I bought a new camera

I was disappointed, that I missed, buying the Canon G10 in 2008, I hunted high and low for it in late 2009, to no avail. I purchased the G11 early this year and, I'm much happier anyway. Noise levels are reduced in this model, according to the specs and the banter on forums like dpreview.com

[From Canon Camera Museum | Camera Hall - Digital Compact Cameras]

Unfortunately due to the awful lighting conditions this time of year, I've not been able to shoot a great deal, to really get some results from it.

Interesting too, note that Canon, list it in the “Museum;” already?

Scanner Camera

I recently began experimenting with alternatives to traditional digital capture. I'd thought about using a scanner somehow to capture images, and some digging around on the interent produced some good results. The main one however, used a simple cheap magnifying glass lens with cardboard apertures and a sliding focus arrangement. I figured I could do better, and with numerous 35mm lenses lying around, I figured I could get something more manageable together. So here's how I made these images.

I used a Canon, flatbed scanner I had lying around, one that I use for low end webscans. I bought some black foamcore, and scrounged up an old 35mm lens.

I cut 4 strips of the foam core to fit the scanner each being 50mm high, and the approprite width and length to fit the scanner. I then cut a piece the same size as the platten of the scanner. This had a hole that held the lens in place. I used the ever useful gaffer tape to construct it.

It took some time to realise that, I had incorrectly calculated the focal length of the lens I'd used. So by modifying the piece that held the lens so that it sat lower inside the 'housing', I had more luck.

Exposure and focus still seemed a little hit and miss, so I set up a studio arrangement, and had more luck, but of course the platten of the scanner is more than A4 in size, which puts it in the realm of an 8 x 10 inch camera, in terms of square area of light capture. This seemed a bit of a waste, and eposures anf focus were stil not at an optimum.

My final experiment was to use a Box Brownie Camera, attached to the scanner, this yielded pretty good results too. Ultimatley though, I'd like to get my hands on an 8 x 10 camera lens, say around 300mm and try to utilise the entire platten.

The last idea came from the scanner project page.

Scanner Camera

Today, I am attempting to build a scanner camera, primarily for use in a class at work but just for my own curiosity, to see what kind of images I can make, I'm also thinking about an article that questions whether digital [onscreen] images can be art?

Camera/s

It's that time of year when, I attempt to coax aspiring photographers away from the 'P', 'A' or 'Tv' settings on their cameras. For many many years we at PIC photographic imaging college used the ever trusty Pentax k1000. Simple, solid reliable, durable [even in student hands] an all round great beginners camera. No clumsy interface, no strange dials, one that could take a photo without a battery even.

When pic first bought a digital camera, a Canon 350d, it was ruined beyond repair in it's 1st year of life. By contrast, most of our Pentax K1000's are more than 15 years old and some are over 20 All still going great guns, even after numerous trips to the the camera technician.

The principles of exposure, depth of field, focus, and good picture making, have not changed. All the controls on a camera I need to teach someone how to make good images, are; manual aperture control, manual shutter control, manual focus, [d.o.f of field scales on a lens would be handy too] a tripod mount, and the ability to add a cable release. I care not whether these controls are electronic or mechanical.

Now, call me an idealist, but surely would it not be in the interests of camera manufacturers world wide to make such a camera? We enrol enough students to employ 6 full-time teaching staff and several assistants and technicians year in year out for more than 20 years. We still have over 30 Pentax K100's in our store, we have associated lenses of several focal lengths, filters UV, and coloured, cable releases macro lenses and close-up re-copying facilities, the lenses are all 'K' mounts .

I dream of a digital camera, that has minimal electronics, shutter aperture and white balance controls and no more, with a "normal focal length lens as standard, with d.o.f scales marked accordingly, with the ability to add a cheap cable release, and of course a tripod mount.

Canon, Nikon, anyone?

... crickets....

Detective work?

unidentified agfa camera

A former student has asked me, for some help. Can anyone help me identify this camera, I can see it's an Agfa, but not the make?

January 10, 2009: Sony's CES announcements include the Cyber-shot G3, which is claimed as the world's first Wi-Fi-enabled digicam capable of uploading photos and videos to web sites through any public hotspot.

The built-in web browser enables the camera to connect wirelessly to free or fee-based hotspots, as well as to secure and unsecured access points.

Moore's Law...

According to the SD Association, a 2 Terabyte SD card is on the horizon.

TWO TERABYTES!!!

SDXC is a next-generation memory card format, with up to 2 terabytes storage capacity and read/write speeds of 300 megabytes per second. SDXC (eXtended Capacity) will provide maximum speeds even when it achieves its maximum 2TB storage capacity. "SDXC is a large-capacity card that can store more than 4,000 RAW images, which is the uncompressed mode professionals use, and 17,000 of the fine-mode most consumers use." said Shigeto Kanda, general manager at Canon. Developed by the SD Association, specifications for the new SDXC standard will be released in the first quarter of 2009.

Geeked Out

Have spent all of today fine tuning and surfing, in the process I've discovered the following:-

  • Safari 3.0 Beta has been released
  • There's Ad blocking software out there for Safari, but only Version 2
  • Several more blogs and links on photography
  • Newswire, and Netnewswire are the two big guns for news reading online.

I also managed to write a simple Mo-phone Manifesto, I'll maybe upload or share it in some way soon.
