Which way of recording will give me an image with the best definition; shooting with a 6 megapixel camera with image quality of extra fine or with a 10 megapixel camera with an image quallity setting of fine? Allso, what is the difference in file size in MB between the two?..

Are you talking DSLR or P/S ???.

...on the camera, the lens, the lighting, the exposure, the subject, the photographer, the amount of cropping, the size of the print....

I don't think there is an answer to this that has any relevance in the real world..

Everythign else being equal, the 10mp will resolve more detail. But go back and read what arrowman wrote..

Question applies to a DSLR..

With a larger sensor...you have less noise with a 6mp at the settings you asked about...Assumming ISO 100 or 200....

But the 10mp senser will give you more image detail,,but it may have a little more noise too..which will destroy finer detail.....

I had a 6mp DSLR (Canon D60) and went to a 10mp DSLR.(Canon XTi)....The 10mp was also 3 generations ahead in tech advances and Image Prossesing.....

So for me The newer tech and 40% more pixels made a huge differnce in IQ and detail...and LESS niose too....

I would say, IMO, if the two camera's are fairly close in tech usage...the 10mp may have an edge on detail (some...The lens plays a big part too...

(I have a Tamron SP 28-75 f/2.8 that has been recalibraded by Tamron. and the Quality and resolving power of the GLASS is VERY NOTICABLE over the Mid Level Canon EF 28-105 f/3.5-4.5 USM).

So, several factors play out here....If you desiding over a Nikon D40 and a D40x,,,The D40x will most likely have the better IQ (More recorded detail over the D40)...But the D40 may have less noise over the D40x.

If you desiding over a Canon Rebel -6mp- (ORG) over the XTi....The XTi (10mp) has a bigger edge on IQ over the ORG Rebel....

Image definition I am asking about is the result of an image shot with a DSLR of 6 megapixels at an image quality setting of extra fine compared to that shot with a DSLR of 10 megapixels with a camera image quality setting of fine. Both shots with the same lens, same f stop, same subject, same shutter speed, same temperature, same lighting, same subject distance,on the same day only minutes apart and printed by the sameperson to the same reproduction size by the same computer or printer from the same CF. WHICH WILL BE THE BEST/..

Pointless question, really..

Anyone who really cared would just set the higher MP camera at the highest setting (lowest compression) and get the best of both worlds..

Chances are the 10MP camera is newer, and probably has a better chip, too..

The difference between extra fine and fine is a matter of compression..

Since in jpeg most of the compression happens in the color parts of the picture, and because you are printing the pictures you will see no difference. The part about printing is important. If we assume that you are printing them both at 8X10 then with either camera your at the limit of the printer resolution. If you print larger you may still not see any significant difference untill somewhere past 16X24..

But I agree with Arrowman, this is just a thought experiment with no real world application.A member of the rabble in good standing..

I thank everyone for their input, it has helped me to decide whether to replace my 6 mp camera with a 10 mp camera. Thank you for your time and thoughts. ridgerunner..

I'm guessing that based on this thread your decision would be to not go for the 10MP camera? Fair enough. However, if I may add a little more:.

There are reasons why you might want to change to a 10MP camera. Image quality - at least in the terms you have described it - is not one of them..

If you'd like to consider other questions, beyond this, and be more specific about the camera makes and models you are talking about, then maybe there's more to discuss..

Which way of recording will give me an image with the bestdefinition; shooting with a 6 megapixel camera with image quality ofextra fine or with a 10 megapixel camera with an image quallitysetting of fine?.

I'm interested in your use of the terms "extra fine" and "fine" for the image quality (compression levels). Are you talking about specific camera make and model(s) here? You need to remember that terms like "fine" and "extra fine" are specific to particular cameras, and not generic terms. What Canon (e.g.) calls "extra fine" might be what Nikon (e.g.) calls "fine"..

If you want to compare images between two different cameras, it's really about "which camera produces the better image at it's maximum quality setting?". Asking about "10MP fine" vs "6MP extra fine" doesn't work, no-one can answer that..

But, as I (and others) have said, the answer (especially for the 8x10 etc example that you have given) is probably "no difference"..

That does not mean the 10MP camera may not be better in other ways. But in general I would guess that if image quality is your focus, I'd say forget about it, keep using the camera you've got..

Allso, what is the difference in file size in MBbetween the two?.

Forget about that aspect. Storage is cheap. The last thing you want to do is start making choices about your camera based on how much space the images will take up..
