This topic to share your tips, your tricks to take awesome photos as yours ! ;)

 

Thank you in advance!

For the lucky ones who own an iPhone an appli "how to calculate your exposure time with a neutral density filter"

 

I find it very useful, well, i'm a beginner, i don't know what the "experts" will think of it ;-)

It is free.

Thanks a lot for this apply! I think it will be interesting for me!

Little secret.

 

For long exposure photography in a tripod, is better! :-P

Joking aside (especially that is not true if we consider the 1/200sec like long exposure , see other topic)

 

You can make excellent long poses, just after the sunset time. I'm not an early bird, but I guess it works well.

 

At that time the day you can take pictures without filters which is a big advantage, you used all the quality of your couple, camera / lens. Another advantage is you do not have to buy a filter and you do not need to know counted, which can help to make his first long exposure, with a great quality and without investing anything!

 

So go to it!

Hi all,

 

When i use a LEE BIG stopper and i use 60-120 seconds exposure, i have always an incredible noise in the photo.

 

I'm using a 5d mkII with lowest iso 50-100..

 

Who have a problem solution?

 

thanks a lot

Piero

Hi !

 

on your you must have a option in the menu : "long exposure noise reduction" or equivalent.

another solution will be to make a "Dark" and developed with a software for astro-photography like "IRIS"

Thanks Victorien..

What do you mean with "make a Dark"? Do you mean a shoot with the same exposure time but with a lens cap mounted?

exactly Piero, you make a shoot with the same exposure time with a lens cap mounted.

 

this photo allows to mapping thermic noise.

 

and with free software like IRIS , you can to disappear the thermic noise on le real photo.

wonderful.. a little bit boring but functionally i hope!

i'll try it as soon i can!

 

thanks a lot,

Piero

damn, i'm using mac.. Iris is for windows user only.. other apps?

for sure it's functionally !

 

but your 5D MKII must have "Long exposure noise reduction " (LENR) . this function make a "dark" and process automatically.

 

"Lynkeos" is a free software for astrophotography on Mac , but i never used

 

For really punchy skies, use a polarizing filter along with an ND filter. The clouds will get whispy and bright white, and the sky behind it will be almost black. Especially good looking when converting to black and white.

 

Hello Piero

 

Your sensor is probably overheating, which is a very common problem with long exposure.

Thanks martin for your comment, I Never use the ND filter without Polarised, but it's true that it is good to remember it ! ;-)

 

 

thanks, good comment!

One other solution against the noise is cooling the camera. Especially while shooting photos with night-sky (stars, clouds etc.) in the background it is really helpful to wait for a cold night. I await the winter in Germany with anticipation, because cold temperature means a cold camera, and for me it emerged that this is really helpful for using longer exposure or higher ISO-amounts. You just have to be very careful because of condensation and material stretching when your camera goes back to a warm place.

interesting trick, thank you Jan T.

 

I've never seen any difference in terms of the weather, but it would be interesting to be examined to see how significant it is.
