1000th Download

Took me 15 months to attain it, with a revenue of $932.54, or an RPD of $0.93.Total image online is 1520 and thus an RPI of $0.61.I think I am definitely NOT a microstock superstar.I like to think I am typical, but maybe I am less.Anyone care to share? :-) continue reading

Lehman Brothers Building on Seventh Avenue, New York City

I was in transit between Montreal and Singapore on the 5 Apr and landed in New Jersey with some 10 hours to wait for the connecting flight. So I took a bus to downtown New York City, dropping off at Times Square, with my camera, of course.I walked down the famous Seventh Avenue down to Central Park and back, and shooting the usual icons, like the Naked Cowboy. And then there was some crazy wedding photographer doing his photography smack in the middle of the street, stopping the yellow NYC cabs... continue reading

Making HDR Pictures (Part IIC)

HDR pictures generated by Photomatix per se are not good enough for stock photos.There are three main defects that needs to be removed before it is of suitable quality, namely artefacts, high noise levels, and severe chromatic aberrations.These defects exist even when maximal effort have been taken in the capture (Part I) and the generation (Part IIA and Part IIB) to minimise them. But now there is a high possibility - more than 90% from my experiences - to improve its quality to an acceptable... continue reading

Making HDR Pictures (Part IIB)

(This is a multi part article. The other parts are here: Part I, Part II, and Part IIA.)The four tabbed panels below the histogram in Photomatix's Tonemapping screen, are Tone, Colour, Micro and Shadow/Highlights.Tone works exactly like Levels in Photoshop.Color fine tunes, via the Temperature slider, the WB set before the HDR was generated. Color also gives control of the saturation in the highlights and shadows, and this may be set together with readjusting the overall saturation, as... continue reading

Making HDR Pictures (Part IIA)

When you load pictures, in RAW format, to Photomatix for HDR processing you specify what algorithms the processor is to use to correct for camera movements and objects motions in the scene. There are two algorithms for each.In camera motion correction I usually take the more compute intensive option, ie to align the picture by matching the features in the scene instead of the simpler vertical and horizontal corrections. However sometimes this complex algorithm fails. Then I revert to the simpler... continue reading

Making HDR Pictures (Part II)

In Part I, I wrote about the capture of images for processing into HDR pictures.I need to add something I left out, namely that the capture should be in RAW format and not JPEG.And the reason is that HDR processing creates lots of artefacts. To minimise this we start with minimising artefacts in the first place at capture. JPEGs create additional artefacts of its own, thus aggravating the "problem" after HDR processing.Of course it may not be any "problem" at all to your eye and your aesthetics,... continue reading

Making HDR pictures (Part I)

There are two steps in making a HDR picture, namely the capture and the processing.Actually this is the same as with the making of all photographs, but there are differences for the creation of HDR pictures.I will talk about how I capture images for HDR in Part I, and talk about the processing in Part II.So firstly, in the capture, the question is, what scene or subject makes for a good HDR picture?To me this will be one in which the scene's dynamic range is wide, exceeding maybe 5... continue reading

Chinese New Year

It is approaching the Chinese New Year soon, an occasion celebrated around the world wherever there are Chinese people.And the orange or tangerine is a symbol associated with the event.It is a visual pun for the word gold in the Chinese language, even in its various dialects, and thus meaning wealth or prosperity.And here it is pictured on a red background, instead of white, as red is the colour for auspiciousness or good luck.(White on the other hand is a color of mourning and death.... continue reading

Live View and Off-Camera Lighting

This image was created by shooting underneath a leaf encrusted with water drops after a shower.The camera, an Olympus E3, was positioned under the leaf and focus and composition carried out by means of the Live View Screen swiveled out from under the camera.And the leaf was illuminated from the top side by remotely triggering a off-camera flash unit.I suppose there are more creative pictures possible using these features of the modern digital camera. continue reading

Time is Relative

Yeah! I finally got an image accepted for Assignment!This image was created via layering multiple exposures of a clock ticking, with each shot taken 1 sec apart, coinciding exactly with the second hand arriving at the mark.These multiple images were then layered in Photoshop with each succeeding layer's opacity a constant fraction less than the previous one. In this case I think I used 75%.But such layering would not work if not for Photoshop CS3 new Auto Align Layers by Content, which... continue reading
