Jan 30, 2017 Working with new Sigma. At the start of this year we went to West Coast NP to watch birds and work with the new Sigma 150-600mm lens. The results are good, crisp images, nice and sharp. The photos are added to the album "West Coast NP" one of the favorite destinations. The Februari 'Photo of the Month' is one of the images taken.
Oct 18, 2016 Latest albums integrated. Most photos in the albums announced a week ago are now integrated into existing albums where applicable. Find them for example in 'Flora', 'Cape Floral Kingdom', 'Insects' and some travel reports. Also the styling errors of the startpage have been fixed so that this page is stable again.
Oct 11, 2016 South African spring 2016. Cape spring is past and many photographs were taken. Also some family was visiting Cape Town in September and we've kept them nice and busy in the available time, visiting most national parks near by as well as the city. We also walked the 'Flower trail' in West Coast NP. Unfortunately that was somewhat late in the season and most flowers were done. Despite that the scenery was colored nice and yellow and we saw a number of beautiful flowers still (picture of the month!). View the album via this link or the page with the travel reports.
Oct 11, 2016 Dutch flora and fauna. Last summer we spent our holiday on vacation in The Netherlands. And this time I photographed quite a bit of the flora and fauna. These images are now on-line and can be viewed via this link.
Sep 12, 2016 Problems with photo editing. Things are not going well this year. The last months were of course very nice weatherwise and it was a great time to go out and shoot many pictures. But it stopped right there because my computer just did not want to start up. I even feared I had to replace it! Fortunately after re-installing Windows and all software it is now up and running again. But I have a serious backlog in photo editing.
Therefore I am only posting an new picture of the month. This one was taken with my new lens, a Sigma 150-600mm f/5-6.3 DG OS HSM Sports Lens. I bought it mainly for bird photography and the first impressions are fantastic!
June 23, 2016 Some older images revamped. Images taken a number of years ago have been reworked and are now presented in a larger format. Also several images were added. It includes images from Ecuador (2001), Florida (2003) and the Andes (2006). Recommended!
May 30, 2016 Some menu buttons changed. As you probably have noticed the menu has changed a bit. By moving the contact information, room was created for the picture of the month. Also the workings of the buttons has changed to improve navigation on the site and to help monitor where you are and have been.
May 25, 2016 Special on carnivores. The special on raptors made me decide to build a special on carnivores as well. Click the icon of the Lion and open it. Or click here.

The index (left) is by family and/or genus. Species are listed in the right column, per page and sorted alphabetically by their latin name.

Nature is wonderful. My love for the natural world has been educated since I was a young boy. Through the years, whenever and wherever, I will go out to enjoy the wonders of the wild. And as long as I've been taking photographs my preference has been this wildlife, mainly to relive those moments again and again. In time I learned that others enjoy my photos as well. Therefore I decided to make my images available through the internet.

Human impact on nature. The natural world is a vulnerable world and humanity has an enormous impact on it. Not only is climate change a 'hot' item, what to think of that plastic soup that has infested our oceans! Or how about poaching! Wherever you see a Rhino-button on this site, click it to see the status of poaching of these fantastic animals. Another example: every day vast areas of primeaval forest get axed by logging companies and with them the wildlife that populated these forests disappears.

All these horrible things happen because a few selfish, ignorant pigs seem to never have enough money!! And for sure, for many people it is just their way to suvive day by day, but it is not just that. Rhinos are killed for BIG money, elephants, tigers, forests are cut down, the list is long… We can read about it or watch programs on this subject on the tv. Please visit the website of WWF to see how extensive the impact of humans is and what they do to help conservation. And how you and I can help their work!

I've seen it with my own eyes… It is heartbreaking!

Improve awareness? I believe somehow, that showing the beauty of the wild world may help to improve awareness. Hopefully not in vain.

'Photo' vs 'Image'. In my view the words 'image' and photo' have a different meaning. To me a 'photo' is what the camera takes, an 'image' is what the photographers creative mind intends with that capture. Sometimes I need to take several photographs to capture the image I'm seeing. Sometimes I can even digitally create the image I wanted. Panoramic images are another example, as some photos are digitally 'stitched' to ceate a panoramic image. The result then is strictly speaking not a (single) photograph but definitly the image I intended.

How are those panoramas made? If it all possible the camera is placed on a tripod with a level. The exposure setting should be 'M', manual' and all photos taken with the same setting to make sure they have the same exposure for a smooth blend. I then take the required number of shots, each with an overlap of about 1/3. Back home I 'stitch' these together with a pixel-editing program.

Special albumview for flora and birds. By clicking the button [Flora and birds] albums can be viewed in a non-standard way. Also a large number of extra bird photos can be viewed. These extra photos are primarily 'registration' type and for the interest of birders. The quality of the images does not always meet my photographic criteria. Sometimes they are not sharp enough, or they may be zoomed-in too much and not contain enough pixels. Or they just are not nice enough, they are not photogenic. However, I have put them on-line anyway, because I know many birders might like to see them in any case. I have also provided special search pages to easily find an image of a specific species. [new] The album 'Cape Floral Kingdom' can now also be viewed in this easy but non-standard way by clicking [Flora and birds] and choosing the third tab.

Colour scheme for bosfoto.nl. Coloured backgrounds are distracting and influence color perception of an image on that colour. For unbiased viewing, images should be presented against a calm and neutral background, i.e. shades of neutral grey and black.

General. Photos are organized in albums. The Portfolio's section of the menu offers different ways of selecting an album. After selecting an album a second window will open to show that. The buttons under Information give you all kinds of info about the site, myself and my gear and more.

Choosing the option [Flora and birds] reveals a lot of specific bird related stuff. There is a tab to view bird photos available, including an album with images of a lesser quality, just birds… Also two ways of finding photos of a specific species are available. [new] The album 'Cape Floral Kingdom' can now also be viewed in this easy but non-standard way by choosing the third tab in this option.

Findig your way in the albums. The left side of an album page is the selection zone. The top part is a pull-down menu with all the other pages in that album. Photos can be selected from the pane with the thumbnails. Navigate the album in three ways: using the thumbnails, the keyboard or the buttons below the image displayed.

Albums can be viewed one-by-one, in a slideshow or in an continuous slideshow. Select a different viewing mode using the icons along the top-right of the thumbnails.

When this camera appears to the right of the navigation controls, an additional image is available. Directions for seeing it will show-up (in yellow) below the buttons.
This symbol top-left is an indication that the current image does not meet my normal standards of photo quality. Further reading on this in the previous tab [On the photos]
This button opens quick 'help' panels that give a lot of details on navigating the albums. Pressing 'i' or '?' while viewing photos should give a pop-up with more comprehensive help

For building this site and keeping it up-to-date Adobe Dreamweaver is used. Adobe used to include the 'Spry framework voor Ajax' (read update below!). Spry combines JavaScript and XML in a clever way such that webpages adjust dynamically. All relevant info is stored in xml (computer) files. This in turn is placed on screen and changed with fairly simple Spry-commands. Practicaly speaking this means that on this website, just one mouseclick on a thumbnail replaces the image and all relating information, without changing the page itself.

Spry is ideal for webdesigners (like yours truly) who only have basic knowledge of html, javascript and xml. Thanks to Spry I was able to build this site.

Update mid 2012. Adobe decided to no longer develop and support Spry. An extremely disappointing and frustrating decision resulting in lots of (obviously fruitless) protests on the internet! People (myself including) are angry at the policymakers at Adobe. No more work will be done on Spry and all the documentation was removed from adobe.com and parked on a 'sharing' site called 'github.com'. It seems to me that the greed for more money has taken over at Adobe. Ugrades were only available (annually!) if one didn't skip one, or else pay a full new license! After Dreamweaver CS6 a new version is only available for an expensive subscription to 'The Creative Cloud' (in 2012 € 61,50 per month!!). They must have really big wallets over there and no longer seem much interested in customers, no, it seems shareholders are the important player out there. (Yes, I am not happy!)

Here are some links to information on Spry and some samples (I removed the link to Dreamweaver for obvious reasons: I'm now staying away from sponsoring Adobe and its shareholders! :-(

About Dick Bos [1949].

Because of his love of wildlife and the natural world Dick's junior ambition is a career in natural or environmental management. However, he needs to 'serve his country' first and he then qualifies for pilot training. After graduating from Military Academy and pilot training with the Candian Armed Forces, he is awarded his pilot wings in December of 1973.

His military career takes him to many airbases in many places. He holds several command postings, like squadron and station commander. Dick climbes through the ranks up to one-star general officer. He retires from the Air Force in 2005 at age 55. His pilot logbook totals well over 4000 flying hours on several types of jet aircraft as well as helicopters.

His love of the natural world never fades. And he develops another passion: photography. As a teenager the first camera Dick buys is an Olympus Trip-35 compact. He gets himself a true Nikkormat SLR in 1972 and he has never failed the Nikon brand since.
[Check-out his gear in the 'Gear'-section] Through the years Dick travels a lot and makes many a photo.

Loving both nature and photography results in quite a number of beautiful wildlife images that you can check-out on this site. And now that he is retired, Dick is devoting a lot of his time to these passions. He is co-founder and chairman for many years of the regions chapter of the Dutch Wildlife Photographer Association, in 2014 he was appointed 'honorary member'. He is a member of the birds working group Meijendel and the Cape (Town) Bird Club, participating in bird monitoring programs. He is also the webmaster of the site of the Meijendel birding group.

Some of the photographers that inspire his photographic efforts include Ansel Adams, Eliot Porter, David Muench and Frans Lanting. For bird photography his favorite photographers are Arthur Morris and Albert Froneman.

Prints. All images shown on this site are for sale. If you would like to order please contact me either by e-mail or phone.

Expositions of images on this site can be arranged on request and in consultation. Pricing will depend on the duration of the exposition as well as framesizes and number of images. Are you interested then please contact me.

My work has been on display in expositions in a number of places including my former hometown of Delft. In 2010 many bird images have been on display for 6 months in the cafe of the Dutch Military Aviation Museum. Click here for an impression.

Presentations of my work. I would be more than happy to do slideshow presentations of my work. If you are interested contact me to discuss the details.

Wildlife photography has been a part of me for over forty years. I would like to share my experience and could give presentation(s) on a number of photography themes, all subject to consultation. An example of a presentation (in dutch) for clients of Habari Travel on their open day can be viewed on-line: 'Op safari met Habari'. Please note that this pdf does not include the photos used in support of the presentation.

Digital image processing. I have used Adobe Photoshop for more than a dozen years, from version 5.5 onward, mainly for image processing and manipulation. I would be quite happy to share my experience, preferably not as a classroom effort, but "made-to-measure" for one or two persons.

Digital Asset Management (DAM). Since the introduction of digitial photography loss of images (computer crash, disk failure!) has been a serious threat to photographers. For years I have been using a reliable system in my digital workflow, partly based on the books of Peter Krogh. I am available to share my experience with others. A presentation in dutch can be viewed on-line. Duration of this presentation is about 1,5h.

Costs will be mainly to cover travel expenses and for renting a projector (if required).

Contact via e-mail or phone.

Image restauaration. I have been successful in repairing several damaged or washed-out prints and old photos. I may be able to repair your dear but deteriorated or damaged photos, all or in part, to an acceptable quality.

Pricing will mainly depend on the amount and type of damage and the work to be done. Please note that repair may not always be (fully) possible.
