Ramped Up

Pressure is mounting for the upcoming solo-show, have collected 2 images from a Pro-Lab, not happy with the 'look' of the prints at all. However, I have been fortunate to have been put in touch with an Art School that prints large format. Had a quick chat last week with the guy in charge of the printing and am now proceeding with 7 inkjet pints 1 metre square.

Now I've just got to find 7 times $140.00!

Outside said art school I found this piece of graffiti, and of course the only capture device I had was a mobile phone, I made 2 images with it and chose this as the best one that expressed the idea.I felt the context from the surrounding Architecture was needed.

Photo Sales

serendipity?

Trying a new photo site, aimed at selling mainly, so not that much use to me, we'll see, already a few flickrnauts moving in.

Fantastic work

Nine is too many

Based on this mock-up, I feel 9 prints will be too many.

1/2 Done

IMGP1471.JPG

I shot the first half of the DOF exercise on Friday. I used a zoom and a fixed lens. Just looking at the lens markings on the zoom confirm yesterday's post.

The second half requires either a portrait or a still life.

The reason we use either a portrait or still life is, because when the subject is closer than 8 times the focal length of the lens the relationship of f/g and b/g DOF changes.

The top image was made using the fixed 50 mm lens, which actually has an equivalent 35mm focal length of about 80mm

Here are the two lenses used, it's interesting to notice that, the Zoom lens made for the Digital camera, has a smaller spread of distances under 1 metre than the fixed lens.

Realisations

Yesterday at work, we were discussing an exercise the students undertake to understand Depth Of Field.

Historically, we get them to take 1 shot at 3 different apertures in one location on a tripod then shift focus and repeat, finally focusing on infinty and repeating again, as well as a portrait at 3 different apertures, on a tripod.

A year or so ago I did this exercise using a Canon 350d, and the differences were NOT as apparent, as a traditional 35mm camera, I left it at that and haven't given it much thought since.

When I mentioned this in the meeting a passionate discussion then ensued as to why this was the case as we are contemplating getting the students to do this assignment using digital cameras. Beginning students need to see big differences quickly and the 350d wasn't giving the results I'd expected.

As a result, we found the answer. It has to do with surface area of the light capturing surface and size of circle of confusion. The smaller the film/sensor area the more D.O.F you have.

Let's let Bob Atkins explain it.

"So the bottom line - and all you really need to know - is that DOF is inversely proportional to format size. Note that format size is inversely proportional to the "digital multiplier". The higher the "digital multiplier", the smaller the format and thus the greater the depth of field. Note also that now you can see one of the reasons large format camera users need tilts and swings to get adequate depth of field. With an 8x10 camera you have about 8.5 times LESS depth of field than you do with 35mm for the same image. This also explains why consumer digicams, some of which have sensors 1/6 the size of 35mm film, have such a large depth of field and one of the reasons why it's almost impossible to get blurred backgrounds when using them."

The difficulty for us to teach the principles of D.O.F is that all cameras have different sized sensors and only cameras like the $4,000.00 Canon have 35 x 26 mm sensors. A camera few students can afford and the type that is not held in stock by us because of their delicateness.

Today I am going to shoot the exercise on the Pentax k100d, which has a larger CCD than the Canon 350d. I may post the results over at flickr, we'll see?

First Print

So yesterday I finally got to print a print on our Epson 2100 printer at PIC. Close very close, some work required, and the profile from, Roy Harrington, is very good straight out of the box.

Pictures to come, seeing as a certain someone has misplaced a certain cable!

The Antithesis Of Phone Cameras

Thanks to Joerg over at Conscientious here's a little movie on the very influential photographer Stephen Shore, and one of my favourite photographers.

His large format colour work of the 70's helped make colour an accepted art form. The type of camera he uses, and 8 x 10 inch, using colour neg/C41, and the approach is at the other end of the scale to the way a phone camera user would work.

More Thoughts On Phone Cameras?

It seems I'm not the only one musing on the implications of phone cameras.

Impromptu Spontaneous Photographers?

I guess if I really thought about it, photographers like Garry Winogrand [his wikipedia entry] and Robert Frank, have helped the cause of the snapshot Aesthetic, I wonder though what Mr Winogrand would have thought of mobile phone cameras, as for Robert Frank, I'd like to ask him personally about his thoughts on the matter?

Phone Cameras?

first publication

So yesterday I posed a question about Phone Cameras and thanks to all who responded. I've got to confess it's was a slightly loaded question, as I said I am thinking about putting together a short course/workshop in Phone Camera use and this is all heading somewhere.

Personally when I am trying to share some knowledge about anything I often try and list a series of pros and cons about what it is I'm try trying to share. And sure enough there has been some additions to the list by my readers.

While Phone Camera's up until recently had such poor levels of resolution, and small storage capacities, the whole idea of doing anything other than sending the photo to another phone user or posting on the web or e-mailing these images, were incomprehensible to phone users. Now with increased resolutions and phone storage capacities their uses are able to be extended, with some provisos.[Avant-garde image makers think differently I believe.]

Remember these are the modern equivalent of the 126 and 110 cameras of the 70's the latest incarnation in the idea that George Eastman brought to the Western world way back in the 1900's. Many many family histories have been recorded using these small cameras, not so many serious bodies of work though?. I am at a loss at the moment to remember anyone who has used a 126 or equivalent to produce a serious body of work however, and I don't consider Lartigue a candidate here as cameras were still in the realm of the wealthy middle and upper classes of the time.

Has anything changed since then that would allow people to make and record their lives differently? Well computers and the internet have impacted dramatically, the way folks capture and share images, these cameras are more than perfect for recording family histories, and small and easy enough to share almost immediately. With most people's expectations of these images are along the lines of, can I see what is important, faces scenery etc, these cameras then serve this function well under the right conditions, outdoors in bright sun for example. They are then able to say to themselves, "I'll send it or have it printed for my Mum/Aunty/Friend".

Such is the proliferation of these small cameras, that no longer do you even need a computer for this, most photo labs, in Melbourne anyway, have the ability to accept all sizes and shapes of memory cards to enable printing from any cameras including phone cameras or accept bluetooth transfers. So already we have the ability to not only electronically share our phone camera images but now print them out using traditional min-lab i.e. small prints.

I believe that electronic sharing of these images is more than enough to justify their use, the proliferation of photo sharing sites out there along with websites interested in the idea of alternative image making means a body of work can be produced and shared easily and quickly with as many like-minded people as you can find. Provided you accept the limitations of these cameras, and plenty of limitations they have.

So what other things can we do with these cameras? Well unless you are prepared to accept great seas of digital artefacts and horrendous lens aberrations, it's highly unlikely that you will be making 1 meter wide prints and exhibiting them, if on the other hand you are happy with a small print there are some other options outside of online publishing. With access to any desktop publishing software and a decent quality printer, you can print your own cards and books thus adding some meaning to the work you are making using these discrete little cameras. Possibly even creating a level of revenue that could justify the time and effort spent on printing them. There are even several online services that allow you to upload and publish, books cards and calendars, to an online store. This is based on the premise of a small book as file sizes are still on the low side to make anything bigger than 6 inches by 4 inches. I guess though, a 4 or 5 mega-pixel phone camera is only months away?

Hmm waffled on a bit today sorry?

Anyway here's my table of pros and cons.

 
Mobile Phone Camera Pros and Cons.
Pro Con
Small, goes everywhere. Small file size/s may inhibit output options, too many choices for the inexperienced.
Discrete, able to be used anywhere the user feels morally comfortable. Certain social situations may not be the right place to make an image.

Able to be sent anywhere anytime.

Costs could become prohibitive, if not used wisely, not supported by all telephony providers.
Instant feedback. Critical self-evaluation of images not encouraged.*
Almost infinite Depth of Field. Poor Lens quality.
Wide Angle lens, wider angle of view than the human eye. Wide Angle lens, wider angle of view than the human eye, requires skillful use and operation in terms of composition.
Zoom is digital. Limited Zoom is digital resulting in high levels of noise.
Unpredictable results, giving weird colours strange movement and noise and blur. Unpredictable results, may not be desirable depending on users aesthetic.
Unpredictable results. No technical controls, f stops shutter speeds etc.
Limited choices means image maker must think hard about how to make a good image, without relying on zooming etc. Limited accessory range.
Can be used anywhere where there is light. Requires ample light, unless user can accept high levels of digital noise.
*This actually applies to all digital camera users and is some ways the most difficult of skills to acquire.

I've been busy in the darkroom of late, but I am starting to think about a new workshop looking at Phone cameras and online publishing, as the new school year looms.

Without my camera phone I could have not made this image, would I have even contemplated making it without my little Sony Ericsson k610i?

Does anyone have any thoughts about their phone cameras [or phone cameras in general], has either of my readers changed their approach to their image making because of them, or are they just a chintzy little tool to be used selectively for a lo-fi grab when a bigger camera is not available?

Well Done to Kent, all his hard work paid off and now according to the Financial review, the show will move to Canberra in 2008

Here's the news lifted directly from the petition site, which by the way you can still sign to show your support for the show.

Katrina Strickland reports that the Australian Photographic Portrait Prize will be reinstated in Canberra at the National Portrait Gallery in 2008. This is great news for all our supporters who have helped bring this competition back. We will be leaving the petition open for anyone who wants to show there support for the new show and Portrait Photography.

Radio Interview

Kent's radio interview on saving the Australian Photographic Portrait prize, should be able to be downloaded from the ABC 702's pod-casting page. The morning show, where Kent was interviewed, may also eventually upload the interview.

If somebody finds a down-loadable pod-cast first please let me know, so I can link to it.

Lousie Swan

Kent, a friend, [and damn good photographer to boot] from Sydney was interviewed by the Sydney Morning Herald recently. He is also being interviewed by Radio 702 at 8:45 am tomorrow, 18.01.2007.

Go Kent, let's hope that the Citibank Australian Photographic Portrait Prize either gets re-instated or picked up by another gallery.

Inkjet Prints

Well Inkjet printing now becomes more of an option, I had heard about a profile or rip that allowed very good control over b&w prints from Epson Printers, a quick e-mail and I found the profile/rip in question. Now I can run my own small tests at least before I make any final decisions one way or the other.

How Fortuitous

Yesterday I talked about where to start with creative manipulations on a print. Last night I found this article on the online photographer's blog, dealing with interpreting print making in a digital era.

Exhibition Preps Week 2

LP screengrab

So begins the creative process of print manipulation. This in some ways is the hardest aspect of all. Where to start? When to stop, are all compounded by digital technologies. At least in an analogue environment you had to make a small test to determine a start time around which all other moves were based. With digital, well there it is on the screen, what more needs or can be done is the question you must ask, and hopefully if you have access to a good printer profile you can "preview" your image and make some decisions in the right direction.

Printing, on the other hand isn't going to be so straightforward? First question, how big? Well I know the answer to that up to 1 metre square. Next question. Inkjet print or Type C print?

Each have their relative merits, Type C prints, are tested for their durability, and being a chemical process are known to last for a certain amount of time, Inkjets are claimed to last as long, but of course this is based on accelerated testing methods, not real life, I have some inkjet prints made in 2000, they are ok but not perfect, unlike all my silver gelatin prints which ARE perfect still some dating back 20 years. The advantage of the inkjet printing is the vast amount of surfaces and materials one can have work printed upon. There are also some very nicely created printing profiles out there, that when used with a particular paper give almost silver gelatin photographic results.

Of course if I was simply, printing largish silver gelatin prints between 8 inches square and up to about 24 inches square, I would use silver gelatin paper. Which brings me back to where I started, and instead of spending my holidays on a computer, I would have been locked away in a darkroom making prints.

Indeed, "Everything in Photography is a trade off".
