who would willingly tell clients that they were getting junk compared to what film is capable of delivering? I cant help but laugh at those �pioneers� who gave up 35mm and MF and switched over to digital with the old D1s and DCS620s. I wonder how many brides have albums full of pictures that look like they were shot with a coolpix! But really 5-8 MPs seem to be enough for albums and modest enlargements as long as no cropping is required. Having said that, more resolution, less noise, and more dynamic range is always a good thing.
