What's happening around the subject matter here? I'm seeing what appears to be a grey smudge all the way around this, and for me, that detracts from what you've done.
Can you increase the light output from the flash on this? I suspect that this is a larger subject than the spark plugs, and you have a greater area to cover/include in the image; depth of field seems to be suffering as a result. I think it might be better if there was an extra stop or two of light, which you could then counter by modifying the aperture setting to compensate, resulting in an increased DoF.
The level of detail, and the acuity, that you've achieved here is superb, but my observations described above detract (for me) from what is otherwise great work.

Has that improved it ?, yeah i didnt change lighting after plugs and it could have been turned up along with a larger Fstop

Posted: Mon Dec 05, 2016 7:36 amI cant see the greyish area on the first one but i know exactly what it is, because i turned up the exposure in lr it ligtened the background and i wized around with a brush to bring it back.

you are in the ball-park with these but this shot requires a smaller F/stop to bring the front sprockets into focus. With technical images like this, (industrial photography), it is important to show the whole subject in focus.

these get confusing.
I needed a larger F/number and smaller apature is what i meant by larger fstop.

yup I agree, cool subject, but it all needs to be in focus - if you can't do it it at f20 then focus stack

Exactly.
And interestingly, I cannot see this on one of my laptops, but most certainly, on my desktop, thar she blows.
Yes, the second of these is better from that perspective. Now to go back, add more light, and then use a higher (numerically) f-stop.
