Ballarat International Foto Biennale Photography Exhibitions Review, Part 1

The Ballarat Foto Biennale is a month long festival of photography that is run every second year. Last time it was the Daylesford Foto Biennale (DFB) but the City of Ballarat came on board for this one and, hopefully, into the future. The BFB consists of an extensive number of exhibitions, comprising a core and a fringe collection, as well as a workshop series.

The GigaPan Epic Review, A Motorized Panorama Platform to Create Stunning Photography

The GigaPan Epic automates the shooting of panoramas and photo mosaics. In this review we cover the unit itself and the free stitching and uploading software that is provided. A panorama allows you to capture a much wider field of view than your camera and lens can do in one image. A photo mosaic uses many overlapping images shot in a grid pattern to produce images of much higher resolution you’re your camera is capable of.

Pentax K200D Digital Camera Infrared Performance

We test the K200D for infrared photography using a Hoya R-72 filter.
The K200D is a popular camera with a good range of features at a keen price. For infrared testing we used a heavy tripod (Manfrotto) and a Hoya R-72 infrared filter.

1.    When shot using Auto WB and an exposure of 100ISO, 30 seconds and f5.6, the resulting image (using default ACR settings) has a well exposed red channel, while green and blue are underexposed and a strongly red image.

2.    Adding a stop of exposure (100ISO, 30 seconds and f4) overexposes the red but has not brought the green up enough. There is thus roughly a two stop exposure difference between the red and green channels with the K200D

3.    The red channel of the first exposure has excellent tonality and, with a little work in ACR before taking it into Photoshop has no white clipping and a lovely tonal range.

4.    The green channel of the second image is not as well exposed but, as we will see, can be worked to produce a good image.

If we compare the above two you will the classic difference in tonal placement between the red and green channels because of the deep ir that is captured through the green channel. To understand this see the article Shooting Infrared Photography Step By Step.

The K200D is prone to light leakage through the eyepiece during long exposures. So you will need to cover the eyepiece fully when shooting IR.

Lastly, you can create false color images with the K200D by doing individual levels to each channel and then a red/blue channel swap.

The K200D is a quite capable IR camera, so long as you can handle the long exposures. Full sun exposure for the red channel is around 100ISO, 30 seconds and f5.6, whilst if you are exposing for the green channel you would probably want 100ISO, 30 seconds and f2.8 as a starting point for your experimentation.

Lensbaby Composer Sweetspot Tests with Various Optics, Infrared

We test how the Lensbaby Composer responds with varying aperture and with each of the optics in infrared light with a converted Canon 350D digital camera.
As part of our ongoing testing of the Lensbaby Composer, we test each optic with each available aperture. For this test we used a Canon 350D converted for infrared photography with an internal R-72 equivalent filter.
