HDR photography if you have never heard of HDR

My HDR 1 was rock-bottom shocking (in a funny way). HDR 2 was an improvement. Since then I have developed a healthy addiction to HDR and post-processing (see Andy Confesses here). Most of my recent photos on this site are HDR or at least a fair attempt.

I am still on a big learning curve and the next goal is to become well-versed in Photoshop (I know a few basics only). One of my favourite artists in this field right now is Jimmy Mcintyre – click here. Plus Art Hakker also always grabs my eyes.

This post is dedicated to my beautiful life-partner who often wonders why I disappear from home for a few hours with my camera and then return home, only to sit in front of the computer for a few more hours.

The state of “meditation” I achieve staring at, fixing, mixing and creating the photos is very important to me. It nurtures and calms my soul. Nothing else is important at this time; neither pleasures nor worries.

To save time, let’s use Wikipedia’s explanation of HDR. I will also insert my set of images (only displaying 3 of the 9 used – exposures +4 to -4, ISO 100) and the final results (one shown below).

The final results were achieved in 1.5 hours (post-processing time after the 9 photos were taken off the camera and loaded on the computer). Still lots of extra skills needed and I will have fun acquiring same in the years to come.

“High-dynamic-range imaging (HDRI or HDR) is a set of methods used in imaging and photography to capture a greater dynamic range between the lightest and darkest areas of an image than current standard digital imaging methods or photographic methods.

+4 (Large)

HDR images can represent more accurately the range of intensity levels found in real scenes, from direct sunlight to faint starlight, and is often captured by way of a plurality of differently exposed pictures of the same subject matter.

HDR methods provide higher dynamic range from the imaging process. Non-HDR cameras take pictures at one exposure level with a limited contrast range. This results in the loss of detail in bright or dark areas of a picture, depending on whether the camera had a low or high exposure setting. HDR compensates for this loss of detail by taking multiple pictures at different exposure levels and intelligently stitching them together to produce a picture that is representative in both dark and bright areas.

HDR is also commonly used to refer to display of images derived from HDR imaging in a way that exaggerates contrast for artistic effect. The two main sources of HDR images are computer renderings and merging of multiple low-dynamic-range (LDR)[4] or standard-dynamic-range (SDR)[5] photographs. Tone mapping methods, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect.

It’s gonna take some comparing

It’s gonna take some comparing to tell if the first set of photos at this location HDR 3 (high dynamic range) final have been improved on.

So if you have a minute, click on HDR 3 (high dynamic range) final, view the photos and then look below to see if the last 2 months of dabbling in HDR has reaped any positives (the quality of the HDR not the shot or view).

I’m using a Canon 550D with standard 18/55mm. Just discovered Magic Lantern to get more than 3 bracketed shots at once.

I leave ISO at 200, the F-stop is set depending on what the camera auto sets on AUTO mode (I gauge then set back to AV). I focus with auto then set back to M before shooting. The stabilizer is OFF.

Photomatix is my processing friend.  

Let me know what you think – I love hints and advice from any experts out there.

Rubber Engineering & The Mind

On the mind, Oliver Wendell Holmes reportedly said “Man’s mind, once stretched by a new idea, never regains its original dimensions.”

Turning to rubber that usually stretches and regains its shape, this afternoon I was given a guided tour of Rubber Engineering in New Germany by the founder, owner and Managing Director, Nandha Moodley, who is one of the most experienced pioneers in the South African Rubber and Polyurethane Roller industry.

He has been active for 29 years, having started his career with Durban-based Rubber Rollers when it was the only roller company in the country.

Given his wealth of experience and exemplary service to the industry, Nandha opened the doors of Premium Rollers in 1999.

After establishing exceptional success in the roller industry for several years, Premium Rollers merged with a leading European entity in 2007.

Since it’s inception in 2005 and after subsequent strategic transitions and expansion, Rubber Engineering merged with a major Durban based entity to establish itself as the flagship roller covering company in KZN, servicing all provinces in South Africa and the neighbouring countries including Mauritius and Madagascar.

The business and attitude of the management and staff was impressive, and it is obvious that Nandha’s mind has been stretched far by many bold ideas for some decades now.

I took my camera along as I thought I may find some lovely well-used machinery; ideal for some post-processing at home. Unfortunately, I forgot the tripod at home.

I “threatened” Nandha that I would bring the photos of his business to life even though the “bad” lighting and my limited experience was not in my favour.

Nandha can be the judge of that (if I succeeded) when he views the photos below.

The next time you see a magazine, school book or tin can (to name but a few), just think that Nandha’s perfectly manufactured rubber rollers may well have “brought them to life”!

HDR 3 (high dynamic range) final

HDR 1 was rock-bottom shocking (in a funny way)..

HDR 2 was an improvement.

Now (HDR 3) is hopefully the last time for some time that I will use this particular title (HDR).

I am a lot happier (ecstatic) with the results from my mini-expedition today.

For now the photos look good enough for my eye and that’s so important. I’m really hooked baby with these “comic book paintings” of mine!

Jayden Miller’s post on HDR, which I read before going outside, gave me just that little bit more info that I needed.

Trey Ratcliff and Photomatix website had already given me a good foundation.

Let me know which one of the following photos you like if any.

Once again, any criticism together with advice on how to improve will be appreciated.
