I’m excited. I have bought a second EM5 body given the recent drop in prices. It’s second hand but has a low shutter count. In fact I didn’t want a new EM5 as I am going to get this one converted to Infrared.

When I had the GX1 converted I used a company called ACS. They did a good job but took an age to do the conversion. This time I have spoken to a company called ProTech who a friend has used for a few conversions.

I hope to take delivery of the camera this weekend and then it’s off for the conversion. I hope to be able to report back in a few weeks time and make some comparisons regarding image quality.

With it being a Bank Holiday in the UK today and for once the weather not being terrible, I went for a walk. I like quite near to the Peak District National Park but for some reason I seldom visit. Today I decided I wanted a good walk in the hills so drove over to Ladybower reservoir which is about 50 minutes from my house.

When I first became interested in photography I remember seeing some old images of the dam at Ladybower and I thought these images were wonderful. The Victorians certainly knew how to engineer wonderful structures but the age of the images also made these more appealing.

I recall visiting the area about 10 years ago in the hope of being able to recreate these wonderful images but it wasn’t to be. Today I was able to create something that I quite liked using my Infrared camera. But it wasn’t until I took the image into Nik Analog Efex and applied a little emotion that the image came to life. Trying to create an image such as the one above was almost impossible for me 10 years ago but today it took minutes.

I wonder what photography will be like in another 10 years.

Infrared Filters

Over the weekend I published my spring newsletter. Those of you who subscribe and who have had an opportunity to read the latest issue will know that the main article explores the options for infrared photography (including some that cost very little). As I was writing this it got me thinking that I wanted to shoot some Infrared film using my Hasselblad XPan which I haven’t used for about a year.

Choices for film are very limited these days so it was either Ilford SFX (which isn’t really a true infrared film) or Rollei IR400. I purchased a few rolls but realised I didn’t have a 49mm Infrared filter for the XPan lens, so needed to turn to eBay. I also realised I had sold my light meter thinking (incorrectly) that I wouldn’t need it again, so ended up needing to buy another.

Anyway, whilst searching for a 49mm Infrared filter (720nm strength) I also had a quick look for an 850nm Infrared filter and found quite a few. For anyone who is unfamiliar with these filters they will block out light with a wavelength shorter than the filter strength. For example a 720nm filter blocks light with a shorter wavelength, effectively blocking visible light but allowing infrared wavelengths through.

The reason for wanting a 52mm 850nm IR filter (which incidentally only cost £10 including postage) was so I could use it with my Infrared camera. When I had the camera converted to infrared I had a choice of having it fitted with either 720nm filter or an 850nm filter. The 850nm filter gives a more dramatic effect and can only be used to produce black and white images. I opted for the 720nm filter as this allows you to create some false colour effects. By using a screw in 850nm filter on the lens it’s like having my camera converted with the stronger filter.

When the new filters arrived I checked them. The 720nm filter made no difference to the IR camera but blocked the visible light from a standard (unconverted camera) so I knew it was a good filter. The 850nm filter when attached to a lens on my infrared camera caused a loss of about 2 stops of light making it very usable for handheld shooting. It also caused a colour shift to blue in the image but this is probably because I didn’t bother setting a custom white balance. The blue tint was easily corrected during the RAW conversion.

Now here’s the interesting thing, when I used the 850nm filter on the infrared camera, although the shutter speed was slower by 2 stops, the image quality was better. I didn’t take sufficient images to check this out properly but across about 10 scenes, the 850nm images appeared to have sharper and finer detail in all cases. I can’t explain why as in fact I had expected the opposite to happen. I’m going to keep a close eye on this as the light starts to get stronger and better for shooting infrared.

As some of you may already have gathered, I love Infrared Photography. It’s much more frustrating than traditional photography to create good images but the challenge makes it more rewarding. It also opens up a new world of seeing as scenes can take on a completely different appearance. Also, when the time of day or weather isn’t great for traditional photography you may find that it is great for Infrared.

Here’s one of my Infrared images that I wanted to share. Captured last March on a trip to San Francisco (wow is it really almost a year ago). The scene is very ordinary and the light was a bit too harsh to create a good image. Looks much better in Infrared.

Have a great weekend.

The Friday Image 005

I missed sharing my Friday Image over the Christmas and New Year break so here is the first one of the New Year.

I shot this image back in March last year on a trip to San Francisco. I don’t know the name of this building and the only location details I have are that I was in the Financial district (I think) when I shot it. The capture was made using a Panasonic GX1 that had been converted to shoot Infrared.  I know most infrared images tend to involve trees, plants and water but it’s easy to forget you can get some great results in the city.

I also plan to produce one of my fact sheets for this image, describing how it was processed because it makes quite an interesting study (well I think so at least). Because the image was shot on a digital infrared converted camera there really isn’t as much information in the colour channels as you might expect from a standard colour shot. My plan is to produce an enlargement for printing at A2 so it will take some careful processing to achieve this given the nature of the image file. I will put a note on the blog once the fact sheet is available.

Have a great weekend everyone.

GX1 V's EM5 V's RX10
GX1 V’s EM5 V’s RX10

So, I have done it. I returned the 14-140 lens for a refund and the money has gone against a Sony RX10. My first impressions are that this is quite a large camera. Actually, it’s not a camera at all but a huge lens with a sensor stuck on the back.

You might feel that I am being unkind but this is exactly what I expected and even wanted. It reminds me so much of the beloved R1 that I sold a few years back. This camera oozes quality and the dials and buttons are a joy to use.

In terms of size, it’s larger that my GX1 (which is now Infrared only) and it’s even slightly larger than the EM5 (which I absolutely love). It’s not however as large as either of these cameras plus the three lenses I would need to cover the same focal length as the 24-200mm lens. The lens also seems to produce great image quality across the entire focal and aperture range. It’s early days yet though.

Annoying limitations at the moment are that I don’t yet have a 62mm filter ring so I can’t really shoot good landscapes. Lightroom also doesn’t support the RAW files so I am having to use the dreadful Sony RAW converter (at least until Adobe release an update). I hated this software when I had an NEX5 and I still hate it now.

I’m looking forward to really getting out with the camera. It’s nice that it’s a sealed unit so less chance of dust getting in there. I also don’t need to stop to change lens so I am thinking this is a great hiking camera for the hill and it should make for a great travel outfit also.

I will report back on the image quality when I have been able to put it through its paces properly.

Big Print from a Little Camera

Posted on Updated on


Print mounted in my front room
Print hung in my front room. I won’t tell you about the fun I had trying to hang this. The house is 200 years old and the walls are somewhat uneven and the plaster prone to crumbling when drilled.

Here’s something that I have wanted to do for a long time, produce a large print from a Micro 43 camera. When I say large, this one is 62″ x 25″. As you can see from the picture here, the print is just a few inches short of the length of the Sofa (which is a 3 seater).

The image was shot in Death Valley and is actually 4 images stitched (with a 50% overlap). The images were shot using a Panasonic GX1 which was tripod mounted and the stitching was done in Hugin. In case you are not aware of Hugin, it’s a freeware stitching application (that’s the simplest way to describe it) which I absolutely love. Here is the resulting image which I have previously shared on this blog.

One of the images I found time to prepare for my recent presentation. 4 images shot on a GX1 and stitched in Hugin.

And in case you are interested, here is a section from the bottom right which is shown at 100%. This section has been taken after the image was resized to create the print above. This is approximately a 200% increase in the print size and was achieved using Akvis Magnifier.

I had the image produced by White Wall and I am very impressed with the quality and service. It’s actually a Lambda print on Fuji Crystal Archive DPII. The print has then been bonded onto Aluminium Matt Acrylic glass and the whole thing has been framed. I have to say, I am impressed and can certainly recommend White Wall from my experience.

There are however a few things to watch out for when producing a print of this size as its quite an investment:

  1. Ensure that you download the colour profile for the paper/print process you are going to use. You should then soft proof your image and check for out of gamut colours. When I did this I found that some of my orange highlights were out of gamut and if I hadn’t corrected this the image would have appeared flat.
  2. Sharpen your image at the final size before you upload it. The White Wall ordering workflow allows you to upload your JPG or TIFF image. It’s then possible to select a larger image and have the system scale this for you. I preferred to scale my image first so that I could sharpen this for the final output.
  3. If you follow my approach and scale your image before upload, I suggest printing a number of sections from the finished image (at 100% resolution). This enables you to judge the quality of the finished image before committing to the transaction.
  4. Now that I have the print I have checked the sample print I made and can directly compare the sharpness and detail. The White Wall print is very good and compares favourably with the image sections I printed on an Epson 3880. The Epson is however slightly sharper. If I were repeating the exercise I would add a little more sharpening. At the time I used Nik Sharpener Pro which allows you to set variables such as viewing distance and resolution. I used a viewing distance of up to 2 feet and a resolution of 2880 x 1440. Looking at the results I should probably have set the viewing distance to “6 to 10 feet” or perhaps even used the Continuous Tone option at 300dpi. It might even be an idea to contact White Wall and ask for a little more information on the Lambda printer as well as recommended Output Sharpening levels.

The only regret that I have is that I picked the Matt Acrylic Glass. One of the things that prompted me to do this was a visit to the gallery of Rodney Lough Jnr. when I was in San Francisco. The images in the gallery appeared to use a similar process (although it was suggested they did this in house and it was unique – I doubt that).

My reason for choosing matt acrylic was to avoid reflections but it doesn’t really. I really wish I had gone for the gloss and tried to counter the reflection with some good lighting – something I still need to invest in for this print.

I suspect I will try another print but this time on gloss and not quite so large.
