Of course, the print quality of an image is of utmost importance. But equally significant is the viewer must accepts the image as its own fact, and responds emotionally and aesthetically. It is safe to assume that no two individuals see the world around them in the same way.
Look at the image below and tell me what you see? I am sure each and every of your answers are different in some ways.
As long as it can bring you into the emotion of the moment the shot is captured, it is a good photo. If you are referring to the technical aspects, it may be the best print, may have the best tonal range etc but if it doesn't tell the story it is intended to, it is still not a good photograph.
Here are two photos i took using a dslr, converted to black and white using greyscale function. Some how it just must appeal as much as i want it to. would anyone like to comment what is wrong with them? thank you
Firstly I am not a pro, nor do I consider myself "good". But I am passionate about B&W photography.
To me a good B&W photograph is a photograph that conveys what the photographer intends to, and hopefully the viewer feels the same way! But all in white and black, of course!
I personally do not think that a black & white photograph must have the blackest black and whitest white, with all gradations of tones in between. This kind of full range tones is a photograph to show what good tones are, but they are not the "essentials" to a "good" B&W photograph which should have as its basis in the content, aas ain all imagery.
A B&W can have extremes such as lithographic style, where there is only blacks and whites, making for very graphic shapes and patterns.
Or it can have a very narrow range of contrast such as a woods in misty morning, with no blacks and whites.
But of course, the majority of B&W photos will have tones and contrast somewhere like this picture of "Two Italian Girls"
BTW, this image was taken with the Olympus E1. Color image was changed to B&W in Channels Mixer, adjusted with curves, with dodging and burning as required in certain places.
Although my personal preference is for traditional B&W, I have absolutely no problem with using the digital camera to make B&W pictures. I think they can be very nice, such as the one shown by Zaren. But a digital B&W will have different characteristics from a traditional B&W. What one prefers is another matter.
