Then and now

Photographs

Group vacations.

I was reminded of a picture I took in the early seventies when snapping this yesterday:

Japanese tour group, 2011. G1, kit lens @ 18mm, 1/2550, f/3.9, ISO 320

Here’s the earlier version, from the Tower of London:

Japanese tour group, 1974. Leica M3, 35mm Summaron, TriX.

Not much changes. The same unity of focus, the same group mentality, the same adherence to instructions. Nice people, though. Had the big earthquake been in San Francisco, the headlines would be replete with tales of looting and theft. All we saw in Fukushima was peaceful cooperation, courage and decency,

Another fine Photoshop CS5 book

Software, Technique

Evening again.

I made mention of Martin Evening’s fine photography and technical writing when I looked at his Lightroom 3 book a while back. Having just upgraded from Photoshop CS2 to CS5, I favorably commented on Richard Harrington’s book recently. It excels for its author’s clear language and an abundance of videos, even if the definition in those is sorely lacking.

Given my previous experience with Martin Evening’s work I went ahead and splashed out on his CS5 book. By contrast to Harrington’s it’s more print than video; the quality of the videos is simply outstanding and I only wish there were more. His video on masking and replacing the background in a subject is so well done that I tried it with a couple of my own snaps and the instructions worked perfectly first time. The chapters are color tabbed so that you can jump to what you want with ease, and taking this large work in bite sized chunks is, I find, the way to learn. It took a couple of decades to get PS to where it is to day, so no one is going to learn it overnight.

I find I tend to watch the Harrington book videos on my TV whereas I tend to sit at the HackPro and work my way through the Evening examples. Like Harrington’s, the book comes with a DVD replete with pictures and videos.

Recommended. And I have to go back on what I wrote about the LR3 book; it’s far easier to use a paper copy than an iPad version. It’s just easier to look things up in a book.

Small sensor noise

Technique

Working with the G1.

In addition to avoiding the Nazi guards trying to enforce a truly moronic ‘No Photography’ rule at the de Young Balenciaga show, I had to contend with camera shake and noise from the Panasonic G1’s small sensor which, even cranked up to ISO 1600, was resulting in long shutter speeds. While the OIS in the kit lens helps greatly, adding two full stop’s worth on the shutter speed front, it’s still all I could do to get a half decent image in the low lighting used at the show. The 1/10th shutter speed in the images below figures to probably an effective 1/40th as regards camera shake with the benefit of the magic that is OIS anti-shake technology. The 28mm (FFE) focal length used also helps, adding a further stop compared to a 50mm standard lens, so that 1/10th makes me look a lot better than I really am, figuring to an equivalent 1/80th or so with a 50mm lens and no OIS.

You can see the original snap which I am talking about here.

In the following images I show enlarged screen shots from Lightroom 3 which are equivalent to a 30″ x 45″ print, meaning huge.

Here’s the first snap with only standard sharpening applied on import of the file to Lightroom, meaning 100/1.1/64 which I find optimal in counteracting the anti-aliasing filter in the G1. Noise reduction in LR3 was set at 0:

Luminance noise is clearly visible though I also have a 13″ x 19″ print in front of me, made on the HP DesignJet90 printer on HP Premium Plus Satin paper (the textured surface tends to mitigate noise to some extent compared with glossy paper) which is perfectly fine unless you stick your nose in it.

In the next picture I applied the following settings in the Detail panel of the Develop module in LR3:

Anything much over 50 on the Noise Reduction – Luminance slider results in artifacts, and falling definition, so it’s a juggling act between noise reduction and sharpness.

The bottom line is that, even at ISO 1600, the small MFT sensor in the Panny can more than cope with noise at any reasonable reproduction ratio for your images. And, as I wrote here, anyone knocking the Panasonic kit zoom as a piece of plastic junk is simply clueless and would likely be better employed telling innocent patrons not to take photographs at costume exhibitions.

To get an idea of the relative size of the Micro Four Thirds sensor (same as Four Thirds – circled) the following image from Wikipedia tells all – it’s approximately one quarter of the area of a full frame sensor as found in the costliest DSLRs:

Incidentally, with the near-grainless sensors in full frame 35mm DSLRs it’s very hard to make a case for the extremely costly medium format DSLRs from the likes of Hasselblad (made by Fuji), Leica with their S2 and others. The gear is far heavier, the lenses bulky and the cost exorbitant, not to mention having to cope with huge file sizes which will need superior computer gear to process efficiently.

No looking back

An interesting exchange with a reader.

A friend of the blog left an interesting Comment/question the other day which I was pleased to debate. Absent a digital point-and-shoot, Michel is still largely a film user of all formats from 35mm to 4″ x 5″, with Leica M6 and R hardware as well as a Hasselblad 501. He’s thinking about a G series Panny for the same reason I took the leap – small, decent sensor, good lenses. Our exchange is repeated below, with Michel’s permission.

The M6 – an exemplar of the last generation of film cameras.

Michel – interesting question.

Full frame cameras:

First I cannot go back to a heavy full frame camera owing to wrist and back pain. Second, I cannot adopt an M9 owing to absence of autofocus and silly pricing. Lenses have a decent life expectancy, sensors do not, so $7k for an already obsolete sensor fails my basic test of economics and useful life. Case in point, I took a beating on the sale of the 5D whereas all my Canon lenses sold at 80-90% of my cost of 5 years ago.

Until/if FF cameras get much lighter, I have no interest in one. Equally, had you told me five years ago that I would be selling the 5D for an MFT sensor (which did not exist at the time) I would have laughed. So ‘never-say-never’. The design genius residing in Japan is quite capable of crafting a Full Frame body which takes a series of compact, high spec lenses and has a superb EVF which is, even in the G1, superior to anything on any Leica RF in poor light. However, if the Japanese continue to perceive there is too small a market for those, we will never see one. Great design and consumer demand/profits are not the same thing.

Small sensors:

I expect small sensor cameras to only improve over the next few years. Case in point, tests (not mine, as I have yet to try it) suggest that the second ever sensor made for MFT cameras (all Panasonic and Olympus models have used the same sensor until now), the one found in the costly Panasonic GH2, is noticeably better than the original model in the G1, EP-1, etc. I wrote off the MFT format when it was introduced and I was dead wrong. (Well, I did call the iPad right, buying two on the first day!)

The most used camera:

I just read today in MacWorld that the most used camera on Flickr is about to be …. the iPhone4. So I am not alone in wanting small, light and take-it-with-you-without-excuses gear. Interestingly the big body DSLRs seem to be peaking, looking at the chart below.

Cameras and trucks and prints:

A while back Steve Jobs said that the desktop PC (and, by inference, the traditional laptop) will become the ‘truck’ of the computing world. It will be a limited use, special tool for the few power users who need it. I believe the full frame and medium format digital cameras of today are already heading in the same direction. Those who need big enlargements will continue to justify putting up with the bulk, weight, noise and cost of the gear. But given that even the cheapest point-and-shoot more than adequately fills a 50″ LCD screen at home and with a little care will yield 13″ x 19″ enlargement (the maximum the ‘prosumer’ printer can do) and that paying just a little more gets you an excellent APS-C Nikon/Canon or MFT Panny/Oly which can scale to 18″ x 24″ paper prints without too much difficulty, who needs more? How many prints larger than that does the average consumer have at home on the wall? I would bet none. There’s is a growing case to be made for the argument that the traditional photo print is, in fact, dead.

One size fits all:

You make the valid point that Ansel Adams might not be the right candidate for a small sensor digital. Agreed. His descendants will happily continue using trucks. And you don’t need me to tell you that ‘One size fits all’ seldom works. Choose the right tool. However, given my avocation for street snaps and the occasional studio portrait, rather than the other way around, MFT works fine for me and I’m sure if I did the research there are some APS-C bodies every bit as capable. Pentax is a master at miniaturization and has produced some nice small APS-C bodies and lenses. Let’s hope that overpriced baubles like the Fuji X100 (yes, I am on the waiting list!) will spur the big boys into competitive action.

Hidden Alcatraz

Book reviews

Book review.

Click for the book on Amazon

This slim book of some ninety photographs presents a current documentary on the cruel, decaying prison on Alcatraz Island in the bay of San Francisco. Cruel in so many ways, from the views of both the Golden Gate and Oakland Bay bridges, from the sounds of freedom wafting from the mainland on the prevailing wind, for the views of America’s most beautiful city so close yet out of reach. It’s as if it was located to enhance the suffering of the inmates for some sadistic purpose, purportedly in the service of man. The Constitution forbids cruel and unusual punishment and while there’s no excusing the actions of those who ended up in Alcatraz, there’s even less excuse for the sheer brutality of the concept.

Clint Eastwood starred in a fine movie Escape from Alcatraz which speaks to the only successful escape, by three inmates, which shows well the inhumanity of the place. Short, sharp and well acted by all, it’s an excellent companion piece to this book, whose Foreword by Peter Coyote is startlingly well written. What sort of person has it in him to become a prison guard, let alone a governor of such an institution?

This book has current pictures, many of which show the merciful decay of this horror story, and contains many memorable images. Perhaps the most poignant is also the simplest. It’s by Peikwen Cheng, appropriately enough a resident of a prison to over one billion souls, and appears on page 40. Titled ‘Days Go By’ it shows the scratches made on a cell wall by an inmate, counting the days of his incarceration. Nothing could be simpler or more powerful.

A mix of well reproduced color and monochrome images, the book is recommended if you like atmospheric photography with a message.
