LOL what a joke winterrose. You are so transparent its almost ridiculous.
Someone new arrives on the scene, someone who appears to be balanced and know what they are talking about, and immediately winterrose adopts a reasonable demeanor with everyone.
And goes from abusing and insulting christo in every post and calling him a bogan to trying to appear like Mr Niceguy.
Get real rob, all your previous posts are still there.
I assume the new guy has read a lot of them.
You don't have to pretend.
You can continue to show your spots.

Iran deal:

The nuclear-related agreement signed between the PS +1 and the Iranian government is, on its face, one-sided. In essence, as detailed by Senator Mark Kirk (R-IL), they get: billions in sanctions relief, 3,000 new centrifuges, a plutonium reactor and enough enriched uranium for one nuclear bomb, for now.

We get, essentially, nothing. No centrifuges dismantled; no uranium shipped out of the country; no facilities closed; no delay at the Arak plutonium plant; and no stop to missile testing, terrorism or human rights abuses. But it is, actually, worse than that.

The administration’s position is that the nuclear deal is separate from any other conversation with Iran, including the fate of Americans imprisoned there.

Do you mean how much editing is allowed before the image is posted or how much is allowed after the image is posted?

The OP can do whatever he deems necessary in post to "finish" his photograph.

No edits are allowed in the PC&A Section once the finished photo has been posted. If the photographer wants to do post work then he needs to do it, and post the edited image in a new thread for critique. If he needs help in post, he should go to the Post Processing Section for help.

I would like to say something about Graham Smith. While many view him as this professional, expert photographer, Graham does not view himself that way at all. He sincerely looks forward to the feedback he gets on the photos he posts. He is very humble about it, he doesn't brag, he doesn't self promote. I wish that the people who think he is just posting to get a pat on the back, and publicly say so, would take the time to get to know him a little before making statements about him that simply are not true. Yes I think he is an amazing photographer. Many others think he is an amazing photographer.

But, do you know who else is an amazing photographer? PhotographerJim. He places his images in competition. But even though he is very good, he likes to put up an image in the Critique Section for feedback. He has gotten some very useful and helpful feedback. No matter how good you get, it is still nice to have some other points of view on your work. No matter how good you get it is still a hard thing to be objective about your own photos. So please. Quit picking on the talented photographers that post in the Section. They deserve feedback as much as anyone who is just starting out.

Again, Crititque is not Criticism! Critique is the evaluation of an image, good and bad, on the elements that make up a photograph. There are 12 of them listed in the PC&A Section. Here they are again!

1. IMPACT
2. TECHNICAL EXCELLENCE
3. CREATIVITY
4. STYLE
5. COMPOSITION
6. PRESENTATION
7. COLOR BALANCE
8. CENTER OF INTEREST
9. LIGHTING
10. SUBJECT MATTER
11. TECHNIQUE
12. STORY TELLING

All you need to do is to give some feedback on these elements. You can give positive feedback in a critique, as well as negative feedback.

Icebergs in Lake Winnipeg (Province of Manitoba, Canada) sometimes have stripes, formed by layers of snow that react to different conditions.

Blue stripes are often created when a crevice in the ice sheet fills up with melt water and freezes so quickly that no bubbles form.

When an iceberg falls into the lake, a layer of water can freeze to the underside. If this is rich in algae, it can form a green stripe.

Brown, black and yellow lines are caused by sediment, picked up when the ice sheet grinds downhill towards the lake.
