Image Forensics : Error Level Analysis

Error level analysis (ELA) works by intentionally resaving the image at a known error rate, such as 95%, and then computing the difference between the images.

If there is virtually no change, then the cell has reached its local minima for error at that quality level.

However, if there is a large amount of change, then the pixels are not at their local minima and are effectively original.

Blending Exposures in Photoshop by John Williams

One powerful advantage of the modern digital darkroom is the ability to expand the camera's capability by blending multiple photographs into a single image.

By blending photographs, you can increase the field of view and/or resolution (stitching), remove unwanted elements, reduce noise, increase the depth of field, and increase dynamic range.

Whether you blend using an automated program or by hand, no one method will work best in all situations.

Automated blending programs can be simple to use, time efficient, and produce optimal results with some images.

Unfortunately though, there are many images where the results are less than optimal.

Although blending by hand can be more labor and skill intensive, many images look more natural with this method.

Jeff Wall: The Complete Edition by Guy Lane

Conventional wisdom has it that large-format, tableau photography - as embraced by many of the most prominent art photographers of recent decades - is a means to fictional ends.

That is, it stands opposed to factual modes of reportage and documentary, for example.

But the work of Jeff Wall, one of the most successful photographers working with staged tableaux, undermines and obscures such demarcations and divisions.

Michael Paul Smith - Photos of my models

What started out as an exercise in model building and photography, ended up as a dream-like reconstruction of the town I grew up in.

It's not an exact recreation, but it does capture the mood of my memories.

And like a dream, many of the buildings show up in different configurations throughout the photos.

Or sometimes, the buildings stay put and the backgrounds change.

Meditations In Black-And-White by William Neill

I recently had a client ask to see some images—black-and-white nature photographs for a corporate environment.

Since I haven't made black-and-white photos at all during my career, except on a rare occasion, I was surprised.

However, her simple request led me down a path that was both creative as well as successful in terms of business.

Crafting Your Photography Website by Kenn Leonhardt

You've spent months and years honing your photography skills, yet the odds are that the majority of your photos sit on your hard drive, doing nothing.

You should change that!

Unless you're a technophobe or that mysterious closet-photographer who doesn't want anyone to see your photos, why not upload your photos to your own photo website?

Setting up a website is as easy as ever and it offers an excellent way to share your photos, while also potentially generating some sales.

On a different wavelength: 100 years of infrared photography by Phil Coomes

This year sees the 100th anniversary of the first published infrared photograph.

Though there had been infrared spectrograms produced before 1910, as far as we know the first infrared images in print were taken by Professor Robert Williams Wood and published in the October 1910 Photographic Journal of the Royal Photographic Society (RPS).

Russ Martin by Michael Werner

My father loaned me one of his Rolleiflex cameras, showed me the basics, and I was on my way.

Once I started, I was hooked. I loved looking through the camera and took pictures of everything and everyone.
