Focus on D200
-
Hi, I was out at the weekend with my new d200 at fota wildlife in cork. I took a lot of photos but not too happy with the sharpness. Here is an example attached. Has anyone any tips on the best focus methods for the D200? I used auto focus for them all, or is this photo acceptably sharp and am I just been picky?
Hi Ciaran,
I have a D200 also and haven’t had a problem but did notice when I got it that it wasn’t immediately as sharp
as the D70 I had before. This was because the D70 did more in camera sharpening that the D200.How much sharpening did you apply to this in say the raw convertor (assuming you used one) and in your post-processing
software ?thanks
first of all what lens you using?? this can have a massive impact
secondly are you shooting raw or JPG
if raw then you have to sharpen in post processingwhat kind of autofocus were you using it could be that the focus is in oneshot mode, ie it locks on thenif you or subject move the focus will not then be locked

I actually didn’t apply any sharpening for this photo as I just wanted to demonstrate my problem. Maybe I’m expecting too muc from the camera

It was the 300mm length of a 70 – 300mm nikkor lense, not VR unfortunately. I think you might have hit on my problem, I did shoot RAW format but didn’t realise I had to sharpen it in RAW. I was justtrying to get the best results from the camera without any post processing. I’ll know in future, thanks
I have a D200 and used to use the 70-300 Nikkor before upgrading it. This camera and lens is capable of creating sharper images. (for your own ref the 70-300 is a great lens until about 200mm after this it gets soft)
What shutter speed did you use? This lens at 300mm will have an aperture of 5.6 which can sometimes bring the shutter speed right down so you might not get a sharp image
Also it looks like the lens might not have focused correctly. Set the focus to the C setting and keep the shutter button half pressed so that the lens keeps shifting focus.
Would be nice to see a 100% section of one part of the image as its very hard to see with a 600 pixel wide thumbnail of the whole image.
Very nice pic though

Couldn’t resist a bit of a fiddle. I will delete the images if you wish.

After a bit of PhotoShopping:
now that looks a lot sharper, although i would say it seems to have a slight magenta colour cast
That makes a great improvement, thats the effect I’d like straight from the camera! The colour cast might have something to do with shooting through a wire mesh fence, I focused it out as much as I could.
yea by their nature cameras dont produce images that sharp, you have to do it after. BUT if you use photoshop you can just set up an action to sharpen the image, i do that all the time
actually if it was the fence that was causing it it would be in the first version
did you play with the levels too as i notice a huge change in contrast. if you did it using the channel mixer you could of created it in photoshop
a good trick in photoshop is:
go to the histogram, click the little button on the top right corner of it and select expanded view
then at the top of the histogram there is a drop down menu, select colours from there.
now if you see one of the colours sticking out the right hand end of the histogram it is a colour cast.
the way to fix it is to apply a photofilter with the negative of the colour cast. ie if its magenta apply a cyan filter.
then just keep adjusting the level of the filter till all the colours are equal at the end of the histogram. then you have removed it
I don’t think I edited any of that original photo, unless I did something by accident, I have adobe lightroom installed recently and I open my files through that, maybe there is a preset action that could be effecting my photos, I have a suspicion about it, I’ll check it out now that you seem to think it was altered too. Thats a great bit of advice on photoshop, I’ll be sure to save that, thanks
