I've checked the shot & there is a slight magenta cast to it, I've corrected it - here's the new version.

Processing wise I've not done much but I have just upgraded to CS4 and tried out the new gradient tool in ACR on this to add a bit more detail to the sky, perhaps the original post was a bit overdone, I've toned it down a little in this repost, I've also cropped the shot slightly on the right

A while ago I was fortunate for someone to lend me a 1.4 TC to try with my Pentax 55-300 (the best consumer zoom available in Pentax mount imho), it was the "legendary" Tamron 1.4 PZ AF.
After quite a few tests I quickly decided that a TC wasn't a good idea - image sharpness was noticeably affected at 240mm+ but even more significant was the loss of light and it's effect on autofocus performance. Personally I think TC use is best limited to faster glass

Could you just clarify - you say ALL my images, do you mean those on my website too ?

thanks

Simon

Thanks both for the comments/feedback,

Howard, as George mentions, it was a bit of a struggle with the DOF - the lighthouse was quite a distance away so I had to use a focal length of 50mm to try & bring it closer, this obviously made it even more difficult to achieve the sharp heather in the foreground so in the end I compromised with a slightly softer lighthouse.

I might be able to sharpen the lighthouse slightly with a bit of PP - I'll have a go

This is a shot I've been thinking about for a while now, the summer heather on Anglesey adds a new dimension to some locations and with the recent awful weather I was beginning to think that I'd miss the chance as it's not in full bloom very long.

This was taken yesterday whilst hiking the coastal path between Holyhead & Trearrdur Bay, if weather permits I'm planning a revisit nearer sunset.

BTW, this is my 1st real landscape shot with the K20D/Pentax 17-70.

I'm just processing some shots I've taken recently which have quite strong colours, when I open the image in ACR and use [alt] with the "black" (shadows) slider ACR shows yellow patches in the image, reducing the black slider makes a slight difference but not nearly enough

This seems to be a colourspace issue as if I change from Srgb in ACR to prophoto the yellow areas disappear - Argb makes little difference

Would appreciate some advice on this

thanks

Simon

Just bought one myself and although I haven't had chance to use it much (due to the UK weather !!) I'm very pleased with it compared with my previous Sigma 17-70

simon

Thanks again everyone for the generous comments, much appreciated

simon

Definitely worth getting, excellent lens..a little slow to focus in low light but other than that it's the best consumer zoom you can get for Pentax by some margin

simon

Thanks everyone....the shot was taken in December during sunrise, it was much colder than it appears - worth it though !!
