Sử dụng ND filter hay là Mean Stack Mode? Lúc gần đây có vài người bạn hỏi về chuyện chụp ảnh “slow motion”, hỏi tui ND/Polarizer filter loại nào, kinh nghiệm chụp ra sao, v.v.. Thì câu trả lời thật tình là tui không còn dùng filter cho máy ảnh đã lâu lắm rồi, kể cả UV filter, hay nói cách khác là trước ống kính chỉ có cái nắp nhựa bảo vệ lăng kính khi không chụp thôi. Bạn tui hỏi tại sao không dùng filter nửa, thì câu trả lời là lợi và bất lợi như hai vế dưới đây: DN filter Mean Photoshop Stack Mode Lợi Thế Bất Lợi Lợi Thế Bất Lợi Chụp xong thấy ngay kết quả trong máy chụp. 1/ Tốn thời gian lúc chụp. 2/ Ánh sáng mạnh quá sẽ không thể mờ như ý, nếu gắn ND đậm hơn 9X thì hình sẽ có nhiều màu đỏ. 3/ Ảnh sẽ kém nét so sự tán quang khi ánh sáng đi qua filter. 4 không thể chọn một vùng trong ảnh rõ như ý muốn. 1/ Không tốn tiền mua filter. 2/ Hình không bị “noise” do phơi sáng quá lâu. 3/ Có […]
Mesa Arch Windows of Heaven The Mesa Arch is located in the Canyonlands National Park. The closest town is Moab, Utah. Follow Google map Below is a full view nearly fish eyes view of the arch, right at the edge of the mesa, next to a drop of almost a thousand feet straight down, it frames a vast expense of canyons. The Mesa Arch is a very popular destination for tourists and photographers. I have seen that morning 50 tourists and photographers at the arch at sunrise. The arch is only about 25ft. across and there are only about few premium spots. Even I was there 3 hours before sunrise, a group of more than 15 photographers had been there with tripods. Don’t be too worry, the red glow under the arch lasts for about an hour after sunrise, believe me, after sunrise about 30 minutes, you can still get a great shot. I shot this one alone after all people left, 7 shots merged with tripod on the very edge of the cliff. Below is a shot of a view of most people been there, only the arch. But if you use normal lens, some interested angle view could […]
Read English Version False Kiva Khi thiên nhiên và cấu trúc của con người tạo ra gặp nhau trong sự hài hòa Một ảnh tương tự khác nhưng vòng đá được thấy gần trung tâm của bức ảnh, dẫn thị giác đi về phía ngọn núi nhỏ có hình dáng ngọn nến ở xa xa . Dân săn ảnh đến đây thích dùng ống kính góc thật rộng cở như 10mm để gom hết toàn cảnh cửa hốc núi. Riêng ảnh nầy tôi ghép lại với 7 tấm ảnh chụp máy đứng với ống kính 20mm, khi chụp với thiết bị đặc biệt Manfrotto Spherical Head , và mổi tấm ảnh được chụp 5 lần theo kỹ thuật HDR. Tấm ảnh thì công phu và phức tạp, nhưng không ấn tượng lắm vì sự rối ren và lộn xộn của nhiều vòng tròn. False Kiva là gì, và ở đâu? Xin giới thiệu cùng các bạn ảnh đó là một vòng tròn nhân tạo bởi những hòn đá chồng lên nhau mà không rõ nguồn gốc chính xác nó hình thành khi nào. Cái tên False Kiva hiểu theo nghĩa là “nhà nguyện ảo” ai đó đặt ra ngụ ý nói không chắc nó […]

Most people like to take full view of the alcove with extremely wide angle like 10mm, this shot I made a set of a stitch panoramic 7 frames vertically 20mm lens using Manfrotto Spherical Head , each frame contains 5 HDR images.

Additionally, ten online permits for each date are available four months in advance of a planned trip. The number of people allowed into the area is strictly limited.
