Background blur / bokeh on a natural subject: variation with aperture - OMD EM10ii + 45mm f/1.8.

Image
Effect of aperture on background blur / bokeh effect on a natural subject - OMD EM10ii + 45mm f/1.8. Successively taken shots f/1.8, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16 and f/22 (except that f/2 was actually taken last for completeness but I placed it second in the column of photos where it should go). This series shows well the compromise that you might have to make between getting an aesthetically pleasing blurred background effect and not actually having parts of the subject out of focus. This honeysuckle flower has petals pointing to and away fro the camera and, with the lens wide open, parts of the flower are out of focus. This in itself can be a distraction. In this case it seemed best to focus on the buds / seed pods and the most detailed parts of the picture to get a pleasing shot. It is not until around f/4 that the whole flower is in decent focus but a lot of the bokeh effect is lost by then. This would not be a problem if the subject was flat with all parts equidista...

Shooting modes / art filters and their effect on a subject - OMD EM10ii + 45mm f/1.8.

Shooting modes / art filters and their effect on a subject - OMD EM10ii + 45mm f/1.8. Firstly Natural Colour mode, then all the art filters from 1 to 14, Pop Art to Partial Colour - but I didn't choose a colour for partial colour so it came out black and white! Natural Colour Then the ART filters ART 1 - ART 14: Pop Art (pink background blur goes to reddish tone)  Pop Art (Art 1) with green background this time Nice bokeh here at f/1.8. Soft Focus Pale & Light Colour Light Tone Grainy B&W Pinhole Diorama Cross Process (very green!) Gentle Sepia Dramatic Tone On these later pictures the background blur circles are smaller so I might have stopped down a little here Key Line Water Colour (always came out very bright) Vintage Partial Colour (with no colour selected) Partial Colour taken later with orange/red tone selected

Varying depth of field and background bokeh effects from 45mm f/1.8 M.Zuiko lens on OMD EM10ii.

I hope to show in the next couple of posts some examples of photographs of a nearby foreground object, a simple early autumn late blooming honeysuckle flower in my garden against a background comprising of other garden plants at various distances behind it. Firstly, I went through the OMD EM10 Mark II's main shooting balance options and art filters, all shot with the 45mm f/1.8 lens wide open at f/1.8, exposure times approximately 1/2000 second on a bright day. This gives an idea of how the art filters might affect a natural subject and also how they affect the colouring of the background blur. Secondly, I then I did a brief study of varying depth of field and how it affects the perception of the picture through background blur at apertures between f/1.8 and f/22 on the 45mm M.Zuiko lens, which is already one I love to use. With this subject as with many others, there is a trade off between the pleasing bokeh effect of well blurred background colour wash that brings the subje...

New lens - 45mm f/1.8

Image
Got a new lens today, the M.Zuiko 45mm f/1.8. Tiny and very nice. I really shouldn't have! I had a quick try with it today but need to do more to get used to it. All photos were taken at f/1.8 (wide open) or close - to get minimum depth of field, just for a try. Not great compositions but these are the first day attempts in the garden, almost straight after opening the box. Nice lens. I like it. No processing on any of the pictures except a little cropping on all of them and light sharpening on the last closeup spider picture.

85mm f/2 Zuiko MC lens bought around 2001.

Here is a pic of my 85mm f/2 Zuiko MC lens bought around 2001. Not for sale, at least not until I try it adapted to my new OMD EM10 Mark II! With the tiny and gorgeous 21mm f/3.5. This just makes me want to go out and buy some films!

Olympus OMD camera user / fan site.

Hello and welcome to my OMD camera user site. This is just me with a modest Olympus OMD EM10 Mark II and three lenses. So far I have the twin zoom kit 14-42 EZ kit zoom, 40-150 kit zoom and Panasonic 25mm f/1.7. Some comparisons of the 14-42mm EZ kit pancake lens set to 25mm with the Panasonic 25mm f/1.7, with both lenses set to f/5.6. These are all 100% magnification on-screen crops from shots of about half a page of a document, right next to the closest focusing distance of the two lenses. First up the cruel comparison. I think the 14-42 (left) was right at its minimum focusing distance and perhaps I moved the camera slightly. Anyway, the 25mm f/1.7 looks a lot better but I may discount this comparison slightly in favour of the two below it. However, these were "first shots" so I am showing them here: Second, more shots (different ones). Which were taken by the 25mm f/1.7? here I retreated just a little bit from the minimum focusing distance to make sure I didn'...
