Reprocess your old images?

[EzyStyles (Eric)]

Just want to see whether you would reprocess your old images once youve gain more and more experience from processing? im not talking about images taken a few weeks/months ago, im taking about last year or two?

I'm tiffing whether i should but at the sametime, i also want to see how and where i have improved from the past.

cheers guys, just want to see your opinion.

Sometimes I do go back through old planetary data and try and reprocess it. Sometimes I get a better result, sometimes not. Depends on the quality of the original data.

For my DSLR images, I won't bother because I made too many mistakes early on (not enough exposure, not enough subs, no flats, etc). I'd prefer to spend time capturing better data first.

Hi Eric,
for my part, within the limitations of the quality of the captured data, as I learn better processing techniques, I often try and go back and see if I can get better outcomes from the data collected earlier. My problem is , as Mike says, the poor quality of the data I collected early on which doesn't leave me much to work with. So I usually just leave them alone, especially the very early ones.

I votes "I don't care" but on some images that I know were good data when captured, I'll go back and reprocess when I learn a new technique to see what I can get out of it...

On a slightly different but similar note, has anyone every gone back to get ALL their good data from an object (ie the hundred or so subs that everyone must have of M42), and stacked them all together?

Is this even feasible with matching of flats/darks etc?

Even better, we get everyone on IIS to provide final reduced stacks of each colour (un-stretched/un-processed), and then do a mega-stack? I don't know if I want to be the bunny who has to try to get the image scales matched and processed though!

Now that I have been shown how to actually process images at all, i do go back and try the skills i have learned and see some great improvements.

However i seem to have two lots of back dated images, the first lot is of very short exposures before i learned auto guiding and the second obviously after i have gained that experience.

I reckon it is a great idea and one can see what skills have improved over the past twelve months or so,

I like to compare what I did then with what I'm doing now so I don't reprocess my old images.

However I sometimes combine old and new data to see what the new image will come out like but I still keep the old image original.

The few i have taken so far, i have revisited a number of times.

1. To implement comments/guidance by others.
2. Try processing i have subsequently learned, from guides, books etc.
3. To understand the process better and come up with a process flow that i can use time and again.

The current rainy weather limits the ability to collect more data, perhaps if this was not the case i might not revisit. The Cloudy nights provide time to improve.
