Teachings of Bill
#2 for me, but I would crop out the distractions at the top and concentrate on the leaf in the middle, poss worth a much tighter crop as well. This makes it my favourite with number 5 coming second. I particularly like the grain effect. You appear to have a hair on your sensor in number one (bot...

i tried 'SPOT Metering' on my PENTAX 6x7 Mk II
Indeed Ansel Adams spent a lot more time in his darkroom than he did taking pictures. Using Photoshop does not by itself render an image fake. I need to use it (or another converter) if I process raw images. I also see the use of selective dodging/burning as a means to create the image that looks mo...

Stigma
A wild and weird experiment with extreme macro. It's the stigma of a flower on one of Mrs L's African Violets. Stack of 20 images taken with a Q-S1 attached to Pentax Auto Bellows A with a Laowa 25mm 2.5-5x macro (at 2.5x) on the other end. Back of the bellows moved to shift focus. Magnification...

A Very Yellow Macro
Another wild and weird ultra-macro. It's the tip of an anther of a flower on one of Mrs L's African Violets (the same flower as yesterday's stigma). Magnification at sensor about 10x (possibly more). The yellow background is another (OOF) anther. A stack of 90 shots. It won't win prizes for sharpnes...

Pentax K1 records Donegal in Timelapse
Thanks for all the kind comments, much appreciated. Living in Donegal, which is one of the wettest and windiest parts of Europe, it can be hard to capture timelapses. Capturing sunrises and sunsets can be frustrating as often nothing happens in sky and you have to go back another day. Wind often...

Learning new tricks...
Interesting. But aren't you losing resolution compared with stacking still images as video is HD (?) rather than the full pixel resolution of the sensor? It does look like there's lots of detail, but is that real or is it perception due to strong contrast and sharpening? And that bright rim is surel...

More Flowery Shots.
Interesting. I've had a look at the apertures chosen for my recent photos of small(-ish) flowers (geranium etc.). They were mostly f5.6 or f8, when the intention was for the entire flower to be pretty much in focus, mostly f2.8 or f4 when I wanted only a specific part of the flower to be in focus. T...

Gaia
Impressive - particularly when you can't see what's holding the earth up :shock:. Is the blue/purple lighting on the column and roof part of the 'art'? It would look a lot better without it IMHO. The shift lens has worked nicely. Any idea whether the K3iii's tilt correction could have achieve...

Hi Steve, As regards the purple, I'm not sure if it is "part of the art" of just the glow of the globe. I could try and edit it out. I have no idea if the sensor shift would work that much. I've never tried it, just stuck to using my shift lens. Best wishes, Kris.

Intentional Camera Movement
Others probably know more:roll: but I will try an advise. A prime lens helps usually 50 mm or 35mm at f12 and beyond A slow shutter speed yes but more like half a second to an eight of a second depending. When pressing the shutter release try to hold the camera steady for the initial opening and...

Hot Men, Hot Women
Thanks. The light was rather tricky, but full marks to the K3iii. Av, -1EV to protect the highlights and let the camera do the rest. Plenty of scope for pulling detail from shadows (RAW files of course). It wouldn't have been possible with my first DSLR (K20D, still have it), I'd have had to sacr...

Camera Lens DSO
Lasst week I decided to go full on camera kit with a deep space object. The target for the night was the Heart and Soul Nebulae. So I attached my K-S2 to my SIgma 150-500. Then I slapped an 86mm Light Poluion Filter on. It was then mounted on my EQ5 tracking mount (not guided tho), and pointed at...

Camera Lens DSO
Beautiful image, awesome outcome! Just wanted to ask. Have you used the Astrotracer feature before? I was looking for a different type of mount at one point but never got around to it. Yes, I did.... and l couldn't get on with it. It cannot handle bigger lenses without visible star elongation. Al...

Absolutely stunning, both the image and the thing itself. And at x9 on the sensor, it's a great technical achievement. Love it! :D:D Steve

Lone Survivor.
You've got that flower spot on :D. I find it difficult to get flowers of that colour looking right with a K3. Lighting? Camera? Sensor? The brain behind the viewfinder? I've no idea**. But I'm pretty sure that I wouldn't have been able to get the flower looking so good. Steve ** Please don't tel...

ICM reed beds, sky and bank side
As the title says, this is an ICM image, no digital textures and the image is as the camera captured it on the sensor Pentax K1, D FA 24-70mm and 10 stop filter by , on Flickr

Elgol - Isle of Skye
These are a superb set Antony - that last image is beautifully composed and executed with that slightly misty water, the second shot shows excellent processing skills in addition to another nice composition - they are all so enjoyable and an excellent standard! If you want really picky criticism the...

Over a few days
For the uneducated amongst us........ Why merge 5 exposures? The idea of HDR merging is to take photos at various exposures so you have detail in the shadows and highlights. Thereafter you can bump shadows and reduce highlights beyond the usual capability of the sensor, or without introducing add...

Holy Smeg!!!! Up in the sky...
You get a sense of the colour rather than an actual vivid experience. I could certainly make out the redder regions against the green ones last night despite being close to a city centre. The detail that you get with a sensor isn't there though. The time lapse was taken with a Pentax DA 10-17 on ...
