huydo1409 Posted January 22 Share #1 Posted January 22 Advertisement (gone after registration) Hello, sorry if my English is not good. I just bought a Leica m6 classic and I love it. The maximum shutter speed is 1/1000, however there are many times when I shoot the Kodak Portra 400 outdoors and the speed of 1/1000 causes me to have a small aperture. I want to set the aperture to f2.8 or f3.2 photos are overexposed on the light meter. So what should I do? can i use nd filter? Because as I understand it, the Leica m6 classic does not measure light through the lens, so if there are many nd filters, how should I use them? I have a Nikon fm2n, the maximum shutter speed is 1/2000, it's easier for me to choose the aperture when shooting outdoors in the sun. but I also love the Leica m6 Link to post Share on other sites More sharing options...

jgeenen Posted January 22 Share #4 Posted January 22 ND filters are perfect for your use case. Depending on the brand, the density is either named in density units (0.3 is one f-stop) or factors (2x is one f-stop, 4x is two f-Stops etc.). I have a three-stop ND for that purpose (ND 0.9 or ND 8x) that should be ok for most scenarios. The M6 measures through the lens, so exposure metering will include the filter density automatically , similar to your FM2n. When using an external meter, just subtract the number of f-stops according to the filter density. 1 Link to post Share on other sites More sharing options...

No adjustment of ISO required. Sure, the shutter speed will change (or the aperture) but this will be displayed by the internal metering system of the M6 automatically. Just put the filter on the front and continue metering and shooting 1 Link to post Share on other sites More sharing options...

Tùy thuộc vào thương hiệu, mật độ được đặt tên theo đơn vị mật độ (0,3 là một f-stop) hoặc các yếu tố (2x là một f-stop, 4x là hai f-Stop, v.v.). Tôi có một ND ba điểm dừng cho mục đích đó (ND 0.9 hoặc ND 8x) sẽ ổn cho hầu hết các tình huống. M6 đo thông qua ống kính, vì vậy đo phơi sáng sẽ tự động bao gồm mật độ bộ lọc, tương tự như FM2n của bạn. Khi sử dụng đồng hồ đo bên ngoài, chỉ cần trừ đi số f-stop theo mật độ bộ lọc. Thank you, that means I installed the nd filter. If I measure light with m6, I just rely on the light meter as usual. And if I use external metering, I will need to subtract the corresponding f-stop number? Link to post Share on other sites More sharing options...

Chắc chắn, tốc độ màn trập sẽ thay đổi (hoặc khẩu độ) nhưng điều này sẽ tự động được hiển thị bởi hệ thống đo sáng bên trong của M6. Chỉ cần đặt bộ lọc ở phía trước và tiếp tục đo sáng và chụp Thank you, so I installed the nd filter and used the m6 meter as usual.

Do you have any suggestions about nd filter? I use Voigtlander 35 f2 ultron, filter size is 39mm, I can't find any filter with this size. Link to post Share on other sites More sharing options...
jgeenen Posted January 22 Share #11 Posted January 22 39mm is a less common size nowadays, but all mayor brands list them. I usually use B+W filters from Germany but I have a very convenient and flexible set of three filters 8x, 64x, 1000x from Haida, which I bought at Amazon. I haven’t had any issues with that set (but I don‘t do scientific tests) and the combo is very flexible - the 8x gives three stops, the 64x six stops and the 1000x ten stops which is is perfect for long exposures during daylight. filters with cheap glass/coating could exhibit color shifts (especially the darker 1000x can be an issue here), so it is a good idea to stick to mayor brands with reputation. eBay might be a good source as well, ND filters are typically not used that often. 1 Link to post Share on other sites More sharing options...

Tôi thường sử dụng bộ lọc B+W từ Đức nhưng tôi có một bộ ba bộ lọc rất tiện lợi và linh hoạt gồm 8x, 64x, 1000x từ Haida, mà tôi đã mua trên Amazon. Tôi chưa gặp vấn đề gì với bộ đó (nhưng tôi không làm các thử nghiệm khoa học) và bộ kết hợp này rất linh hoạt - 8x cung cấp ba điểm dừng, 64x sáu điểm dừng và 1000x mười điểm dừng, hoàn hảo cho việc phơi sáng lâu trong điều kiện ban ngày. các bộ lọc có lớp phủ/lớp kính rẻ tiền có thể bị đổi màu (đặc biệt là bộ lọc 1000x tối hơn có thể là vấn đề ở đây), vì vậy, tốt nhất là nên sử dụng các thương hiệu uy tín. eBay cũng có thể là một nguồn tốt, vì bộ lọc ND thường không được sử dụng thường xuyên. Thank you, I'm in Vietnam, Haida is also available in Vietnam but only the smallest size is 49mm, b+w is also hard to find 39mm. I guess I need to look more closely Link to post Share on other sites More sharing options...

Sergius Posted January 23 Share #15 Posted January 23 Why don’t use a Portra 160 ? Best results and less expensive than ND filters. 2 Link to post Share on other sites More sharing options...
BradS Posted February 1 Share #16 Posted February 1 The 1/1000 top speed has been plenty good enough for over 70 years. The sane thing to do is use a film with a lower ISO rating when photography out doors in daylight. 1 Link to post Share on other sites More sharing options...

For decades my favorite film was Kodachrome II with an "ASA" speed of 25. 1/1000 was rather useless with that, and several of my cameras didn't go that fast. 1 Link to post Share on other sites More sharing options...

Mute-on Posted February 2 Share #19 Posted February 2 (edited) Portra 160 does not render the same as Portra 400, it is less saturated and generates more pastel colours. To retain Portra 400 colours and avoid having to stop down excessively, an ND filter is the only option. Personally, I would shoot Portra 400 at 200 (begrudgingly, as I think it’s better at 400) and stop down to 5.6-8.0 as required. However I don’t care about shallow DOF. Many other do.

_leicaguru Posted February 2 Share #20 Posted February 2 2 hours ago, Mute-on said: stop down to 5.6-8.0 Thing is he also wants to shoot with blurry backgrounds apparently. First a variable ND filter is a must, but if that doesn't work then he needs to shoot slower film and whatever colors he needs to change in post he can change. The obvious answer is to stop down, but ah well. Link to post Share on other sites More sharing options...
