Got a thin skin? Then look elsewhere. Post a link to an image that you've made, and invite others to offer their critiques. Honesty is encouraged, but please be positive in your constructive criticism. Flaming and just plain nastiness will not be tolerated. Please note that this is not an area for you to showcase your images, nor is this a place for you to show-off where you have been. This is an area for you to post images so that you may share with us a technique that you have mastered, or are trying to master. Typically, no more than about four images should be posted in any one post or thread, and the maximum size of any side of any image should not exceed 950 px.

Forum rules
Please note that image critiquing is a matter of give and take: if you post images for critique, and you then expect to receive criticism, then it is also reasonable, fair and appropriate that, in return, you post your critique of the images of other members here as a matter of courtesy. So please do offer your critique of the images of others; your opinion is important, and will help everyone here enjoy their visit to far greater extent.

Also please note that, unless you state something to the contrary, other members might attempt to repost your image with their own post processing applied. We see this as an acceptable form of critique, but should you prefer that others not modify your work, this is perfectly ok, and you should state this, either within your post, or within your signature.

Images posted here should conform with the general forum guidelines. Image sizes should not exceed 950 pixels along the largest side (height or width) and typically no more than four images per post or thread.

Please also ensure that you have a meaningful location included in your profile. Please refer to the FAQ for details of what "meaningful" is.

Dave,

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.

I 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. :cough: :cough: :cough: :cough:

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. :bowdown: :bowdown: :up: :up:

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 :)

No amount of processing will fix bad composition - trust me i have tried.

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.
