Hi all,
if you have 12Mb pixel camera, can you see the picture sharp and clear in 100% at image editor(photoshop)?
because when i put the view ratio 100%, the picture is less sharp and clear.
the most sharp and clear i can see is at ratio 60-70% at PC 24" inch lcd screen with res 1920 x 1080.
is this normal or the picture i take still not good enough?

When i compare photo from 8Mb pixel camera, i can see sharp and clear in 100% view ratio.

thanks for any reply/ info.

why pixel peep?

don't you think this photo looks nice?



This is my fav display size on forum boards. Very optimised and very hard to find flaws.

How often do you view this size online or even published?

Why make your life miserable pixel peeping for sharpness?

What I said make sense to you?

As long as the sharpness is there for the usual size you post looks sharp enough, why bother at maximum size?

I mean, since already have 12Mb pixel camera, should utilized the camera better :D

I just wonder, even with the full frame highest end dslr camera with the highest end lens, is the 100% view still can not be sharp and clear?

FYI, I am using a 5DMKII, 21mega pixel and I am not the least concern about sharpness (sharpness also depends on the lens u are using). Not all photos had to be pin point sharp.

the sharpness come from..... good lenses, proper focusing, proper use of aperture setting, proper using of shutter speed setting, proper camera handling technique, in camera picture control setting or post production, without any one the above, 24MP camera also can produce crap.

about focusing as mentioned by catchlights, i will share a tip for u TS.

- use only 1 focusing point (usually the center). the rationale is using all focusing points, the camera sometimes is dumb enough to focus the wrong object.
- want to learn focusing better? Try use a manual focus lens. If you can handle a manual focus lens well, you will definitely have no problem using modern AF (auto focus) lens. That's how i train myself up in this area. By the way this photo i took above is using an Olympus Zuiko 200mm f4 lens + EOS adaptor with AF confirmation chip on my 5DMKII. Focusing wise, no longer auto but manual focus.

new2011, such comparisons are meaningless in real-world photography. Generally a higher res camera is going to be more demanding of lens quality and photographer technique, if you're going to pixel peep. But 12MP vs 8MP is only a 22% increase in linear resolution, so there shouldn't be a whole lot of difference. More importantly, are you 'testing' properly -- same lens, same image, same conditions? If not, your little test means very little. A 12MP DSLR with a crap lens is going to be outperformed by a 8MP DSLR with a great lens. Great gear in the hands of a poor user will render poor results....
Catchlights already listed out the factors that can affect your final result.
And as sinned79 already said, don't waste your time pixel-peeping. Most pixel-peepers turn into gearheads, BBB the best gear in search of the elusive totally sharp image, and miss the point completely about what photography is about.

The best utilization is when people go "Wow" about your pictures regardless which size they are. It is when you get the pictures that you intended to have or when you discover new ways of creating pictures.

u also left out 1 more: final output size
just adding on to uncle ben...
perceived sharpness is not the same as actual sharpness hahahaha


the smaller the image, the "sharper" it gets...

its almost impossible to get a 100% sharp image with crisp edges even at 100% (unlike vector images). too many variables to tackle already, especially with regards to things like good lenses.

my take would be make ur images a tad smaller... it will look better

On top of what has been said.

1:1 on the 8mp camera is not the same magnification as 1:1 on the 12mp camera.
If you needed to match the o/p of the 8mp to 12mp camera, you'd have to upscale (ie. extrapolate pixels). Losing actual detail in the process.
Alternatively you can downsize the 12mp camera o/p to match the 8mp camera. Then it would be like you viewing the 12mp o/p at 70-80% size (or something along those lines).


In other words, the 12mp camera can be viewed or printer larger than the 8mp camera.
