I have some good news for all you Lightroom users who own a Panasonic GM1. You can now download for free my custom camera profile at my Lenscraft website. This profile works with Lightroom and can be used instead of the “Adobe Standard” profile.

Once installed you can select the profile in the Develop Module under the Calibration section.

In order to access the profile you will need to be working on a RAW file shot with a Panasonic GM1. If you are editing a TIFF or JPEG file you will see “Embedded Profile” in the Calibration section. If you are editing a RAW file and can’t see the profile you have either:

  1. Installed it to the incorrect location
  2. You need to restart Lightroom (following the installation)
  3. You are working on a RAW file that isn’t from a GM1

Have fun.

Sony RX10 Colour Profile for Lightroom

I have finally managed to find a little time to produce and upload a new Colour Profile for the Sony RX10. The profile can be used with Lightroom and gives a nice improvement over the standard Adobe profiles that come with Lightroom. The improvement isn’t quite as marked as some of the other cameras I have profiled but it’s still better. Blues have more punch and the reds are more natural.

You can find the free download on my Lenscraft website.

I hope you like it.

Printing, Always an Interesting Exercise

Not taken with Lightweight gear but this is the colour image I was using to test my prints. It's quite challenging to print and shows up poor colours quite well.
Not taken with Lightweight gear but this is the colour image I was using to test my prints. It’s quite challenging to print and shows up poor colours quite well.

As I mentioned in one of my previous blog posts, I recently sold my printer, a Canon Pixma 9500MKII. The main driver for this was that I wanted to make larger prints, typically A2 or 17” wide panoramic. I also wanted larger ink cartridges because I do quite a lot of printing and I thought this might help reduce the overall cost. Well, my new printer arrived at the weekend, an Epson Pro3880 which is A2 and will print 17” panoramic up to 37” or wider if you use a third party RIP rather than the Epson print driver. Sounds great and it is, but there have been a few surprises.

First was a nice surprise in how small the printer was. It’s not much wider than the Canon (but it’s a little taller) and fits neatly at the side of my desk. I am also surprised about how little ink has been used in the 30 plus test prints I have made; this barely registers on the ink monitor. I had read reviews and comments by others about just how much ink is in these high capacity ink cartridges but I hadn’t really appreciated it until now. I’m sure however I will be crying when it comes to the cost of replacing just a single cartridge.

Now for a surprise I wasn’t prepared for; the Canon Pixma 9500MKII made nicer black and white prints (I didn’t check colour but suspect it was more vibrant). Before the Canon was sold, I made quite a few test prints on different papers (using high quality fine art and fibre based papers) in an attempt to pick a paper to standardise on. After this I started to use a Permajet paper called Fine Art Pearl 290. It wasn’t quite as good as Ilford Gold Fibre but the differences were so minor that most people wouldn’t spot them but it was excellent for both mono and colour work. As I still had a number of test packs available as well as paper I had purchased I decided to repeat the exercise and the results were very surprising:

As already mentioned, none of the papers could compete with the prints made on the Canon. This was despite producing custom profiles. Held side by side with the Canon the Epson prints looked a little flat where the Canon produced prints with a greater feel of depth.

All the papers tested with the Epson produced broadly similar results when printing in black and white. The main difference was the base colour of the paper. Some were warm tone whilst others were neutral and others still were bright white. The Ilford Gold was however better than the rest and was only marginally beaten by the Ilford Gold Mono.

Printing in colour revealed quite a variation between papers. The Ilford Gold again produced the best results with the other papers looking rather lifeless and flat. Only the Gold had a real depth to it.

This exercise was also repeated by another friend who has the same printer and his results are very similar. In a “blind” review of each other’s results (so we couldn’t be swayed by knowing the paper manufacturer), we came up with identical conclusions. We had to conclude that with the Epson the Ilford Gold was the best paper. This is a real shame because it’s a very expensive paper and the cost will tend to curtail the amount of printing I do.

The story doesn’t end there however because I decided to try out some Fotospeed PF Gloss 270. This is a standard gloss photographic inkjet paper that is around quarter of the price of the Ilford Gold and I didn’t expect it to be very good. Whilst I am not a fan of the Gloss surface I had to admit the results were almost as good as the Ilford Gold for Mono and marginally better for colour prints. This is quite a shock but makes printing much more affordable. I am now keen to try out the Satin or Lustre finishes to see if they are preferable to the gloss surface. If they are I think I will be buying this for my regular printing and saving the Fine Art Papers (Ilford Gold) for any print sales.

The downside to using standard photo papers for printing. They don’t feel as nice as the fine art papers to touch – not an issue when they are framed. They also don’t have quite as nice a surface finish – again this is hard to see if the work is framed and is probably my personal preference.

I hope this helps anyone out there struggling with cost and the difficult decision of which paper to print with.

The Black art of Colour Management

In my last post I discussed some of the choices we photographers now have in choosing paper surfaces for printing. Someone raised a question that I responded to about how to get the colours accurate but I think this subject deserves a more in depth answer; so here is a little more on the subject.

The secret to getting prints to look the way you want them to is all wrapped up in Colour Management. This can be a very simple process but it can quickly become a wide discussion with lots to confuse. I will try to keep this simple and discuss two areas of colour management that are essential to achieving accurate colour (and for that matter black and white) prints. These are:

  1. Screen calibration
  2. Printer calibration

It’s necessary to have an accurately calibrated screen so that you have confidence the colour you see on screen is the colour of the image. This is really vital because you could make your image look great on screen only to find you have compensated for all kinds of colour shifts and contrast problems with your monitor.

There are software solutions that allow you to calibrate your screen visually but these will never be as accurate as a hardware solution that measures the colours on screen, creating a specific profile for your monitor. There are a number of solutions available that will quickly allow you to generate a bespoke profile for your monitor and I suggest you invest in one of these. Its money well spent. Which model you invest in will depend on your budget and the approach you intend to adopt for printing.

When printing, it’s necessary to have your printer calibrated to the specific ink and paper. This allows you to ensure colours and tones are accurately reproduced for a given paper. There are three options here:

  1. Download and install the ICC colour profile for your printer and the paper you will be using. This is good but not as good as having a custom profile created for your printer.
  2. Have a custom profile created using a profiling service. This involves printing out a target image which is then measured to generate a profile. You can then install and use the profile for printing. There are a number of such services advertised in the back of photography magazines. Alternatively if you purchase Permajet or Fotospeed papers, they offer this service for free.
  3. Invest in a hardware solution that allows you to generate your own profile. This is good if you have a lot of profiles you want to create or switch papers often. This is the option I have chosen and have purchased a ColorMunki Photo tool. This allows me to calibrate both my screen and printer. So far the results have been exceptional.

Even if you intend to send your prints away to a printer, it’s still necessary to calibrate your monitor.

When it comes to printing, the printer and paper combination you have selected may not be able to represent accurately the range of colours and tones you see in your image. To compensate for this the printer will adjust the colours so that they fit within the Gamut that the printer can handle. This can affect how some colours appear as well as the contrast level in the image.

The solution to this problem is to use soft proofing for your images. Photoshop, Lightroom 4 and other packages will support soft proofing. This involves selecting the profile you are going to use to print your image and then the software tries to represent the image on the screen as it will ultimately appear on paper. There are lots of solutions here so your best option is to look up how to perform soft proofing for your chosen package. I would even recommend you soft proof your image when sending them off to a third party printer.

So, in summary:

  1. Profile your monitor and set it to use the customer ICC profile (most calibration units do this step automatically for you).
  2. Print using a profile generated specifically for your printer and paper combination. You should then use this profile when printing so you will need to print from an ICC aware application such as Photoshop or Lightroom. I use a package called QImage for reasons I won’t go into here other than to say it makes the job easy.
  3. Check your image using soft proofing before you printing to see if you want to make any further adjustments before you print.

Follow these steps and you will end up with accurate colours and tones in your prints.

Lightroom Profile for Sony RX100

RX100 in Wales
RX100 in Wales

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.

Lightroom Lens Correction for Micro 4/3

Posted on Updated on


The Lens Correction module in Lightroom can automatically correct common distortion problems. These are typically evident in wide angle architecture shots such as this one of New York Grand Central Terminal shot with a Panasonic Lumix LX5.

This is just going to be a short blog today but I’m sure it’s going to answer a question quite a few Lightroom users have. If you shoot in RAW format then you will be using a RAW converter to convert your images to a picture format such as TIFF or JPG. This is one of the common uses for Lightroom which has the excellent “Develop” module (see my Lenscraft website for free membership and tutorials). One of the features of this module is that you can load in lens calibrations for your camera which will apply an adjustment to correct any lens distortion.

It is possible to create your own lens profiles using a lens calibration chart and some free software that can be downloaded from the Adobe website but this is quite tricky and time consuming. Adobe has therefore taken the approach of shipping Lightroom with some standard Camera and Lens profiles that can be selected. These generally correct the major distortions such as Barrelling and Pin cushioning. There are then further manual adjustments you can make to tweak your image. If however you are a Panasonic or Olympus Micro 4/3 user you might have wondered why these cameras are missing from the lens calibration menu.

The answer is simple, Adobe has built the profile correction into the software and it is automatically applied without needing to select the camera and lens. When I first read this I was a little sceptical but I managed to hunt down the confirmation on the Adobe web site with the answer coming from one of their senior engineers.

So all you Micro 4/3 Lightroom users out there, if you are still not happy all the lens distortion has been removed, turn to the manual adjustment sliders. If of course you have a compatible lens calibration chart, the software from Adobe and a lot of time and patience you could always create your own.

Color Passport Update

Posted on

In past blogs I have discussed how useful I find the Color Passport from Xrite. Initially I used this to set my white balance in the GX1 so that the AWB setting I tend to use almost 100% of the time is more accurate. Previously this was setting the colour temperature to 4,700K and the tint adjustment in Lightroom to 0. Having created a custom white balance the colour temperature has increased to 5,400K and the tint to +8. These are significant corrections and ones that I probably wouldn’t have landed on myself.

The other thing I have used the Color Passport for is to create a custom calibration profile for the GX1. Again this is having a dramatic effect as the contrast increases, pinks have become more vibrant, orange less saturated and blues and greens look more natural. I now use this profile as the starting point for all my conversions for the GX1.

The other night I was adjusting images before sending them to my stock library. My workflow for this uses a separate package for keywording and Lightroom for the RAW file conversion. What I happened to notice when doing this was that the thumbnails in the keywording application appeared more natural than the image in Lightroom, despite having used my custom camera calibration. After a little adjustment to the calibration slider I found setting the Green Hue to -33 and the Green saturation to -11 gave me much more natural Landscape greens.

Now I don’t know if this setting will work for all images so I decided to apply it to other shots in the batch. I created a custom Lightroom Preset and applied it to a few others. Yes they improved but there was also an interesting side effect with some. Applying the preset seemed to change the histogram substantially. Histograms that lacked contrast and that were gathered in the mid tones now extended across a greater tonal range and in some instances filled the histogram. Looking more closely at these images I found the details appeared crisper (which might be expected from improved contrast) but the luminance noise appeared reduced even though I hadn’t applied any noise reduction. Whilst you might struggle to see what I am talking about at this reduced resolution, here is a comparison from the above image (click the image to enlarge).

I will keep a close eye on this in the future, but it seems to have given a promising improvement to quality, which is all important with stock images.

Color Checker Passport

Posted on


Image

A little while back I mentioned that I was unhappy with some of the colours being produced by my GX1 and also LX5. The greens seemed a little too green and the image overall had a slightly blue cast to it. This inspired me to purchase a Color Checker Passport from X-rite as it could be used to produce a custom calibration for your camera which can then be used in the develop module of Lightroom. Well I have now purchased and used the passport and can report on its performance.

My first reaction when opening the packaging is that you don’t get a lot for your money. The passport itself is small and made from plastic. There is a CD containing the software which you load to your computer but there were no instructions other than a link to the X-rite site. In the end I watched a very good video of how to use the passport and software to generate a profile and all was clear.

The passport is basically a colour checking chart and grey card contained in a plastic cover. It’s small, light and fits neatly in your pocket. The first thing I used was the grey card in order to create a custom white balance for my GX1 (I won’t describe how to do this here as each camera is different). This was very simple and once the white balance setting was registered made an instant improvement to the images, removing the blue colour cast preventing the greens from looking quite so sickly.

Next I took two reference pictures of the colour chart in the passport. One was in direct sunlight and the other in shade, both taken around midday under a sunny sky. Back at home I converted the RAW files for the two images into DNG format using Lightroom and then loaded these to the passport software. A click of a button and 20 seconds later and my profile was ready.

Restarting Lightroom and switching to the Develop module I could see my new conversion profile which when selected had an immediate impact on the image. I noticed that the image contrast improved and some colours (red in particular) became much more vibrant and realistic. Colours also looked completely natural.

I wondered if this result had been a fluke so repeated the process with my LX5. The results were even better and the images now look very lifelike. The image here is of the edelweiss flower (I hope I spelled that correctly) which is actually quite rare and grows at altitude in the Alps. I found this particular flower at around 2,600m under a bright blue sky and took the picture on my LX5. The colours having used the “passport color checker” appear completely natural and subtle.

This tool is quickly becoming an indispensible accessory in my camera bag. I just need to remember to use it.
