It all depends on the context of the question.

If someone asks 'what do you think of the image quality of this picture' people will bring in the photographic skills of the photographer.
If you ask 'does f16 give better image quality than f8' the assumption would be they are referring to sharpness, contrast, dynamic range etc. Ditto for lens A/lens B

Show us in photographic terms your perception of Image Quality and a Quality Image

Add kit used and settings...and the all important PP

I didn't make either of those assumptions Wink

That's the point - when someone asks about image quality, it means different things depending on who they're talking to.

For me it's more about evoking a feeling, for others it'll be down to what a print looks like under a magnifying glass.... who knows what else people assume.

I am not sure why people find it so hard to divorce aesthetic quality and image quality, aesthetic quality is driven by the grey matter between the photographers ears and image quality will largely be defined by the kit in front to the photographers face (assuming it is used in a manner to get the best out of it) Smile

Surely Image Quality is very easily defined much the same way as Image Quality is tested in a bench lens test. A Quality Image is another matter.

Umm... interesting how open the definitions are (or perhaps closed).

As ever - the term relates to the context.

In a magazine reviewing a new bit of kit the context is likely to be technical and measured scientifically where possible. In an exhibition, less so (but perhaps not always). I like Keith's distinction too - a fair point well made.

Put simply you charge people for your expertise when possibly you are not as knowledgeable as you purport.

IQ is IQ.....I explained what it was and many after me.

perhaps you could search epz or the web, pop down the library and look at a book or 2...its all there.

Its your business...not mineWink
