Infrared lens hotspot.

Good morning. 

If you have purchased the infrared filter as i previously mentioned in a blog post couple of weeks ago, and have been shooting with it, you will have noticed the strange colouring that you have received. 

The bright red file is normal, Prior to shooting setting a custom white balance is recommended. A lot of advice i have read is setting it again green grass or foliage. For the below image being a city scape there wasn't much grass around, so i chose to shoot in RAW and play with the white balance later in post. 

One thing i have learn is the visible hot spot in the centre of the image. I shot this using Nikons 24-70mm f2.8 and lens hot spots are a most common problem encountered when shooting infrared light. They usually manifest in the form of a bright circle, sometimes in the shape of aperture leaves directly in the center of the image. The problem is exaggerated as you stop down (increase f stop number), with the spot becoming more prominent and defined. 

Hot spots can be caused for a variety of reasons, the most common of which is the coating on the inside of the lens barrel being reflective in IR light. Another frequent reason is light interaction between the coatings of the lens elements. A less common reason is light interaction between the lens elements and the imaging sensor(usually the micro-lenses) in the camera. In this case using the lens on one camera model may have no hot spot issues and on another model there could be prominent hot spots.

Unfortunately, if your lens has this issue the only solution is to simply use a different lens altogether. Fortunately the majority of lenses don’t have this problem or the problem is very minor and normally not visible in images.

Once i find a suitable lens and am happy with the results ill report back. 

If you have any suggestions to use on a Nikon body id like to hear your views. Feel free to use the contact page.

I hope that you enjoy these images. This is a new technique and something i am enjoying playing with.

Morning, 

Here is a Black and White processed infrared image of London's MoreLondon area, with the town hall and the Shard building. 

My next blog post on Monday i will be showing the out of camera file compared to the processed colour version. And explain why there is a visible hotspot in the centre, due to the choice of Lens. (This won't happen again, i am enjoying the learning curve with these.)

London early morning.

Good morning, 

An images taken from Tower bridge at 04:35hrs. I shot this purposefully knowing that the sun will rise behind me. Some times shooting towards the sun isn't always the best option. I wanted to illuminate the buildings and not cast them into silhouette. As the sun raised it lit up the buildings perfectly just as i wanted. 

This concludes the two weeks of colour London images. 

I hope that you have enjoyed my colour London photos as i have sharing them with you. 

Next week starts 10 days of Black and white images of London.

Morning, 

Thought i would share this image of the Shard building with you. This is a first for me, using an Infrared filter. I ended up purchasing a Hoya R72 filter and am quite enjoying the outcomes. 

There are somethings i need to take into account, the flaring is becoming an issue and the lens hotspot. But with more practice I'm sure ill find a decent work around. 

I am not posting just yet on how i processed this, with this being my first, id like to shoot a lot more and so have a greater understanding of how they react under different lighting circumstances. 

Once i am happy ill write a post on what photoshop process i go through. 

In the mean time i hope that you enjoy this image, 

 

If you would like to purchase the filter that i used, i would be grateful f you use the following link, it will not cost you anymore, but i get a few pence to help feed my family :)

Canary Wharf sunrise, London.

Good morning, 

 

An image of Canary Wharf with the sunrising between the buildings. 

 

Canary Wharf is a major business district located in Tower Hamlets, London. It is one of the UK's two main financial centres – along with the traditional City of London – and contains many of Europe's tallest buildings, including the second-tallest in Great Britain, One Canada Square.

Canary Wharf contains around 14,000,000 square feet (1,300,000 m2) of office and retail space, Around 105,000 people work in Canary Wharf and it is home to the world or European headquarters of numerous major banks, professional services firms and media organisations including Barclays, Citigroup, Clifford Chance, Credit Suisse, Infosys, Fitch Ratings, HSBC, J.P. Morgan, KPMG, MetLife, Moody's, Morgan Stanley, RBC, Skadden, State Street and Thomson Reuters.

Canary Wharf is located in the West India Docks on the Isle of Dogs in the Borough of Tower Hamlets in East London. The West India Docks once formed part of the busiest port in the world. After the docks were closed in 1980 the British Government adopted various policies to stimulate the redevelopment of the area, including through the creation of the London Docklands Development Corporation in 1981 and granting the Isle of Dogs Enterprise Zone status in 1982 In 1987 the Canadian company Olympia and York agreed to construct a major office development on the Isle of Dogs, with construction commencing in 1988.

Tower Bridge, London

<img src="Tower bridge moon.jpg" alt="river Thames luna night scene Lee Ramsden blog">

Nikon D800 f11 13sec ISO100 24-70mm@45mm

Another image of the World famous Tower Bridge in London on the River Thames. Taken at 04:24hrs with a prominent Moon showing. 

 

Tower Bridge (built 1886–1894) is a combined bascule and suspension bridge in London, England which crosses the River Thames. It is close to the Tower of London, from which it takes its name, and has become an iconic symbol of London.

The bridge consists of two bridge towers tied together at the upper level by two horizontal walkways, designed to withstand the horizontal tensional forces exerted by the suspended sections of the bridge on the landward sides of the towers. The vertical components of the forces in the suspended sections and the vertical reactions of the two walkways are carried by the two robust towers. The bascule pivots and operating machinery are housed in the base of each tower. The bridge's present colour scheme dates from 1977, when it was painted red, white and blue for Queen Elizabeth II's Silver Jubilee. Originally it was painted a mid greenish-blue colour.

An image of the London Eye. 

The London Eye is a giant Ferris wheel on the South Bank of the River Thames in London. Also know as the Millennium Wheel, its office name was originally published as the British Airways London Eye, Then the Merlin Entertainments London Eye, then the EDF Energy London Eye. Since Mid-Jan 2015, it has been known in branding as the Coca-Cola London Eye, following an agreement signed in Sep 2014.

Big Ben on the river Thames, London

<img src="Big ben colour image.jpg" alt="London Bridge River Thames City of Westminster capital government Lee Ramsden">

Nikon D800 f13 5min ISO100 70-200mm@100mm

Morning, 

Following on from yesterdays post, this image was taken at 05:20am (the official sunrise time.) As you can see it was an overcast murky looking morning. But there is something i like about this print, the colour tones are what we normally see on a day to day basis. 

This sums up what i love about Landscape/cityscape photography, where it is a gamble. I edge my bets by checking weather reports the night before, i turn up at the location at least an hour prior to sunrise, but you just never know how it will turn out. Some mornings fog comes in and you see nothing, or its overcast and the sun doesn't even make an appearance. 

Not all was wasted though as while i am trying to make portfolio pieces, i am also shooting with the intention to create stock images. An image like this has more financial value as stock than an art worked piece with a dramatic sky. 

 

Big Ben is the nickname for the Great Bell of the clock at the north end of the Palace of Westminster in London, and often extended to refer to the clock and the clock tower.

The tower is officially known as the Elizabeth Tower, renamed as such to celebrate the Diamond Jubilee of Elizabeth II (prior to being renamed in 2012 it was known as simply "Clock Tower"). The tower holds the second largest four-faced chiming clock in the world (Minneapolis City Hall being the first). The tower was completed in 1858 and had its 150th anniversary on 31 May 2009, during which celebratory events took place. 

The tower has become one of the most prominent symbols of the United Kingdom and is often in the establishing shot of films set in London.

A couple of images taken from Jubilee bridge in London of Big Ben, westminster and London bridge on the river Thames. The difference to the colouring is not photoshop, it is time. 

From checking the META data to these files there are 13 minutes difference from when they were taken. Its amazing how fast the sky changes and it can dramatically change the feel to your image.

Alarm set at 3am, drove into London and set up for 4am. 0520hrs sunrise time, my fave time to shoot is just before sunrise, and the time on the above files are 0433hrs and 0446hrs. 

For long exposure images like this, i use Lee Filters. Either the big stopper which is a 10 stop filter or the 0.9 Neutral density filter.

Another crazy ISO3200 frame from a recent timelapse made in London, with tower bridge in the distance, taken on moreLondon property, dodging the security guards... 

I have no idea who the silhouetted man is, but it was a stunning sky and so why not capture it on your phone on the way to the office.
