icerock 0 Posted March 25, 2005 What causes aurora? Aurora occurs in an oval donut-shaped area called the auroral oval. The Earth has one such oval above each magnetic pole. Actually you have to be inside the "donut" to observe the aurora - on the poles them selves you wouldn't see these amazing lights. "Aurora borealis" means northern lights, but the southern ones are called "aurora australis". Where and when? The best places to experience aurora are at the edge of the Arctic (very accessable unlike Anartica). Aurora borealis are most frequently seen from: - Northern parts of Finland and Norway including Svalbard. - Iceland. - Greenland (especially mid-Greenland). - Alaska and northern parts of Canada. - Northern Russia (Siberia). On very rare occasions the oval can cover the entire northern hemisphere - all the way to Mexico. In fact this happened in November 2001. Note that it is impossible to see the aurora during summer - then it never gets dark enough in the arctic areas. The "aurora-season" goes approx. from late September to late March, when the sun doesn't outshine the aurora. And for some unexplained reasons the aurora is generally most active in late autumn and early spring. Link to comment

marcadamus 1 Posted March 25, 2005 Spectacular photo! WOW! One of the finest Aurora captures I've seen. A science lesson too! I'd be tempted to try to capture it's refection in the water too, but this is exceptional! 7/7 Link to comment
giuseppe_miriello1 0 Posted March 25, 2005 Congratulations. The image correctly conveys the story, it is dark but with details in highlights, so we have an intresting dark landscape that does not compete with the primary subject. A bit of details (sharpen) could be useful in the foreground ice - but is not necessary. It is also intresting that stars appear quite still despite de exposure (which probably was long - but how much exactly?). The added expanations are always welcome, i try to do the same myself but i admit you have been extremely clear and also gave useful informations to those who never approached this subject. For all the reasons above i give you a full score. Regards. g. Link to comment
icerock 0 Posted March 25, 2005 Thanks for looking in on my picture, It is hardly not possible to use digital in aurora photographic it is not handling the work, next winter I will use film I need to get a short exposer as possible so iso 200 and 4-6 sec if possible. also I did take a short look at your sight and you are dam good in B&W I will look in on you when I have good time :) Icerock Link to comment
mar_lia_ferraz 0 Posted March 26, 2005 Longing to be there, one day, my friend.I can only imagine how it is to shoot aurora with such a great details.I love to travel to Iceland with you.Hugs,Marilia Link to comment
naty_z 0 Posted March 26, 2005 our friend Cris told me about his wonder when he saw the aurora, he was really lucky to see it! I can only see it in your wonderful photos, this one is absolutely magic, just like it was from a fantasy world! Link to comment
giuseppe_miriello1 0 Posted March 26, 2005 I got your point on the exposure. Many photographers could suggest fuji velvia or provia, these are excellent when it comes to huge saturation, fine grain, high details. I don't know how digital may handle the exposure, i knew digitals had problems in rendering details in high lights, but maybe new cameras may have solved the issue. 2-4 or more seconds may not effect star's rendering but some try should be done to get how much plus details you get by closing f-stops and how much the aurora gets fuzzy by the longer exposure itself. Finally, since you will try the shot again, i would suggest to find yourself a very close foreground and try the combination wide-angle, hyperfocal, long exposure. Wish you luck, and (since the image is going very well) again congrats on this one. regards. g. Link to comment
