As regular readers will be aware, I have recently been sharing my thoughts about the Canon G7X camera recently. My previous posting on the subject was a little critical as I had found that on very long exposures, light appeared to be leaking into the camera through the lens barrel. I would now like to balance this with a brief post demonstrating the image quality that’s now possible with even compact cameras.

The image above is a long exposure of Burton Falls in West Yorkshire. To avoid the problem with the light leaking into the camera I wrapped a cloth around the lens barrel. On processing the image in Lightroom the image quality is evident. Below you can see a close up of the image at 100% magnification prior to processing.

Depending on your screen resolution you may need to click on the image to review it properly.

What I found interesting is how clean the image was when I then went to touch it up in Alien Skin Exposure 7. I started with a Fuji Provia slide film simulation but turned off the grain. I then adjusted the sharpness and clarity very slightly. Below you can see the same sections from the image after processing.

If you would like to see a full resolution JPG of the image you can find it here (I had to drop the JPEG quality to 10 due to the file size).

You don’t need to look back too many years to find this beats the pants of many DSLR’s.

The Power of a Letter

Posted on

This story has nothing much to do with Photography but I wanted to share it as it restores my faith in people.

Over the weekend I was in France to visit my daughter and her partner for my Grandson’s first birthday. Whilst my daughter and her partner don’t have very much money they wanted to give my grandson Zach a wonderful first birthday. They collected together the various gifts of money before taking him to the toy shop. They had seen a lovely toy car (similar to the one shown below) that Zach could sit on to push himself around. As soon as he saw the car in the shop his face lit up with excitement and he started to point to the car that he liked. We had one little excited boy on our hands and my daughter bought the car.


With the car purchased and gift wrapped by the shop, my daughter headed home and I went back to the hotel with my wife. Later we went to their flat in the hope of seeing Zach with his new car. Unfortunately this wasn’t to be. You see a friend had seen my daughter struggling home with shopping and stopped to give a lift. When they arrived home they unloaded the shopping and started to carry it into their flat. Struggling with a bulky pram, a child and shopping, they couldn’t carry everything at once so left some things outside. It was at this point that my grandson’s first birthday present went missing.

After a lot of hunting around they placed a notice on the entrance door to the flats in the hope that the person who took the present would see and return it. The letter was from Zach and simply read that he had lost his first birthday present and if someone had taken this for safe keeping could the let his daddy know as he wanted to play with it.

This morning the letter has gone. In its place was an anonymous reply wishing him a happy birthday and enclosing 50 Euros. It went on to say that if he didn’t find his car they hoped this would help him to replace it

The generosity of people never fails to amaze me.

New Brush in Lightroom 6

I recently published a Friday Image and mentioned that I had found a new brush tool in the Lightroom filters. My intention was to post a blog explaining a little bit more but the lack of time has prevented me from doing so. That is until now.

The new brush is available with any of the Filter tools (Graduated or Radial) and can be seen on the following screenshot.

It becomes available the moment you draw a graduated or radial filter on your image or select one that already exists. Click on the Brush heading and the brush settings appear at the bottom of the filter panel.

You might well recognise these settings as they are identical to the Adjustment Brush tool. You have two regular painting brushes and an Erase brush. The regular brushes allow you to expand the filter effects to other areas of the image whilst the Erase brush allows you to remove the filter effect from an area.

As a Landscape Photographer, the best use I have found for these so far is where I am using the Graduated filter to darken a sky but there are elements above the horizon which are also adjusted. Previously I would need to drop out of the Gradient filter and use the Adjustment Brush to lighten these areas. Now I can use the Erase brush to stop the effect from being applied in the first place.

One other tip for using the brush tool with the Gradient or Radial filter is to ensure you check the “Show Selected Mask Overlay” option at the bottom of the screen.

This displays a red mask which allows you to see the changes you make to the mask as you use the brushes.

If anyone comes up with other useful ways to use this feature I would be interested to hear.

Canon G7X Field Report

Yesterday I met up with a friend for some well-deserved landscape photography. We had intended to visit Anglesey but the weather forecast was dreadful and so decided to visit Yorkshire instead. It was also a useful test of my new G7X to see how it faired in the field, especially as the Lensmate filter adapter had arrived from the US.

The Lensmate adapter was very easy to fit and whilst it’s made of plastic and feels a little flimsy, it just works well. I was able to screw in my Lee Seven 5 filter rings and use the same filter system as I use with my Micro 43 kit. The profile of the Lensmate is very thin which allows the camera to still fit in a pocket.

As the weather wasn’t really great for photography (damp and overcast) I spent most of my time shooting long exposures. For this I was using the Lee Little Stopper 6 stop Neutral Density filter. The image at the top of this post was shot using the filter attached to the EM5. Using it with the G7X I noticed a few things some of which I’m not too happy about.

The first thing was that no long exposure noise reduction. I went all thought the menus and settings but I couldn’t any settings and neither was it being performed automatically. Having said this, the results don’t appear to be suffering from long exposure noise.

The second thing I noticed was that when in aperture priority mode the longest shutter speed is just 1”. No problem really as I could switch to Manual Mode which allowed much longer shutter speeds, but it is a basic omission.

The third thing I noticed is that the display on the back of the camera could see through the 6 stop ND filter very clearly and which made composition much easier than with the EM5. The EM5 seems to struggle a little with these very dark filter.

The fourth thing that I noticed and which is something that I’m not happy about is that light is leaking into the camera from the lens barrel. Take a look at the following filter.

This is light leaking in where the two parts of the lens barrel join which allows the lens to extend and retract. The red in the image is the reflection from my red jacket which is reflecting off the back of the filter attached from the camera. I found that I was able to block it if I wrapped the lens barrel in a cloth. The other alternative was if I zoomed in as the problem was only really evident at wider focal lengths. I will be contacting Canon to see what they have to say about the problem.

Despite this problem, the camera seemed to perform well and the image quality was good. I will be posting something further about this soon.

Olympus EM5. Irregular blurring in Lightroom 6 using a Radial Filter

At the moment I have a really strong feeling that I want to shoot some coastal scenes. I haven’t been getting out very much at all with my camera as there have been too many other things that I need to do that unfortunately don’t relate to photography. The best I can do is content myself with looking back over past images and choosing some to reprocess.

I then started to process the image above in Lightroom which is where I came across a rather interesting feature that I think is new in Lightroom v6. At least I don’t recall it in an earlier version. When using tools such as the Gradient Filter or Radial Filter a mask is automatically created. There is now a collection of brushes within these tools that allow you to refine the masks. Experimenting with a Radial Filter I was able to make the selective adjustments to blur irregular areas of the image. I’m going to investigate this further and will probably pull together a short piece about it.

Have a great weekend everyone.

My First Impression of the Canon G7X

Posted on

Zabriskie Point, Death Valley

In my previous post I mentioned that I was going to buy a Canon G7X given how impressed I was with the G16 compact camera I had been using. Well it arrived yesterday and I have decided to do something unusual. I’m going to give a quick review of my first impressions having not yet taken a picture with the camera (I haven’t even put the battery in the camera).

I bought the camera because I thought it was the same body, or at least very similar to the G16 but this isn’t the case. I was quite surprised to find the G7X feels a fair bit smaller than the G16. The G16 has a rubber hand grip on the right which feels quite chunky and nice. The G7X by contrast feels thin, small and a little slippery. The handling reminds me of the tiny Sony RX100 I had (hence the image above).

The tilting screen on the back of the camera is nice but why has Canon not gone for a fully articulated screen. The screen is limited to tilting upwards with the hinge along the top. This is fine if you have the camera in Landscape mode but if you want to shoot with a portrait orientation it doesn’t work. Despite this, it’s an improvement on the G16 which doesn’t have any screen tilting.

The next thing I noticed is that the controls are very small and cramped, much of the space having been given over to the screen. This makes them a little tricky to use if you have anything other than small hands. The use of the dials on the top of the camera has also been changed, again making them a little tricky to use. I can foresee a problem when using this camera for Landscape Photography in cold weather.

Despite the limitations of the size of the buttons and dials the layout of these is very well thought out which does make them very usable. This also makes the G7X a true pocket compact. The G16 may feel nicer in the hands but you need a big pocket to carry it around.

The camera came with a strap, but this was only a wrist strap which may trouble some people. My automatic reaction was to want a neck strap but then I have a habit of wrapping this around my wrist a number of times to carry cameras in my hand. Perhaps the wrist strap with this camera will be helpful and again make it easier to fit in a pocket.

The final point I notice is that there is no way to attach filters to the camera. On the G16 there is a removable ring around the lens which then accepts an accessory tube to which filters can be attached. With the G7X the ring doesn’t detach but instead has a number of functions that can be assigned to it. As filters are essential to my work I have ordered a stick on adapter from the US. This again is similar to what I had to do with the Sony RX100.

One minor lucky point is that the screen protectors from my EM5 fit the G7X screen so I don’t need to buy any of these and can put the money towards some spare batteries. The battery for this camera is tiny and I can’t imagine it will last all that long, although we shall see.

In summary the G7X is a very well designed and well-built camera but it feels as though Canon have tried to copy Sony (even down to the 1”, 20Mpixel sensor) and in the process thrown out some of the better points from their G range.

I will share further thoughts as I begin to use the camera.

I Love the Canon G16

I have been using the G16 pocket Camera quite a lot recently and the more I use it the more I like it. I find the build good and the image quality very good. It’s easy to use and whilst it doesn’t shine in any one area it’s a great, well balanced package that’s a joy to use.

In fact, I like this camera so much I am going to sell it.

The reason is that I have been enjoying using it so much that I couldn’t resist buying a Canon G7X. The G7X is pretty much the same body except that it has an articulated screen which is something I really wanted on the G16. The other major difference is that the G7X has a 1” sensor and is 20Mpixels.

When I saw the discounted price on Amazon (reduced to £350) I couldn’t resist. I do hope it handles as well as the G16.
