  1. Hi Ari - if you zoom in on my first image (as I clearly failed to do!) you can see that the blue pixels in the sky actually vary quite considerably in brightness giving a speckled effect. This usually happens when the ISO / gain is too high and the sensor isn't getting enough light to calculate the "proper" colour and/or brightness value. This image was shot at a low ISO but the shutter speed was very high (1/1600) because I'd been shooting a motorbike race and just lifted the camera to snap the chopper as it passed overhead. The end result is the same, not enough light on the sensor. If I'd shot at a lower speed as Steve suggests above then I'd have more light on the sensor and therefore a less noisy sky and the bonus of blurred rotors to give a sense of movement. To "fix" (actually just reduce the effect) I used the "noise reduction" facility in Adobe Lightroom which effectively averages colour and/or brightness in a group of pixels. This has a side effect of reducing detail. The correct solution is to shoot at the correct speed and exposure so instead of ISO 400 and 1/1600 I should have used ISO 100 and 1/400. Alternatively 1/400 at ISO 200 would let me lose one stop from the aperture and get a bit more DOF.
  2. Thanks Kelly - I'll try that too.
  3. A big thank you to everyone that has taken the time to give me feedback on my images in this forum and privately too! It is much appreciated and I'm determined to improve :-)

    Yes - you are right about the twig. I was going to move it but as I raised my hand the kitten jumped at it and then ran about the garden

    OK - I understand. Thank you for your advice it is very useful
  8. Image lightened and sky de-noised:
  9. You're right - pretty much everyone would be able to recognise themselves. Only suitable for editorial.
  10. Apart from that... is there any hope for this type of image?
