Retinex Sepia Photography at Nobbys Beach
Digital Camera: Canon NB2LH
Accessories: Newcastle Batteries
Location: Nobby's Beach

I really enjoy the rendering effects of Retinex. It seems to improve visual rendering where there is not a lot of sunlight, which was the case on this day.
While our eyes are able to still see a good range of colours, even in low light, your average digital camera is not so sharp. Using an MSRCR (MultiScale Retinex with Color Restoration) algorithm, which is at the root of the Retinex filter, was created as a result of looking at the biological functions of the humsn eye that enables it to adjust focus and object recognition in poor lighting. And so you have, "Retinex", which is simply a combination of Retina + Cortex.
As well as the Canon NB2LH digital photography, the Retinex algorithm has been used effectively to create visually stunning images in astronomy and is also used in diagnostic imagery for obscure or poorly rendered objects and features in scanners and medical x-rays.
Location: Nobbys Beach, Newcastle New South Wales, Australia.
Considered by many to be Newcastle's best Beach, Nobby's is ideal for a family, and, if it's quiet enough, a geat place to shoot video or stills.
If you want a safe and clean beach then Nobbys beach is for you. We brought a family here tfrom out of town on an overcast day and really enjoyed it. The beach is patrolled by life guards and there are amenities and a cute little cafe right on the beach.
I was once told not to bother taking photo's at the beach since beach shots tend to all look the same.
I thought that, living in Australia, with over 10,000 Beaches, that seemed like a bit of defeat. True, beach photography is challenging, but not impossible to get right. Finding a unque focal point is key. With so much expanse to deal with, it is important to bring the camera in close enough for a viewers eyes to settle on a fixed object or point.
Not only do you need a good focal point, you need to find something unique in the color and contrast of the foreground. In this case, I went back in time to create the contrast and the Retinex effect. I like the results, even if my actual photography skills are only average.
This was taken in the middle of an Australian summer in Newcastle, adandn so light can be a problem as well as teh risk of under exposure in an effort to compensate. We had cloudy day nad for this experoment it gave us just the right amount of light we wanted.
The image above is a little overcooked and the one below could have been closer, but in both I wanted the scene so it was a compromise.
A UV filter is a good idea since it can help correct light and shade. A polarizing filter is even better on some shoots as it will cut down the number of relfections. I didn't use one, but it would have been intesting to see how a neutral density filter might have changed the colouring of the shots close to the waters edge. Thankfully I was able to keep the cameras motion blurr to a minimum.
