Animation of HA action around 2602

[Iainp]

Half an hour of Smash and Grab this morning with low sun through thin cloud. Seeing not too bad considering though.  Nice action going on there anyway (57 frames)

Nicely done.

Another nice animation Iain, half an hour eh they're spoiling you.

Great animation Iain.

Very nice Iain. Lovely activity going on. The only thing is the uneven brightness between frames. Is there any way to deal with that?

Thanks all.

Yes it's a pain isn't it?  There's a GIMP plugin which is supposed to normalise all frames but it doesn't seem to make much difference.  I've come to the conclusion that I shouldn't do animations when there's thin cloud around like this, but like an addict I keep going back on the promises!

Iain. Why not deal with each frame individually? Photoshop gives the average brightness reading for each frame. But if you don't have that software, why not choose a master frame and do side by side adjustments of brightness for all the other frames to at least approach the master and therefore achieve uniformity?

Hi Charles, yes, that helps but the problem I have is that the thin cloud affect the contrast, so some frames are more of a uniform grey and the others cover more of the tonal range from black to white so even after normalising the frames they still look quite different. Also it does take a lot of time and effort. I'm impressed you have the patience for individual frame adjustment!

Hi Iain. I can totally relate with that sentiment. I actually attempt to adjust the contrast individually as well. The good thing about animations is that the differences are less apparent as the frames flash through. But it does take a lot of work. I will only do it if I think it is really worth such an effort. that's a good 3-4 hour worth of post-processing right there.
