There are two meanings. Originally, HDR meant High Dynamic Range. It originates from imaging where techniques are developed to overcome limitation of sensors. In recent years, the original meaning of HDR is lost. Now it is have evolved to become a new form of kitsch art --- Hideous, Dreadful...

Fool the brain by adding small amount of fine grain noise to increase acutance.

it reminds me of during my school days, just before the exams, how certain classmates will complain "die liao, i didnt revise, i going to fail" etc etc... then results came back, they got 100/100.

some trick i used: 1) Before you upsample/inter-polate the image, denoise it first to remove any grain noise, since they willl become 'blob' artefacts after sampling. also remove compression artifacts first. 2) After upsampling, add noise (preferably monochromatic) to the image to enhance...

1) No need DSLR 2) In fact, no need camera. use your fingers to frame the scenes that you suppose to capture. practice until you know what and why is a good capture. you can spend those saved dollars on movies with cinematography that you like. observe the pictures repetitively. or you can...

Yes, it will. 'Ringing' artifacts is a simple phenomena in signal processing. (see http://en.wikipedia.org/wiki/Ringing_artifacts, http://www.stat.columbia.edu/~jakulin/jpeg/artifacts.htm). but in terms of visual perception, other issues comes into play such as 'visual masking'. so there is no...

No, JPEG does not employ perceptual color similarity detection. The banding which one observes is the result of severe quantization of 8x8 pixel blocks (DCT coefficients actually). this results in only the DC coefficient being retain for storage in the file data. hence each 8x8 block assumes the...

what beautiful palette you've captured! how envious i am now! :D

no need to define it. you'll know it when you see it.

:thumbsup: should make this sticky

just go to JPG Magazine look at these works and forget about your SELF, please.

to TS, unless the pictures are meant to disseminate evidence, just do whatever that is needed to be done to get that picture of yours out. its much to your benefit to stop nitpicking over such trivial issues. if not, might as well argue that industrial light and magic is the mother of all...

while "good" is always argued to be subjective, i believe "bad" is quite universal. night86mare, it very nice for you to share what you read. after googling, i found more articles on this subject... here is the link

recommend these two books: "Camera Lucida" by Roland Barthes ( skipped the first chapter. it is horribly infected by Jacques Lacan's bad writing virus) "On Photography" by Susan Sontag

it is our home, the milkyway. for example, u are in a garden. where u point and shoot, 50 % chance u are taking a pic of the garden.
