|New approach to "Most recent photos" [button above]. All explorations of Friesland lately offer great opportunities for photography. The album "Most recent photos" is now aiming to show just that. Pictures in this album will constantly be refreshed and stay in it for about two months. These photos will at the same time be included in the 'Netherlands birding' for 2020 and 2021.|
|June 1, 2021||The second 'Night of the rails' unfortunately delivered no Rails, again. After a first round the field map was empty, without entries! So we decide to go for a second round and towards the end that gave as a Bittern in the northern section; most likely the same one as from the first night a month ago. We were done by 04:00h and went on to 'Grote Wielen' to do a round counting birds for BMP. After breakfast we caught up on a nights sleep…|
|May 16, 2021||Bird counts in Grote Wielen. Just in time we could start doing bird counts for breeding birds in Grote Wielen. Two sections of this 'Natura 2000' area have been allocated to us. The area consists of marshes and wetlands and is very important for birds like Marsh Harrier, Bearded Reedling, Bluethroat, Rail, Spotted Crake and Sedge, Savi's and Reed Warblers. We see and hear these birds often and their pictures are in the album with latest photos. Also and therefore the Marsh Harrier is bird (photo) of the month this time.|
|Apr 24, 2021||'Night of the rails'. This weekend is a nation wide birdcount aiming to simultaneously count all rails, i.e. the Little, Baillon's and Spotted Crakes and the Waterrail. We are counting Ottema-Wiersma, a reserve just North-East of Leeuwarden. The plan was to count around midnight, when these rails are most active. But the curfew blocks that, so this morning we got up at 04:00 to be on our way at 04:30. At that time first light already starts to show on the eastern horizon though. So this gave us a narrow time-frame to count half today and tomorrow morning will be back for the other half. We did catch a beautiful sunrise, wauw… Play this clip with sound to full!
Counting Bitterns is a by-catch of this event, we heard three of them 'humpf' and saw two walking together in the reed bed! Spectacular, because one hardly ever sees these birds!
|Apr 8, 2021||observations.org. Meanwhile the counter is at 170 species since may of last year…|
|Apr 8, 2021||Many photos added to the site. Many new pictures have been taken recently. But we were out so often that there was a backlog of developing and posting these. That has now been taken care of and you can find the 'Most recent images' in exactly that album (button above). Enjoy!
Our busy schedule is not all about plain work or wildlife photography, but definitely about birding. We have taken it upon us to do breeding bird counts in two areas just east of Leeuwarden. Counting breeding birds is very interesting and challenging, but mainly a lot of fun and lots of outdoors. And early days, counting should start well before sunrise…

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.
Focus bracketing is a great feature for creating focus stacks where depth of field is limited. This is very useful for close-up photography, but also in other ways.
Taking the photos. One of the options for bracketing in the PEN-F is focus bracketing. Adjustable settings allow for the number of shots to be taken and the shift of focusing distance in between each shot. More photos allow for greater depth of field in the final image. Equally relevant is the shift in between each shot, and obviously there is a relationship to the aperture used. A smaller aperture allows for larger steps but has its own downsides. There are no rules (of thumb) for this, so testing and evaluating final images must build experience.
Of course the shots must be made with the camera mounted on a tripod. And for exposure consistency using a manual exposure setting is advisable.
Constructing the final image. Merging and blending the photos needs to be done on a proper and powerful computer with lots of memory. Specialized software like Zerene Stacker can be used, but Photoshop also does a very descent job. To date 20 photos were alligned and blended in Photoshop (CS6) and times waiting for PS to finish the job at hand were quite acceptable.
The results are impressive. Some of the first images are posted, see the results in the album Most recent photos. Some of the images can be clicked to compare the 'top' image, without bracketing applied, with the final image.
Meanwhile it is evident that with the camera closer to the subject, more photos are needed for full depth of field.
General. Photos are organized in albums. The 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 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
|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|

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! :-(
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.

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).
