Vlog: Long Exposure Photography

[SBha30]

What were your ISO and aperture settings?

[lcc0612]

@SBha30

Towards the end of the night, my ISO was at 200 (the lowest) and aperture at f/22 (the smallest aperture).

This allows me to drag out my shutter speed to 30s (the max)

Hi, It kinda bugged me how a sped up video can be called timelapse? are you sure?

[lcc0612]

@laf979

Hello, sorry for not getting back to you earlier. I never received a notification for your comment.

As far as I understand, a timelapse is any video that involves showing a passage of time, within a shorter time frame.

I guess my timelapse video pushes the definition somewhat, because it's five minutes compressed to 30 seconds.

But in other cases of say, 2 hours of video compressed to 1 minute, I'm sure it fits the definition nicely.

what is exposure bias? im going out tonight to shoot some highways btw! should be fun

[lcc0612]

@Dennisieo

Exposure bias basically "nudges" the acceptable brightness up or down slightly.

If you take a picture on full-auto (ie. The camera makes the decision), and you realise it's too bright, you can reduce the eV to -1 and see if you get a better picture.

Thanks, I will learn from these mistakes and do better next time.

thanks for your input. Next time I take some more and upload them to flickr :)

@maltijien

Cheers! I'll be glad to see your works anytime =)

[maltijien]

Thanks, I dont know about the shakes? unless the bridge was shaking lol;) I had the camera on a tripod and had mirror lock enabled, I think it was the focus as I wasent sure were to focus and in one shot i forgot all about it hahaha.

Any hints regarding focus?

thanks

[maltijien]

update- I also used a wireless remote to trigger the shutter ;)

[lcc0612]

@maltijien

Hmm, I don't think your DSLR is light enough to be shaken by wind either. Maybe I'm wrong, and those weren't shakes at all!

I don't think focus will change on the fly while the exposure is happening, but to be on the safe side, maybe try a "single" focus (ie non-continuous, which means the autofocus will kick in once, and the focal point is locked until the shutter is released)

[maltijien]

@lcc0612 I left focus on manual.I wasent sure were to focus. I think i focused at infinity and pulled back a touch.the other shot with the litted sign on the left was not focused.

[lcc0612]

@maltijien

I'm sure infinity and back a little should be perfectly fine!

The pic you mentioned isn't that badly out of focus, I'd say it's kinda good, actually.

[maltijien]

is your dslr full frame sensor or APS-C? Actually what dslr have you got?

I have a canon 40d with a EFS 17 - 55 IS USM lense. so in reality the f/l for me is 27mm at its widest. :)

[lcc0612]

@maltijien

Hi, I have a Nikon D100 (yep, pretty old model!), which sports an APS-C sensor. (Nikon calls it the DX though) - So it's 1.5x everything.

[maltijien]

@lcc0612 ok cool. Im giving this a try. so wel see what results I get ;)

[lcc0612]

@maltijien

Awesome! Hope to hear from you again and see the results!

[maltijien]

@lcc0612 hey I uploaded them to flickr. here;s the link. flickr dot com/photos/joe190_0/

They turned out ok but I did some heavy editing to them adding some effects. hope you like :))

[lcc0612]

@maltijien

Looks pretty good! I can see some shakes though, which is unfortunate, but all in all I think the effect turned out well!

[maltijien]

inspiring. what focal length lens did you use?

[lcc0612]

@maltijien

Hi, thanks for your comment!

I have two lenses, and I switched between the two throughout the session.

My kit lens is 18~70, and I have a wide angle that's 12~24.

[sondeleb]

great vid man, subbed

[lcc0612]

@sondeleb

Thanks a lot! Glad I could be of help =)

[MARSOC754]

Hey thank you!! This was really helpful!

[lcc0612]

@MARSOC754

Cheers! Glad I could be a help =)

[crazycarper14]

this is brilliant!! Im looking at getting a dslr to do this sort of photography so this is really helpful!! A quick question, how did you create the video? that was really cool!!

[lcc0612]

@crazycarper14

Hello! Thanks for you nice comment!

I filmed this video with the Creative Vado HD 3rd Generation which was my usual camcorder. Because my DSLR is old, it doesn't have video recording capability, otherwise, that works too!

[crazycarper14]

@lcc0612

Ah sorry i meant how you created the video clip at the end with the long shutter speed :D

[lcc0612]

@crazycarper14

Oh that one! That was actually a sped up timelapse clip. I didn't just speed it up but I also enabled frame blending so basically all the in-between frames that should've been discarded in the speedup were instead faded into the remaining frame... In other words, I cheated =D

[spenceisadork]

Thanks bro, I'm doing some work liek this in CG and your video is a valuable reference.

[lcc0612]

@spenceisadork

Thanks a lot for your kind words! I'm glad I could be a help!

[marcusqwerty]

Instead of the timer, you can use a shutter release. By the way, what kind of camera are you using?

[lcc0612]

@marcusqwerty

True, that! I should've mentioned it xD I didn't have a shutter release myself so I totally forgot to mention it!

I'm using a second-hand Nikon D100. Not the newest toy on the market, but we don't have a lot of spare cash so I'm glad my uncle (a professional photographer) was nice enough to give his old camera to me!

[MaximSachs]

nice
