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.

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.

A little too tight for me Manta. Perhaps the DOF needs to be back a little to get the keys more in focus.

Cheers,
owen.

Thanks Owen but I wasn't intending to achieve a balanced shot, just wanted to try a demo to clearly show the effect. :lol:
I took several more at varying apertures but they were just..well...photos of a keyboard! :wink:

I've found a book lying open is a good way of showing the DOF effect. That way you can clearly see what text is sharp and what is out of focus, perhaps the letters are too far spaced apart on a keyboard to really show the shallowness to it's full effect? Just my opinion anyway :)
