Take 2 on my camera considerations

Further to my previous post on camera choices and image processing workflow, I had a change of mind.  I decided to go ahead and buy the small DSLR I wanted (Canon 100D), to replace my rather large and heavy model (Canon 20D), which I’ll sell privately to off-set the cost.

We struck an especially lovely evening in our favourite spot, which gave me chance to test the new camera.

In my defense, there was some degree of rationale in my thinking.  I’d bookmarked the camera at several retailers and as a replacement model has been rumoured, I was monitoring prices, expecting there might be a reduction if a new model was announced – I’d picked up previous cameras at good prices in such scenarios.

I love that taking photographs allows me to notice things that I otherwise might not, like the fabulous structure of this scabious flower.

At one retailer, they suddenly dropped the price a little over 10%, without any mention of doing so and the unit at that price didn’t seem to appear when searching for it independently on their site.  If I hadn’t bookmarked it, I might never have seen that price.  So I monitored it over a few days and it fluctuated several times by odd, small amounts, like 67p.

As it was less than a week until the manufacturers cash back offer was due to end, I decided to go ahead.  It might well come down if another model does come out soon, but I’m still pretty happy, coupled with the cash back offer, that the price was as good as I was hoping for anyway.  As I’m going on holiday soon, it would be a shame to miss the opportunity to take it with me, so the decision was made.

I was actually pretty happy to see that the price went back up again the very next morning, even before mine had been delivered, so my timing had thankfully been spot on.  I have a slight suspicion that the lowered price might even have been a mistake on their part as it made it very competitive.

Having got the rather diminutive camera I have also decided that I’ll probably sell my one pretty decent lens, an ultra wide angle that looked as sexy as hell on my larger DSLR, but is very front-heavy and unbalanced on the smaller body.  That, as such, wouldn’t bother me, but it is wide enough at the front that when you put the camera down, it rests on the wide front of the lens, not the base of the camera body.  I’ve not used it as much as I expected, so selling it, with the other body, might well cover most of this new camera.

Whilst I love my Fuji HS20 bridge camera for a lot of reasons, I’ve always missed not using a DSLR – the gorgeously creamy smooth shots, better detail in features like grass and foliage and especially the great quality at higher ISOs and the speed of reaction, from establishing focus to taking the shot.

The digicams, on the other hand, seem to think about it for a while, then decide if they feel like taking the shot – at least that’s how it feels if you’ve just spotted a barn owl flying past you at eye level 15 feet away, as happened recently.  The tree shot above left is a good example of the lovely lighting I see regularly as we drive along the single track road and have failed to capture many times because the camera couldn’t get focus on a moving target.  I often take photographs out of the moving car window (as a passenger I hasten to add) and the speed of a DSLR is much more suited to this practice.

I have always liked to develop my own images from RAW files (the camera just saves the raw data of the image and you use software to turn it into an image on a computer subsequently) and I like blending exposures from tricky scenes beyond the dynamic range capability of the camera.  Our eye/brain combination is so clever, that a camera is really up against it when trying to capture a dramatically lit scene in an instant single frame, where our eyes scan it rapidly and make complex micro-adjustments that form the whole scene we ‘see’ – complete with details in the fluffy clouds and also under trees, deep in shadow.

The sunset scene above and the banner shot at the top are such examples.  I know that those images now represent how the scene actually was, as the sun set and left the land bathed in the most fabulous golden glow, just before the colour left it almost completely.  It was too dark to see much of the landscape detail within minutes of taking the shot.  It’s a fleeting light show that’s hard to capture and the camera wasn’t able to catch all of that subtlety in one frame, without my help.  It didn’t help that I was trying out auto white balance and it corrected that orange glow for me, rather defeating the object, which is why I rarely use it – cloudy or shade white balance is better for sunsets as it tends to leave the colour largely alone.

I've always been fond of doing wide landscape vistas, with a piece of foreground interest.

What I like to do is develop 2 versions (or more) of an image.  One – as in this case above – to capture the sky as it was and another with more detail of the land, bringing back the detail in line with what I’d seen.  With lighting that dramatic (and it was possibly a bit darker than it might look) it’s not possible to get both looking good in one frame without some post-processing assistance.

I then blend them together in one composite image to get the best of both.  Ideally, if I had my tripod, taking two separate images, one exposed for the sky and one for the land would no doubt give a better result, but this is an intermediate way of getting almost that result.  I don’t see it as any different from dodging and burning in the darkroom under the enlarger, which I’ve also done.  I’m going to try exposure bracketing next time to see if I can get the individual frames close enough on alignment, hand held, for it to work, it might be a good compromise.

On the down side of going out and about again routinely with a DSLR (I’d stopped carrying the other one, purely because of its weight and size), I’m having to re-acquaint myself with the geometry of the much shallower depth of field achieved with the significantly larger sensor in a DSLR.  I’ve got rather spoiled by not having to worry about it, due to the tiny sensor in my other compact cameras and at the moment, it accounts for several less than stellar results with the new camera.  It hadn’t taken me long to stop giving it conscious thought as I worked – a habit I quickly need to re-learn.

It is, of course, also a creative bonus too – allowing the subject to be isolated from the background, like the grass to the right and the deep red scabious flower above, dropping distracting details and texture from backgrounds, or just leaving enough to give the frame context.

But none of this has addressed my earlier workflow concerns, far from it, it has opened a whole new can of worms and the battle continues.  I love working from RAW images, but can’t afford the best software for doing so, so I’m trying to settle on something that will work for me with minimal outlay.  I have two pieces of free software at the moment, each of which has its merits, but neither is an outstanding winner in addressing the way I like to work and the things I photograph. I think this is partly due to my lack of expertise with them.  The software is much more sophisticated and capable than when I first started tinkering with RAW files about 15 years ago, so I see another learning curve to climb ahead of me.

My work this week:

Quite a bit of my time of late has been taken up with working on commissions and re-working older designs that still sell well.  I occasionally re-visit pieces when I come to make them again, to see if the design or methodology can be improved upon and this necessitates the taking of new photographs and re-writing the product description where the item changes.  This can seem as though I’ve not made much, but it’s a perpetual process of keeping on top of designs and ensuring that as my skills improve, so does what I offer my customers, just as it should be.

I do have two new silver pieces from my recent period of working with silver clay:

Appraising camera equipment and workflow

I’ve been thinking a lot about cameras and photography recently and appraising my equipment and image processing workflow.  My photography has meant different things to me at different times in my life, but has been an important constant since childhood.

On a recent walk, we saw Foxgloves that were as tall as I'd ever seen, this patch were as tall as me.

Ideally, I’d like to swap my now rather heavy DSLR for a smaller, lighter model, as my use for it has changed in recent years.  But at the moment, I can’t make the numbers work for me or justify the additional expense.  I was lined up to trade in my heavy DSLR for a lighter modern model, but the retailer concerned reduced their part-ex offer to me at the last minute, so in rather a fit of pique and annoyance, I asked them to just return my old camera to me and took the new camera out of my shopping cart.

I took ownership of a new (at least to me) computer a few months ago and am gradually replacing software for the multitude of things I use my computer for, so image editing processes were important things to consider.

A favourite spot for bluebells, this is an old photograph I revisted in RAW format as it had been overexposed in the patches of sunlight.

Until my last computer got too tired to handle it, I habitually took all my photographs in a RAW format to process later and would never consider buying a camera without that functionality.  But I had more recently started working just with JPEGs – it seemed a better solution with the bridge camera and compact I was currently using as walkabout cameras.

If you’d like to see an even larger version of the bluebell woods to the right, I’ve also uploaded a large version of the file – sometimes with detailed images like woodland, you need to see them large to appreciate the details.  I wish I was there right now, perched on a log with a cup of coffee, a book to read and to just enjoy the birdsong.

But having installed several trials or free programs for RAW conversion, now my computer can handle it, I started looking out older photos from different cameras to test with and it has been fun to tinker with images again.  The program I’ll probably settle on using is so feature-full that it’s going to take some time to learn in order to get the best from it.

Although I have concluded after several days with the programs open and periodically tinkering with them, that I’m still getting better results with JPEGs with the two general purpose walking cameras I’m using, the RAW format files just don’t seem to work as well (almost certainly down to some degree to my own ineptitude) as the cameras own purpose designed processing algorithms.  Whilst I can certainly improve exposure, tonal range and colour, it seems to be at the considerable expense of noise and deteriorating image quality – probably due to their tiny sensors.  So the exercise has been worthwhile, even if what I take from it is ‘as you were’.

But revisiting some of my old RAW files from the DSLR (and the previous model), those certainly do very well.  I’ve got great results even with quite old files with the new apps and have rescued images I’d written off as unusable.

It has however thrown into sharp relief the quality of image that I get from the DSLR (even though it’s a 10 year old model) compared to the newer digicams and made me even more determined to get a smaller walkabout DSLR model.

I’ve salted a few of these recently re-worked images above.  It has been enjoyable, whilst I count down the weeks to some holiday time, to look again at some of my favourite spots as I work on the images.  It’s not quite the same as being there, but for now, whilst we have another summer of unseasonably poor weather, it’s been a little treat.

On the BBC's Springwatch, Chris Packham gave a word of the day and one day it was 'shivelight' to describe shafts of sunlight breaking through woodland canopy - as you know, one of my very favourite things.

This image on the left, of a new path we walked over the weekend, is an example of what I mentioned above about working with JPEGs.  Due to the extremes of light, I took it as a large JPEG and a RAW file together (on my bridge camera) and spent some time trying to get the result I wanted from the RAW file and wasn’t especially happy with the result.  So I opened the JPEG and used my usual workflow and within 5 minutes had got a much better result.  I doubt that would be the case with RAW files from my DSLR, but certainly with this camera and its tiny sensor, I don’t seem to be gaining enough to be worth the effort.  It also trains me to ensure I get the exposure right at the point of taking the image and not allowing myself to be sloppy, knowing I can pull it back in processing, so perhaps this is a complimentary technique to ensure I keep my mind on good camera practice.

When you've had a nice walk, a picnic supper, sat and read whilst listening to the birds, what better way to end the evening than a sunset like this.

I do however have my camera set up to give me the best possible neutral file to work with, knowing that I like to post process my images to my preferred result later in software.  I keep processing parameters to a minimum, like sharpening, contrast and saturation.

This means that my images tend to come out of the camera looking a little soft, flat, dull and bland.  Which is fine by me, it preserves highlights and detail and gives me a good neutral foundation to work with.  This wouldn’t work if I wanted to print directly from the memory card or wasn’t prepared to work on images, but for me, that’s half the fun.  It’s not an approach that most people would wish to adopt, but I see it as a pseudo-RAW intermediate format; the best possible JPEG data is recorded, but it certainly needs to be knocked into shape visually.  So until I can find the pennies for a new DSLR, I’ll use my old one when that’s needed and make the best of what I already have.

My work this week:

I’ve not just been tinkering with photos and thinking about cameras this week, I’ve put in some quality time with some silver clay.  I bought some at Christmas when it was a good price, but this is the first chance I’ve had with the time to crack it out and get something made.  My copper wild rose pendant sold soon after going on sale, so I also wanted to try a smaller one in silver.  I scaled down the component shapes and worked in just the same way as previously, except I replaced the round disc I’d used as a base on the back of the copper one with a proper calyx shape, so that it’s as nice on the back as the front.

I’ve always been very fond of simple, uncluttered jewellery and especially silver with sleek lines.  I wasn’t sure how sleek I could get with silver clay, so this pendant was a bit of a trip into uncharted waters for me, but it worked rather better than I’d hoped.  I also love marquise shaped stones and have had a few put aside for the right design for some time.  I decided that the greater shrinkage rate of copper clay might render it unsuitable for setting a stone with such a long perimeter distance (a lot of distance to shrink and potentially crack), but it worked perfectly in the silver, which I’m finding only shrinks around 5% from dry after firing.
