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.

The full moon was 2 nights ago and I tried out the Bigma and 2x teleconvertor. I think I need a new tripod but this was one of the early results. Comments please.

Steve, I think you need to play with the levels to increase the contrast.

Steve, is this as shot or cropped out of interest?

Steve in the past I have used the Bigma to photograph the moon and found that by shooting very early morning rather than late at night the moon appeared to be closer. The Bigma can produce some really sharp images.

The shot is as shot no crop. I have increased the contrast as mentioned - have I overdone it now??. The early mornings are a bit of a trick for me as I am always on my way to work before the sun. :roll:

The contrast is good, but it seems a bit oversharpened with the bright border effect around the terminator at the right hand edge where it should be dark.

The moon wont necessarily be larger in the early morning, it is dependent on if its moving closer or further away in its elliptical orbit, and since it reached apogee on the 13th of March it will be moving closer to Earth until the 28th when perigee occurs, so if you wait from the evening to the morning, it will appear slightly larger, but if you wait until the next evening it will be larger again ;)
Remember too that superimposed on this gradual increase from the 13th to 28th that it is actually closer to you when it is overhead than it is on the horizon, so will appear larger when it is highest in the sky, despite any optical illusions of how big it appears near the horizon.

3rd time lucky - I wish I knew what I was doing here. The black border appeared when I applied the contrast enhancement. I selected the black, slected inverse and the edge appeared?? photoshop quirk maybe.

OK, its getting close ;) The only other suggestion I have is to check your levels for the almost blown area around the crater Tycho, there is a large white area on your image, it may be saturated there, or it may be salvageable by adjusting the curves.
Actually I checked myself and found it is easily fixed:)
