Hyper Jeff - Mac Apps Galore

Got a mac, need an app ? Look no further than here.

Hyper Jeff

If you enjoy sifting through lists of new and wonderful applications sorted by type, category and licence, ie freeware, shareware, paid etc then this is the place for you. I've been using Jeff's site for years now to unearth many marvelous pieces of software. Go have a look and see what you can find, just use the 'pick a category' drop down and start trawling.

Esoteric Photography, Alchemical Art.

I've been looking into alternative photography recently, more specifically, making prints using unconventional techniques. It's a practise that lies somewhere between photography, painting and printing. It utilises archaic chemistry and modern technology (and the sun), to create haunting images with unpredictable and deeply atmospheric qualities.

For example, 'digital negatives' are a kind of reverse engineering of digital photography whereby a negative is created from a digital positive. The process is fairly straightforward. Here it is very briefly.

a. Take a digi image you like, bung it into photoshop reverse it, make it monochrome and tweak the levels to adjust mid-tones and contrast, some practitioners recommend giving it an overall orange hue for reasons of tonality in the subsequent creation of a positive (See links for detailed processes.)
b. Print out the image on a sheet of A4 inkjet/photocopier transparent film so that you have a nice big A4 negative.
An interesting variant of this is to print the neg on regular paper then use oil or wax to make it transparent, this yields even spookier soft edged images.
c. Exposeyour neg on your treated paper out in the sun or some other UV source.
d. Give it a wash to develop it and see what you've got.
e. Of course you don't even need a negative, you can instead create 'photograms' by judiciously placing objects directly onto treated paper and exposing as normal.

Cyanotypes (cyan) and gum bichromate prints can be developed in plain old water or helped along with vinegar or perroxide solutions, it's all about experimenting.
You can even go on and use tea or coffee to add further tones to the prints. Some of my favourites I've seen so far are cyanotypes washed in tea, they look great because the vivid blue is really toned down.

You'll need the appropriate chemicals but luckily they are readily available and pretty easy to mix. Alternative photography processes are in use by lots of artists these days and you can find tons of info on the web, but to save you time here's some useful links I've discovered on my trawlings.

I really like this guys work on flickr and there are lots of other esoteric photo printers on there, such as this group dedicated to digital negatives

go forth and create images in your own likeness

HDR Imaging....Tasty.

What the hell is HDR imaging?
Well, I liken it to what mastering engineers do to audio tracks before they go on a cd. They add the gloss, sheen and sparkle, saturate the loudness levels and even-out all the lumps. A similar mastering process happens to video and film in post-production where engineers do magic to the colour balance, brightness and general look of the material and ensure it adheres to broadcast safe parameters, before going to press.

HDR stands for 'high dynamic range'. In music mastering, a thing called the 'dynamic range' is an important factor in preserving the 'light and shade' in the music (a big problem in today's uber loud cd production strategies where dynamic range is severely comprimised). In visual terms it's kinda similar and employs a technique called 'tone mapping' which seems to give digital images an almost eye popping hyper-realism, probably approaching something akin to what you really see with your eyes, rather than the flat tonally subdued images reported to you by a computer monitor. Here's another example.

The great thing is, you can process your own images yourself with the help of a programme called photomax and a quick tutorial (see below).

The images above were created by a jolly nice fellow called Trey Ratcliff and feature on his famous travel photography blog 'Stuck in Customs' which is also home to a great 3 part HDR tutorial here. Thanks Trey.

So there you have it, I haven't done any of my own HDR's yet but maybe soon I will.
