After I published the Friday Image No 20 I decided to review my Olympus EM5 shots. I had taken a few of the same location with the extremely sharp Olympus 45mm prime. You can see one particular example above.
What I noticed, that took me completely by surprise, is that I can see traces of noise in the EM5 image which isn’t present in the GM1 shot when viewed at 100% magnification. I have always been impressed by the EM5 images and just how clean the images are, but the GM1 appears to surpass this when both cameras are used at their base ISO.
If you are wondering why I find this so important, it’s because this noise becomes amplified in post processing, especially when enhancing images with structure and dynamic contrast tools. The less noise is present, the higher the quality of the finished image and the less noticeable any image artefacts are.
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.
First, I must apologise for the visual pun and poor quality of my humour. I also must admit to a rather strange fascination with rock and a desire to photograph rock. I can’t put my finger on why but I just love the texture and sometimes the colour of rock. The image above is typical of what I like to shoot, where detail and texture are all important. The ability of my camera and lens combination to capture this detail is therefore very important to me. In this example it was a Panasonic GX1 and Panasonic 14-45mm lens (this by the way was the old kit lens for the GF1 and is a real cracker in terms of the image quality it can produce).
As some of you reading this will know, I recently made the decision to sell all my DSLR equipment and switch completely into Micro 43 format cameras. This lead to the purchase of an Olympus OM-D E-M5 which I am very impressed with but leaves me with a Panasonic GX1 doing very little. I had been contemplating selling the GX1 body given that it is pretty similar to the OMD. It produces the same size images and has nothing about it that elevates it beyond the OMD. I can’t however bring myself to sell it.
The GX1 has now come down to such a low price that I don’t feel it’s worth my effort to sell it and that I may be better keeping it. The body is pretty tiny and fits neatly in my pocket or camera bag as a backup. The build quality is very good. And when I look at images such as the one above it amazes me what quality the camera can produce (when shooting in RAW format). Take a look at this section viewed at 100%.
So for now at least, I think it’s going to stay in my camera bag – it makes an ideal travel camera.
So, that was the blog I had originally intended to post. The only thing is, the image wasn’t shot on a GX1 at all. It was shot on my Sony RX100 but I had copied it to the wrong location. That’s right, it was captured on a compact camera. WOW!
I wanted to end this blog with a question. Which image is better, the colour one above or the black and white conversion below? I can’t make my mind up but I’m interested to know what others think. I think I prefer the colour image but it’s a close run thing.
I have written in the past about two things that I would like to give an update on. The first is the software I use to perform Infrared RAW file conversion. The other is my impressions of Photo Ninja. As you will see in a moment the two are now linked.
When I first ha my Panasonic GX1 camera converted to shoot Infrared I had thought that I would be able to shoot images in RAW format and process them in Lightroom or Photoshop. I had read that there was a problem in doing this with Canon and Nikon RAW files as Adobe software rendered the image as shades of red with no other colour present. This prevents you from converting the image using “false colour” (do a search on Google for colour Infrared to see some examples). It also seemed to limit the quality of the image conversions as most of the image data was coming from just the red channel.
I wasn’t however worried by this problem as no one was reporting an issue with Panasonic conversions from Infrared RAW files. Unfortunately I can confirm it is a problem and also conclude that there can’t be many people using infrared converted Panasonic M43 cameras. If you want to know what I am talking about, here is an example of the above image in Lightroom 4.
My initial solution to this issue was to use the SilkyPix software that ships with Panasonic cameras that shoot RAW. This gave good results in managing image colour and allowed me to set a true white point so that images didn’t appear red. Once I had upgraded this (I took advantage of a very cheap special offer) the image quality was OK if not a little too smooth for my liking.
More recently I had some very promising infrared images but felt that none of my RAW converters were doing justice to the levels of detail present. I decided to try out the PhotoNinja software again and the results have convinced me to purchase the full version of the software. Yes it’s expensive but the results are visibly better. This is not just with Infrared images but colour also. Take a look at the comparisons below.
These are conversions from Lightroom, Silky Pix and PhotoNinja, all taken from the same RAW file. I should caveat this a little in that I know exactly what I am doing with Lightroom but am pretty much a novice in using SilkyPix and PhotoNinja. It’s therefore likely that better results can be achieved with both of these. It’s the same story in colour also with the PhotoNinja conversions producing more detail, especially if you sharpen them further post conversion.
Wondering why there is no SilkyPix comparison? Well it kept crashing when trying to open the files. I suspect there is a compatibility problem with Windows 8 but I need to do a little more digging. You might also notice the much better colour rendering from the PhotoNinja software which is far closer to the scene as this image was shot about 20 minutes before sunset in direct light.
So, if you are looking for a RAW converter to give the highest level of quality (and don’t mind the price) I would certainly take a look at PhotoNinja.
I won’t bore you with the details but all of my free time (including that I use for blogging) has vanished, at least for the short term. I am actually putting this blog together whilst trying to eat some lunch. Yesterday however I was fortunate to have a day out on a photography course designed to allow you to try out a camera – the Olympus OMD.
This Olympus Experience Day was put together by Olympus with pro landscape photographer Steve Gosling. I like Steve’s work a lot and having been on his “Business of Photography” course some years back so very interested in attending this day. The course was held at the RHS gardens in Harrogate and whilst not my usual subject matter I found a few things to shoot and try out the camera. What I thought was good (other than the exceptional value of the day) was that I had an OMD to myself for the entire day.
At the start of the day there was a short session to help delegates understand how to use the camera followed by a questions wrap up at the end. In between Steve spent time with each person individually to answer any questions they may have. I think this is a great way to allow people to try before you buy and I wish more manufacturers would follow the model (other than Hasselblad and Phase One as I can’t afford their hardware). It was also a great day with an experienced pro photographer and opportunity to draw on his experience and thinking.
Now you know I was impressed by the day, what about the camera.
I really like this camera, but to be honest I didn’t expect to at the start of the day. I had read some horror stories about the poor menu system which is something I have experienced before with my NEX5. I actually found the OMD’s menus quite logical and was able to set up the camera relatively quickly. It was certainly much better in my opinion than the NEX5 (when first launched).
I tried the camera with the 12-50 Olympus lens, my 14-45 Panasonic lens and my 45mm Olympus lens. It handled extremely well with all and felt very solid in the hands. I wasn’t however that impressed with the 12-50 lens other than a very nice macro function it offered.
To me, the most important aspect of a camera is how it handles and the image quality produced. I have to say, this is an exceptionally well made camera which feels very durable. The image quality is also very impressive for a Micro 43. Much of the day I was shooting at ISO400 or ISO800, something I would avoid with my GX1. The image above was captured inside a potting shed at ISO800 and my 45mm lens hand held. It’s very sharp with no camera shake and is very clean in terms of noise. In fact I can’t believe how clean the images from this camera are. I will have no issues submitting ISO800 images to stock libraries and believe me; I am very picky about this.
So will I buy one of these cameras? I would certainly like to. The only thing stopping me is that I have just sold my Canon 9500 printer with a view to upgrading to A2, so that’s my current priority. I may therefore need to stick with my trusty GX1’s for a while longer.
It’s been a very busy month and its set to get more hectic for me. I have quite a lot on in the run up to Easter so I am going to take a short break from the blogging for a couple of weeks. Rest assured I will be back soon with new material and lots of opinions about Light Weight Photography.
So you don’t forget me I thought I would leave you with a nice image of an interesting tree shot in Infrared.
After my previous post, I am no longer feeling sorry for myself and am well on the road to recovery. In fact I am feeling quite satisfied as I have finally completed my book “The Panasonic LX5: How to Achieve Exceptional Image Quality” which has been on the go since November last year.
As the title suggests then book is about how to create exceptional image quality with the LX5. It is supported by a worked example turning a standard LX5 image into a highly detailed 30” print. If you are a member of my Lenscraft web site you can download the full resolution 30” image for a closer look. The only rule is that you can’t sell it, change it or pass it off as your own work.
If you want to find out more about the book you can find the details here.
Hopefully normal blogging resumes from next week.
I have been trying to create a new camera profile for my Sony RX100 in Lightroom for a few weeks but had been unable to get the software for my Passport Color Checker to work properly. I have now traced the problem to the new version of DNG files that Lightroom 4.3 creates (Lightroom 4.2 seemed to work fine). I resolved the problem by saving my DNG files in the old DNG version 6.6 format.
Don’t worry if the above doesn’t mean much to you, if you have a Sony RX100 and use Lightroom you might want to download and try the profile I created. I found the profile improves the reds and blues (particularly) over the standard Adobe profile.
You can download my profile for free from the Members Area of my Lenscraft. You will need to have signed up as a member but that gives you free access to everything on the site and I don’t pester people with emails other than a quarterly newsletter and the odd announcement.
If you use Lightroom and have an LX5 or GX1 you will also find my profiles for these cameras in the same location.
I hope you find this useful.
I have just answered a question posted on yesterdays blog and it made me realise I am missing the obvious again. This time it was that most people reading my blog have probably never seen a direct conversion from a RAW infrared file. Neither will you probably know what all this problem is with white balance and why I was so concerned. Here then are some examples that hopefully will put this right. All are created from the same RAW file used for the image at the top of the page and I have done no other adjustments to the files beyond what I explain below.
This first example is what you get in Lightroom when you set the camera white balance to AWB and all the other sliders are at 0.
The next example shows what you get in Lightroom when you set the camera white balance correctly for infrared light. Better but still not correct.
Here is the same RAW file in SilkyPix using the correct Infrared white balance. Notice the difference in colour from the Lightroom image. In this image there is much more information in all three colour channels and it makes for a better conversion to black and white.
The next example shows what happens in SilkyPix when you set the white balance using the white balance picker on the grass near to the castle. This is how the file should look before converting to black and white. This gives a nice spread of information in all the channels and makes for a high quality conversion. Even though a lot of the information in the B and G channels is probably interpolated by the RAW converter, it still appears to be a better conversion and that’s what I am interested in.
In this final example, I have done a channel swap between the Red and Blue channels to create a false colour. Not to everyone’s taste but it can be quite effective.
I am always on the hunt for new ways to do things that can improve my photography. You only need to achieve a few small quality improvements and it can quickly add up to dramatic improvements in your work. One area that I had been exploring was RAW converters and some of you might have seen an earlier post I made about Photo Ninja which looked very promising but was quite expensive. My decision was therefore to stick with Lightroom which performs well.
More recently with my new found passion for Infrared photography, I have identified that Lightroom isn’t good for processing RAW files from my converted GX1. The quick explanation of this is that Lightroom can’t set a white point for the infrared image and you end up with an image which is red. This then prevents you from using a technique called channel swapping to produce false colour but it also appears to detract from the quality of the final image when working in black and white. My search was on then for a RAW converter to use with my infrared images.
I returned initially to Photo Ninja which did a good job and allowed me to set a correct white balance. Unfortunately the cost put me off although I did come close to making a purchase and probably would have if it wasn’t for RAW Therapee. This is a free RAW converter which performs well and has some nice features such as allowing me to do a channel swap during the RAW conversion. The only problem is that it’s tricky to use.
I moved on to search for another free RAW converter “Bibble” which it seems has been purchased by Corel and is now sold as Corel Aftershot. This works well enough and is good price. I just had a niggling feeling that I shouldn’t make a purchase just yet.
After a lot of searching and experimentation I remembered that Panasonic Cameras capable of shooting RAW images are packaged with a special version of the SilkyPix RAW converter. This is version 3 of the SilkyPix Developer Studio that has been limited to only working with Panasonic cameras. Whilst it won’t convert my Canon and Sony files it will process my GX1 and LX5 images fine.
After initial experimentation with the latest version I found the images to be super quality, containing lots of detail, appearing nice and sharp, with good colour and being free from noise. They are in my opinion better than those from Lightroom (both traditional and infrared images). Here is a section of the image above at 100% (click the image to zoom in).
The real decision maker for me is when I received an email the day after offering an upgrade to version 5 developer Studio (still limited to Panasonic cameras) for JPY3800 (about £24). Decision made!
I am now therefore using SilkyPix for my infrared RAW conversions and am extremely pleased with the results.
