I took the new (second-hand) lens out into the garden to try to capture a closer shot of the moon than my very old 75-300mm lens used to allow. I stacked three of the clearest shots in Z stacker. I’m not sure how effective that was, as the stacked final only looks marginally clearer than the original sharpest image. I have compared it with an old shot of the moon I took in September with my old 75-300mm lens.
I’m looking forward to taking more images of the moon, on clearer night than this (it was a bit hazy).
The original images (below) was f/9, 1/100, ISO 100, at 400mm on a semi-cloudy night.
STACKED. Canon 100-400mm lens. Three images stacked. 28/12/2017.
OLD. Canon 75-300mm lens. f/5.6. 1/250. ISO 100. 02/09/2017.
I went out into the field to try to catch some action shots of the Red deer and Fallow deer in Calke park, Derbyshire, as the males begin to demonstrate sexual fitness in autumn, select mates/mate and defend harems. I didn’t manage to catch any rutting on this occasion, although there were a couple of individuals with obvious wounds from fighting, and plenty of strutting about and bellowing taking place. I did find some sleepy individuals who were obviously not interested and for whom it all looked like far too much drama and effort! Other individuals were busy practising locking antlers with low hanging branches of trees and rolling in mud, and running around a lot looking quite magnificent.
Having read up a little on noise in close up shooting, today I kept the ISO to 400 or below and shot some images. I noticed that it was almost impossible to get a really sharp image (suspect as I was handheld only, but I can shoot sharp close ups by hand normally). I’m guessing this is the pay off somewhat with close up settings.
Hand held: f/5.6, 1/320s, ISO 100, 47mm focal length.
Later on I took this image – handheld, but changing the settings to f. 8.0, 1/640s, ISO 1000, 35mm. Still a low aperture to isolate the subject, faster shutter, sharper image. But look at that background noise.
Still, that’s why we have PS – to reduce noise, amongst other things! See below.
The background in the above image has been subjected to noise reduction in Photoshop. It looks less grainy (noisy), but the object loses some of its sharpness too. It seems to be all about pay offs between settings. I guess I’ll use a tripod more often and stick to a low ISO.
I’m a keen gardener and even keener when it comes to growing roses. David Austin roses are some of the best. During the summer months, I took a number of photos of my roses (having built a special rose bed). I used close up pre-settings, mostly, to see what kind of results I could get. No macro lens – just the EF-S 17-85mm f/4-5.6 IS lens that comes as standard with the body of my camera. Here are a few shots from the summer.
