Good critique......has an equal amount of positive and negative comments...answers 3 questions:What is good about it?What is not good?How could it be better?...identifies the technical, objective factors that define a photograph and evaluates them.
The four standarts:-value-clarity-composition-presentation
Value-range of light in the photograph-in general its good to aim contrast-good balance of black and white-range of grays (distinguish between good and bad grays)how to improve the value:-most common is incorrect exposure when taking the photograph
Clarity-whether it is correctly focused-subject may be either sharp or soft -sharp focus: edges are clearly defined -soft focus: edges blur a bit-center of interest is focusedHow to improve clarity:-focus is the most common problem-using too large an aperture-shutter speed
Presentation-care and skill/ how clean is it?-problems: white flecks, fingerprints, scratches, dark circles
Composition-Is there a point of interest? (should be near the middle of the frame)-good cropping? wasted space? (frame should narrow in on whats important)-balance: top-heavy, lopsided, boring? -static balance: just sits there, but can be effective -dynamic balance suggests movement-Aesthetics: which photographs have that something, and which dont
This picture has a high value, because it has a lot of contrast and a high rangeof black and white. It also has a range of grays. It is rather softly focused but itstill has a high clarity and the center of interest is in focus. It is very clean andthere are no scratches or fingerprints on it. It has a good composition becauseit is an interesting picture with good cropping and it has that something.
This picture has a high value because there is a lot of contrast between the rose and the background. It has good clarity and is sharply focused. The center of the interest ( the rose) is in focus.It is very clean without any scratches, so it has a high presentation. The cropping is good and there is no wasted space.
This picture doesnt have that much contrast. It has a range ofgrays but I would improve the contrast to get a higher value. It issoftly focused, which looks good. There are no scratches.
