Month: August 2016
If you have been following this blog of late you will have no doubt read about my possible switch to the Fuji XT1 and the problems I have encountered. The problems became evident after I shot my first few images and noticed the camera wouldn’t resolve grass very well at all, rendering areas which should contain fine detail as a green mush.
Many of you made some valuable suggestions for which I am very grateful. Apparently this is quite a common problem and relates to the RAW converter not being able to translate the data from the XTrans sensor very well. Some of you agreed there is a problem whilst others haven’t noticed an issue. I have three points to make on this before we start to look at the RAW converters.
- There appears to be variation between cameras judging from some of the RAW files people have shared.
- There is variation between lenses used. I have two lenses, an 18-135 and a 10-24. At the common end of the focal lengths (18-24mm) the 10-24 lens performs much better than the 18-135. I have also noticed that the 18-135 lens is softer and less able to resolve detail across the focal range. That’s no great surprise but it seems to exaggerate the issue.
- If you’re a Mac user, you might be interested to know that you probably don’t notice the issue. But before you get excited, I believe the issue is being masked to some extent by the brilliant retina display. I suspect the pixel density is hiding the effect as I can process an image on the Mac and it looks great at 100% but move the resulting file to my Windows PC and it’s not good.
With these points in mind, let’s take a look at how we will evaluate the available RAW converters.
RAW converters are really quite personal tools. What one photographer likes will drive another crazy. Some will see fault where others will see perfection. What some may see as essential others will see as a waste of time. So here are my categories for evaluation and they are in the order of importance I place on the feature:
- Ability to render fine detail in the converted image.
- Natural colour rendition and the ability to control colours.
- Control over sharpening and noise reduction.
- Support for lens profiles and automatic lens correction.
- Support for colour profiles.
Some functions such as exposure, saturation, contrast, shadow and highlight controls are a given. If the converter doesn’t provide these then it shouldn’t be on the market to my mind.
In the next blog post I will look at how some of the available converters fair in my assessment.
Oh, I almost forgot to mention, the 18-135 lens is going back. I should have known there was a problem with it when some of the early test shots produced images such as the one below. Just because the issue seemed to right itself doesn’t mean it’s entirely fixed.
My previous post detailing problems I have seen when trying to process RAW files from my XT1 has caused quite a bit of feedback. As many of you have pointed out, this is a well-known and documented problem with the Adobe RAW converters. Apparently it’s been largely fixed except that in my opinion it hasn’t.
What I’m going to share with you over a few blog postings are some findings. It appears quite a few people who read this blog are Fuji users so I hope some of you find this useful. To remind you of the effect, take a look at this image and image section.
This image is a RAW file and has been sharpened. The red box on the left shows the area of the crop with the right side of the image showing this area zoomed to 100% magnification. The image itself is sharp but the detail has been lost and now appears to be more like a painting than a photograph.
I’m pleased to say that I can now achieve much better results through the steps I have taken.
There are only two things that I have done that made a difference:
- Upgraded the firmware of the camera and lenses
- Switched RAW Converter
Starting with the firmware (a tip from Dave Shandley – thanks Dave), this was 4.10 for the camera body and has now been upgraded to 4.31. One of the lenses had version 1.10 firmware (the latest) but the other had 1.01 and so was also updated. This seemed to improve the results, not just of the RAW files but also the JPEG images. This had me producing acceptable images, even in Lightroom although I can still detect the water colour effect in the fine details.
The second improvement was to the RAW converter. I will be writing about these findings in a little more detail in a separate blog post as I think everyone could benefit. To give you a flavour, here is a test file I produced together with some close-ups.
File from Lightroom at 100%. This was after the firmware update.
File from Affinity Photo at 100%
File from Iridient at 100%
In my testing, Lightroom really struggles when converting Grass but it also struggles to pull decent levels of detail from the Fuji RAW files. Every RAW converter I tried performed better. I also ran some of the Olympus and Sony files through the other converters and found they were either on a par with Lightroom or better.
In testing the Fuji with Lightroom, I came to realise a few other things that people might find helpful:
Lightroom noise reduction, particularly colour noise reduction hurts the quality of the Fuji files and seemed to add to the effect.
Hard sharpening of the Fuji files in Lightroom seemed to make the watercolour effect more obvious rather than pull detail. I would suggest using the detail slider at the maximum value, the Amount slider below 25 and Radius slider below 25. I would also use the masking slider between 10 and 30. Once you have the file out of Lightroom sharpen it with something else such as Nik Sharpener Pro or Focal Blade.
Shooting at a higher ISO improves the look of the image. I found an ISO setting of 800 seemed to give the image a little more definition. I also found that adding a little grain or noise to the image could help reduce the effect.
I have two lenses for the Fuji, a 10-24 and 18-135. I knew the 18-135 was a compromise but I wanted it for single lens use when out walking. Lightroom definitely made a better job of sharpening and detail extraction from the 10-24 lens, almost to the point where I would question the 18-135. Running the same files through the Iridient RAW converter was amazing. Details that were blurred and out of focus in Lightroom snapped into sharp focus.
I don’t want to say too much more in this blog other than I am very impressed with the Fuji XT1. It’s also a great camera to use.
Over the last few months I have been noticing an increase in the image noise from my EM5. Some areas which you would expect to be free from noise, such as clouds and blue sky, are starting to display faint traces of noise. These then become quite exaggerated when processed hard with Nik filters. In addition, I was beginning to feel that the greens and blues in the EM5 images just weren’t quite right, but it was difficult to put my finger on the problem.
It’s hard to say when this started but it may be that I was becoming increasingly fussy about quality as the Sony A7r was generally producing much cleaner images. A further factor may be that where I had begun to process old RAW files from the Canon 300D I was also seeing a very clean image, surprisingly so. All these factors started to suggest to me that it might be time to upgrade the EM5 or perhaps even switch to another camera manufacturer.
My intention had been to hold out and get the new EM1 when Olympus gets around to launching but I don’t know what the timeline is. In any case, I didn’t feel that happy with the Olympus colour handling and it certainly wasn’t as good as the Sony. These perceived problems together with my impatience lead to me trying a Fuji X-T1. The Fuji line up would also give me a great ultra-wide angle lens in the 10-24mm that would also accept filters. This was a failing of the Micro 43 ultra wides with only the Olympus 9-18mm taking filters but which suffers from edge distortion at 9mm (at least that’s what I was telling myself).
Hopefully this gives you an idea why last week I purchased a used Fuji X-T1 together with 2 lenses. Now the EM5 has taken revenge by making me regret this decision.
At the weekend I collected the new camera from the post office and headed off to the Peak District to try it out (between the heavy showers). Later with the images on my computer, what I saw shocked me. I called my wife in to get her opinion of the images and the first words out of her mouth was that the Fuji image “looked like a watercolour painting”, and that’s without zooming in on the detail. You can see this image below.
When you zoom in to the detail you don’t see much at all other than blur. Take a look at this 100% crop from the point of focus. You may need to click the image below to appreciate it fully.
Now let’s compare this with an image shot on the EM5 from a couple of weeks earlier.
And again, here is a 100% crop from the point of focus.
Both images have been sharpened only slightly in Lightroom as part of the conversion from RAW. I found I couldn’t sharpen the Fuji very much without causing artefacts. Both images have noise reduction turned off. Both sections are from the point of focus.
I can also tell you that this effect has occurred on all the Fuji images using both lenses and across different apertures. Fine details just vanish and become smudged.
I find this unusual as a friend who has the same Fuji shared a RAW file with me before I bought the camera so I could check the image quality and it was much better than I seem to be able to achieve. Another friend has also just shared a link with me which confirms the “watercolour” effect is a known problem with the Fuji XTrans sensor when using Adobe RAW converters.
I will need to investigate this further but if I can’t find an easy solution the camera will need to go back. This would be a shame as it’s a really great camera to use. Perhaps I should have waited for the EM1 MKII after all.
This week I want to share an image from last weekend. A friend offered to meet me at Higger Tor to get a few morning shots. I have never been to Higger Tor before although it’s on an hour’s drive from my house. When I arrived there was only his car and someone camping at the side of the road.
The weather for once was on our side and I thought the location was amazing. I can’t believe that I don’t shoot in the Peak District more often. It seems to be much under rated and we don’t see enough images from the area. I suspect this is because they aren’t quite as dramatic as many other locations.
I hope you like the image and have a great weekend.
Back in the 1990’s I recall reading an article about something called the white goods index. It was intended to measure how much better we are all as a result of white goods becoming cheaper in relation to how much we are all earning.
On Saturday I took delivery of a new freezer. Our old chest freezer had broken a few weeks back and the lid no longer closed. The replacement we bought was duly delivered and filled with all manner of food. Whilst loading the new freezer my wife suggested I buy a second smaller freezer in which to store my photography film. My initial reaction was to think this was an extravagant waste but then I stopped and thought about it. A quick search on the Internet and I found a new freezer for about the same price as three boxes of Kodak Provia in 120 format.
Today I loaded the new freezer with all my film from the fridge, and our new main chest freezer. Seeing all this film in once place made me realise just how much I had. The value is many more times the cost of the freezer and there are a few more benefits. My wife is now happy that she can put food in the freezer box in the fridge. She can store and access food in the chest freezer more easily. I might start using film faster than I have been buying it. Perhaps this last point is pushing things a little too far though.
If you shoot with a small sensor camera and use Lightroom for RAW conversion, then it’s a good idea to take care when sharpening. Noise can be a particular problem when at low ISO settings but there are steps you can take. This video demonstrates how to avoid the ugly sharpening artefacts that can result and which tend to become exaggerated in later processing.
I hope you find this useful.
Last week I was in the Lake District followed by France. That seems so long ago now that I thought I would share one of the images. This one was captured on the Olympus EM5 and is three shots merged in Lightroom. The light on the day was quite blue and the hills were a very vivid green so this image is pretty true to life. I did do a little post processing in Alien Skin Exposure X, applying the Agfachrome 1000 RS slide film simulation. If you think you can see noise in the sky, it’s actually the grain simulation.
Have a great weekend.
