Olympus Live Composite Function

[wonglp]

Another Live Comp practice

Comments and criticism are warmly welcome, Thanks for your advice in advance.
I am new to this stuff, so your comments are really helpful for me to understand better.

Thanks

excellent improvements Perhaps just a few comments, the 1st shot, do watch the perspective distortions (keystone), can see the buildings is diverging (lens is pointing downwards), the right corner building is rather distracting. The highlights on esplanade drive if can tone down some highlights might be good.
2nd shot, is this evening like first shot? a little strange not to see flyer moving.
Keep shooting!

I still can't get it right I think. And there was some fisherman who was knocking on the railing that my camera was clamping to, but here goes my attempt at Live Composite -

5s x 100, about 8 mins plus?

There were only 3 trains heading eastwards at those 8 mins and I am clearly frustrated that I don't get my light trails.

Thanks for your valuable comments,
The images are straight from the camera jpg, not PP only resize
1) Perspective distortions -- Not very sure how to remove them. Maybe I try with a tighter crop. Will try to point it more straight as well.
Yes cars and boat are moving at different speed and different lighting. Maybe better to have less than to include distraction

2) Second shot was shot at a different session, you notice lots of details, WongLP

Thanks Spider, will keep shooting.

That's because ur exposure was too long. Go for a lower 5-30 sec exposure for a more distinct light trail. If ur exposure was too long, ur moving subject will disappear.

His base shot was 5sec, I think the sky is a little bright still, the composite works well if the trails are "lighter" than environment. great effort Bernard! If it's just a tad later, should able to see more, including more reflections. Let's shoot there someday

 

[hjbyeo]

8 mins 3 trains ... at 5s that's the longest 3 strokes you can see. You'll need a bit more than the 3 trains to get the light trails on the right hand track at 5secs interval.

It's still pretty bright when I started, but it was a impromptu shooting. Pass by the station and thought to try it. I'll work this out better again the next time round.

Yes, LP, it's 5 seconds base image as indicated on the description. 5s (1 shot) x 100 shots.

Let's all keep trying! ;-)

Yup if the sky is slightly darker the reflection will be more contrasting.

I haven't had time to try this feature yet, but I have a noob question.

The 5s base time is it equivalent to 5s/8min exposure in bulb/time mode?

No noob question for sure But sorry I dun really get your question. 5s base shot image form the exposure time of the next 100shots in live composite. If bulb or time, a 5sec shot is a 5 sec shot, a 8min shot is a 8min shot. Not sure if this answers your questions.

Thank you for your prompt reply.

That means in live composite, all the 100 shots add up will eventually be a 5s exposure for the image, and it's also equivalent to 5s of bulb mode.

Am I right?

 

[spidey89]

From my exif file, eg 5 sec composite will be 5 sec cause whether in camera or photoshop, all exposures are 5 secs, rather than a combination of shutter speeds for that one photo

Ok I get it now. Thanks for the info. [emoji4]

yes it is a 5sec exposure, the effects though is a composite of all the shots, I would think the application of it is the key.
E.g. this shot is a short base time of 2.5sec (with help of ND filter, 6 stops iirc), stacked for 2-3mins in total. However, if I were to do a long exposure for 2-3min single shot, it wouldn't look like that, rather the trails will be very faint. It was interesting to see LC in evening shots like this

Very nice. I guess bulb mode can't achieve this kind of effective at all and a lot of highlights will be blown for such long exposure. Again thanks for the explanation. Cheers!

Welcome and thanks. Not the effects with bulb. As for blown highlights, all depends on ND filter strength tat you use to stretch to 2-3min, since live bulb/time you can see it happening, exposure should be in your control.

Dear teacher WongLP,
Attached is the corrected/Redo assignment for your marking

Comments from other teachers are welcome
I started this shot earlier by 3 min to highlight the number 50, from the result I am not so sure it is a good thing.

Some comments I have, the MBS was chopped off rather abruptly. If you are using lightroom, you can correct the perspective distortions under lens correction. The trails works well, u staying in a hotel? Nothing much else to add really Not teacher just my 2 cents

 

[wonglp]

Sharing a shot that was done during the last sharing session at Clarke quay, the composite included some motions from other friends that evening, I actually forgot to shoot Raw for this shot,as much as I emphasised during sharing
Using EM10+Oly 9-18 @F7.1, 9mm, 2.5s, for about 2min.

 

[hjbyeo]

5s - 100, 2.5s - 25, 2 image stitched, Oly 12-40 @ 12, f8.



Having a blast with this feature!!

Add on to what LP said about perspective distortions, if you're using lightroom 5, there's the auto feature which will try to do it for you automatically, works quite well whenever I used it. Also I found your picture to be rather flat for the latest one, the one later was more contrasty

 

[Cobia]

Thanks Spidey89, yes my bad was to eager to start, should have waited for a better time to take the picture

hjbyeo has a good concept

My latest try with Live Comp

I guess on seeing this wonglp would have guess what I was trying to do but was afraid to put here.
