Infrared Camera Update

Posted on


Shot on my new GX1. This camera appears to be better than my old one. I don’t know why but the results are better.

A few blogs back I discussed my desire to have a digital Infrared camera and weighed up some of the options I was considering as a light weight photographer. The usual approach of photographers converting cameras to IR seems to be to take an old DSLR that they would otherwise sell and have this converted. However the cost of this conversion (certainly in the UK) makes me think this isn’t cost effective and anyway, I don’t like carrying a DSLR around never mind a second body for my system.

In the end I decided to purchase a second GX1 body for the conversion. This was not an easy decision and for a while I toyed with the idea of purchasing a GF1 to convert. What put me off was the cost of the conversion was £250 + VAT (ouch) and I would still have an old 12Mpixel camera. Weighing up the cost of the conversion and the cost of a new camera I thought the GX1 made much more sense.

My initial search for a GX1 was looking for a new model at a good price. This would have cost me around £300 after the cash back offer Panasonic was running (that’s a fantastic price for such a great little camera). I also looked on eBay but most of the imported models were about the same cost. I did find a second hand model for sale but the owner had stuck faux leather on the body and I wondered what that might be hiding.

In the end I found a reconditioned model which had a 12 month warranty and had been reconditioned by Panasonic. The price was just £250 and when it arrived it was like a completely new camera. In fact I can’t believe it has ever been used and all the accessories such as the strap were brand new. Best of all the body is silver and my existing GX1 is black. This will allow me to distinguish the IR camera from the standard one.

Now here is where the fun begins because I decided to send my current GX1 for the conversion given that it was about 8 months old but the new camera now had a 12 month warranty. What happened next has taken me a bit by surprise. When I have been using the new camera I could swear the sensor has a much better dynamic range. Quite often I could shoot without an ND Graduated filter where it would have been needed with my older GX1. The images also appear cleaner and the colour more balanced. I did check the firmware but it was v1.0 as was my old camera.

This experience has lead me to conclude there could be a few possible causes for what I am seeing:

  1. I’m seeing things that aren’t there – but I don’t think so
  2. My first camera could be a poor model or my new one could be a fluke product that is better than the average. I recall Ctein writing on The Online Photographer site about his old printer being much better than a new model and after much testing and input from Epson concluding his old model was so good because of exceptional luck.
  3. Could Panasonic be improving the GX1 bit by bit by including new sensor developments as they become available? This is not as odd as it sounds because they are developing new sensor improvements for newer models all the time. Why go to the cost of manufacturing different sensors of different quality if they are all the same size and probably all cost similar amounts to make.

Anyway, I have rambled on for a while here without telling you where I sent the camera for the conversion. In the end it was ACS in Norfolk because I wanted to keep the camera in the UK. I did consider sending it to one of the leading converters in the US but in the end I wanted to support a UK company and after all costs were factored in there wasn’t too much difference. Once I get the camera back and have a chance to use it I will post some thoughts about the conversion.

My Photoshop Skills are Obsolete

Posted on


This image shot on a 5D was enhanced in a mater of minutes using Viveza. The same results in Photoshop would have taken far longer.

For a long time now I have been a user and enthusiast for Photoshop. I am however a strong advocate of making photography light weight in all respects and that includes post processing images. I don’t want to be sat behind a computer for hours on end when I could be out taking pictures. No, my life and time are far too valuable for that and this was one of the drivers for me switching to Lightroom. I had reasoned that Lightroom could give me similar results to Photoshop but perhaps, from everything I had read, much faster.

Well, Lightroom is faster, especially where you want to apply the same adjustments to a group of images. It also makes finding an image a breeze and I wouldn’t be without it now. It is not however a replacement for Photoshop and I find that images adjusted in Lightroom still need some extra “polishing” in Photoshop in order to reach their best. It’s not therefore the huge timesaver I had hoped for.

What has caught me completely unawares however is a Photoshop plug-in from Nik Software called Viveza. It’s a very simple application to use and is accessed from within Photoshop but also integrates with Lightroom. What this plug-in gives me is the ability to make key adjustments to my images whilst targeting specific areas. For example I can edit the blue in a sky whilst leaving the ground and clouds unchanged. Yes I could do this in Photoshop but it would take some delicate selections to ensure I did this with a seamless blend, all of which takes time. With Viveza it takes just minutes, looks completely natural and requires much less skill than with Photoshop.

Having now used Viveza for a couple of months through Lightroom I am finding I do less and less in Photoshop. In fact, it’s got to the stage now where I think I can achieve better results with Viveza than I can using Photoshop. My Photoshop skills, painfully built up over years, now seem largely obsolete.

Panoramic Photography with Lightweight Cameras

Posted on


6 images from a GF1. Shot in RAW and stitched in Photoshop. Technology is amazing.

Recently I realised there was a feature I was missing from the Sony NEX camera that I sold last year. This is the sweep panoramic where you simply sweep the camera horizontally or vertically to produce a panoramic when taking the shot. I thought this was a great feature and one that I could have used when shooting the Ribblehead Viaduct in an earlier blog. My friend who had an iPhone with him at the time had this feature and I now discover I have something similar on my Samsung phone.

To be fair, the Sony Sweep Panoramic dealt fine with large detail but if something had lots of small detail like rocks in a landscape, it didn’t always work well (again, covered in an earlier blog). Additionally if you didn’t move smoothly or in a straight line you could get some strange results. It complained when you moved too fast or too slow. Worse still, if the subject or you were moving, well you probably needed to forget it. I’m actually starting to wonder why I miss it so much!

Now, some of the cameras I use also have a Panoramic Assist mode, for example where they show a faint version of the previous picture overlaid on the camera LCD to help you line up. Again this isn’t perfect and I find it slow to use which means it might not be suitable for many situations where you need to act quickly. The only real solution to this is a true panoramic camera such as my Xpan but then I am back to shooting film which I don’t always want to do.

If you are a RAW shooter and you want the best quality possible, you will need to shoot individual images and then stitch them in software. That’s exactly what I did with the image you see above. This is a series of 6 images shot in RAW using a GF1. I shot the images from a moving boat when passing this particular island and the angle of coverage is about 160 degrees. Quite an extreme set of circumstances to shoot panoramic and one where speed was the key.

If you are wondering how I lined up 6 images so quickly (the boat was travelling quite fast), I used the cameras gridlines. On all my cameras I have the gridlines turned on that divide the screen horizontally and vertically into 3rds. I make a mental note as I shoot of where the vertical grid line is on one side so that I can move the camera to align the vertical line on the other side when shooting the next image in the sequence. This ensures I overlap my images about a third which is ideal for putting through stitching software such as Photoshop’s “photomerge” function. The horizontal gridlines also allow me to judge easily if I have moved the camera up or down.

This takes a little bit of practice but shoot around 20 such sequences and you can become incredibly quick. The image above is 10” x 36”, shot in RAW and could be printed at double this size with some interpolation. The stitching is spot on and there were no telltale joins. I could never have achieved this with any other method

Excellent Lightweight Travel Tripod

Posted on


This image was taken on a 5D MKII. This is not a light weight camera but the Tripod was the lightest I have used. Read on to find out more.

My recent Light weight photography has been a little unusual in that it has required me to use a tripod. Ordinarily I can get away without a tripod as I can shoot with a wider aperture because of the GX1’s greater depth of field. In fact I recently mentioned that I had trouble slowing the GX1’s shutter speed to blur water motion and ended up buying a 4 stop Neutral Density filter.

Now I’m sure if you have been involved in photography for more than a few months you will have purchased a tripod. I will also push my luck and suggest that the tripod falls into one of two broad categories:

  1. The all in one tripod which is very lightweight, has a head attached that can’t be removed and tends to be cheap. These are the typical first tripods people tend to buy often because they can’t see the value in a more expensive make. They also tend to break easily but before they break they are incredibly frustrating to use. I will refer to these as amateur tripods purely to distinguish them from my description of the next category.
  2. The professional class of tripod will be quite different from the above. It will comprise a separate head and legs for which there are a number of different designs and manufacturers. The head will tend to have a quick release plate for fast attachment or removal of cameras. These tripods are far more sturdy and reliable as well as being easy to use. A good one will last years and will probably set you back quite a bit of money.

Any serious photographer will I’m sure gravitate towards the second professional class of tripod. The only problem is that these seem to be larger tripods that are HEAVY. Sure you can get carbon fibre tripods if you have deep pockets and by the time you have attached a head they are still HEAVY. Worst of all, if you want to travel with your tripod most are too large to fit in your case as well as being too HEAVY.

About a year back I came across a solution to the problems of size and weight that surprised me. The tripod legs were made by Velbon (it’s a Rexi L) and the head is made by Manfrotto (it’s a 3 way pan Magnesium alloy). Paired together these weigh less than most carbon fibre legs. More astonishing still is that the tripod legs are about 30cm when collapsed yet extend to be a full sized tripod – this is also my ideal travel tripod. And did I forget to tell you about the very reasonable price for this kit. I paid less for the legs and head on Amazon than I did for my full sized Manfrotto legs (which aren’t even carbon fibre).

What really surprised me however is that Velbon was the manufacturer. You see they tend to make a lot of tripod that fall in the amateur class but the Rexi L is completely different. This clever size trick is achieved by having multiple section legs which often makes tripods unstable. No so the Rexi L which is very steady and supports my 5D no problem. My friend who also has one of these uses it with his Medium Format kit.

Recently I had cause to use my Manfrotto 055 side by side with the Velbon Rexi and I was shocked to find the Velbon was steadier, easier to use and I preferred it. In the end I left the Manfrotto in the car and just used the Velbon. So if your current tripod is too large or just too heavy take a look at the Velbon Rexi L. The links to Amazon are shown below.

Micro 4/3 or LX5 Infrared

Posted on


This image shot on a Sony NEX5 has been converted in software to give the appearance of being shot in infrared

As I mentioned in some of my recent posts I have just been up to Whitby with a friend. These trips are great as we talk about all things photography including quite often the new equipment we would like. It was during one of these discussions that I had to admit I would really like an infrared camera. In the past I might have sought to purchase an old DSLR and have this converted but that wouldn’t fit with my new lightweight approach.

After a lot of consideration and debate I think I have two choices. The first would be to purchase and convert an LX5 whilst the other would be converting a micro 4/3 camera. To be honest, I would love to have an infrared LX5; the lens is excellent and the camera fits in my pocket. What puts me off is that I have heard the LX5 suffers from hot spots under some conditions. I would hate to have an otherwise great image ruined by this so I am loathed to go down this route.

Realistically then it’s probably down to a choice of which micro 4/3 camera to purchase and convert. If I chose the GF1 I would worry about the age of the camera and the cost of the conversion in the UK is about twice the cost of the camera. Alternatively the cost of a new GX1 is now down to £315 after £50 cash back. This seems to be amazing value for money but I still need to find a conversion service that has a good reputation.

Now if you are reading this and wondering why I am not doing my Infrared conversion in software, it’s because it’s very difficult to create a realistic effect without introducing a lot of artefacts around edges in the image. It’s very difficult to get just the right look and to be honest I would rather have a converted camera that I can snap away with.

You will hear more about this in the future as I have convinced myself I need an infrared camera.

Sony NEX5 Sweep Panorama

Posted on


This interior of a shopping centre in Milan was shot using the Sweep Panorama of the Sony NEX-5

I have discussed on this blog in the past how I sold my NEX5 because I wasn’t happy with either the range or quality of the lenses. These factors were very important to me so I’m not saying the NEX5 is a bad camera. Quite the opposite in fact and there is one feature in particular that I deeply miss and that is the Sweep Panorama.

This is the ability to shoot a panoramic picture by simply releasing the shutter and moving the camera slowly and smoothly in a given direction. The camera takes images in quick succession and then stitches them into one long panoramic image in camera to produce a final JPG. If you have never used this feature I can assure you it is very addictive and makes shooting panoramic much easier than shooting and stitching multiple images in software. What has suddenly made me nostalgic for this feature was my recent trip to Whitby where my friend was using his new Sony camera and I would regularly hear the tell tale clicking shutter of the sweep panoramic.

With this in mind I decided to review some of my old sweep panoramic images such as the one shown above. Now whilst I am raving about the sweep panoramic there are a few limitations you need to be aware of – at least in the NEX5 at the time I was using it.

Firstly you need to set up the camera with the direction of sweep. Is it left to right, bottom to top or the reverse of one of these? This can take time and sometimes you don’t have the camera ready at just the moment you need it.

Moving subjects can be difficult to capture. Imaging you are standing on a beach and photographing a wave coming in. The wave will have moved slightly between each shot and the stitching usually couldn’t deal with this.

Moving elements in the scene pose a real problem for the Sweep Panorama

Finally there was the problem with stitching fine details which was magnified further when using a wide angle lens. Take a look at the sample below which shows this problem.

The in camera stitching also struggles with fine detail. Take a look at the figures on the wall closely and also the right hand window. None of these quite align properly.

This can of course be overcome with some work in Photoshop however I would rather avoid this and have a finished image where possible.

On a final positive note, the Sweep Panoramic seemed to overcome the problem with soft corners (although this may be due to in camera cropping).

For now then I will still have to lust after the sweep panoramic mode and continue to stitch my images in software.

Taking My Own Advice

Flowing water and rock shot on a 5D MKII. This isn’t a Light Weight camera

I had an interesting weekend, making a photography trip to Whitby with a friend. Initially we went to shoot the coastal scenery but by 11:30 the sun had become so harsh in the clear blue sky that all attempts at Landscape Photography were thwarted. At this point we sat down, had a coffee and decided to switch our attention to nearby woodland where we knew there was a waterfall.

On arrival we could see the main fall some 80 feet below our path and down an inaccessible cliff. We knew that the falls must be accessible though as we had seen some pictures of it shot from the river. Walking along the path we found a trail that lead down to the river and then a further footpath leading back along the river to the falls. Neither of these paths was easy to walk as the one down to the river was extremely steep and muddy and it took all our efforts to stay upright. The path along the river was even worse, being very deep with mud that came over the top of your boots. Hopping between branches of fallen trees, rocks and tufts of grass was all we could do.

As we made our wall to the falls we came across a large tree that had fallen across the river, blocking it and a steady stream of water was cascading over it. This is the image you see above and it was shot on a Canon 5D MKII. The reason I tell you all this is that despite having my faithful and very light GX1 kit with me I insisted on taking the 5D. I also took a full set of Lee filters, a very large tripod and a large bag filled with all sorts of accessories that I didn’t need.

The result is a nice image but also a hard fall against some rocks as the weight of my bag caused me to slip, overbalance and graze my right hand quite badly. I feel confident I would have avoided this and still have achieved the shot had I left everything behind except for my lightweight kit. I need to listen to my own advice.
