I have received many comments regarding the rather incredible sharpness of my photographs shown in my blog. Some questioned how I managed to obtain sharp images, while others requested me to share my techniques on how to process the photographs to increase the sharpness. Seriously, it was not so much on the processing part.
Everyone loves sharp images. In order to accomplish tack-sharp images, the following steps are important:
1) Make sure your focus is dead on accurate. On DSLR (or large sensor cameras) even slight miss-focusing can cause soft images.
2) Shoot at low ISO settings to capture maximum amount of details while minimizing noise.
3) Use fast enough shutter speed to mitigate blur due to hand shaking in dim lighting situation.
4) Mount the camera on tripod for slow shutter speed works
I usually do perform a little sharpening on my photographs before resizing, but it is crucial to get your image blur free and as sharp as possible while shooting. If your image is out of focus, or blurred due to shake or subject motion, no matter how much post-processing sharpening you apply it will not be able to salvage the broken image.
If you have experienced using Olympus E-System or their newer Micro 4/3 Pen series cameras, you will realize that one of the many strengths of using Olympus would be the absolute sharpness. Though the sensor size of 4/3 or micro 4/3 cameras are smaller in comparison to competition, the amount of details being able to be captured by the superior quality lenses is nothing short of breathtaking. Olympus Zuiko lenses are so sharp even being used at wide open aperture (most other brands’ lenses require stopping down to match the Olympus lenses’ sharpness), and this is no joke. Now mount them on the Olympus E-5, the combination is no slouch. Comparison tests (which were being done in-house by Olympus) have shown the overall sharpness and resolution to evidently surpass what the 18MP Canon 7D and the 12MP Nikon D300s can achieve.
With the proper techniques and execution on field, using significantly superior optical quality lenses with a respectable professional grade camera body like Olympus E-5 can really make a difference in delivering absolutely sharp images. I know that we are not really very supportive of the pixel-peeping culture which has gone wild in the modern photography world, but to answer the questions of you beautiful readers out there, I shall post up 100% crop images.
All images were taken with Olympus E-5. General camera settings: Noise Filter OFF, Noise Reduction OFF, Sharpness 0, Contrast 0, Saturation 0, Picture Mode Natural. Lens and exposure settings used are as stated below following the image. All images straight out of camera with no post-processing applied.
