p.1 #1 · p.1 #1 · Can you de-fish 15/2.8 images with DPP?


If not, is there and easy-to-use free SW that does that? I am not much into other SW. I tried several in the past but always came back to DPP. BTW, it will be mounted on a crop body so most of the fishiness is already cropped away. Also. I don't have the 15/2.8 just yet. It's a thought for the future.

TIA.

Happy shooting,
Yakim.

Someone else will have to answer about DPP.

For an alternate solution, panorama stitching software like (free, open source) Hugin also works pretty well for de-fishing. Since the stitcher needs to carefully measure and remap lens distortion for panoramas, you can also save the (very precise) lens distortion correction data determined from a stitch and apply it to single pictures (plus, if you want, vignetting correction). This also makes it easy to straighten perspective distortion in the same workflow.

What's that ? A Nikon version of DPP ?
You probably took a wrong turn at the Nikon - Canon gear forum intersection ?
And this is Canon gear forum.....just in case you might have not noticed.

Look at the software facts page, even their about page, seems last time anything was updated was 2008, even their copyright says 2008...are they still in business, what version of photoshop does the plug-in work with...they list canon dslr's up to the 40d/5d as supported...just check before you buy

DXO Optics Pro does this, but it's not free...

Why? I don't follow the logic:

If you don't have the 15 mm lens, then you must have others that don't require this. Why not use them?

Rendering a fish eye image to "normal" involves a stretching process (pixels have to be pulled apart which reduces resolution). Where the image is shrunk, you will lose image at the edges.

I guess no DPP, right? About the plugin, I do have CS5 but I can't say I like using it.

Glen, I know about that but as I said, on a crop camera most of the distortion is already gone away. My logic is to find a small and light wide lens, preferably with AF, to match a future SL1 + 40/2.8 set. I have used the 15/2.8 in the past on 7D for landscape pics and liked it a lot with no de-fishing needed. Thing is, when you have straight lines near the edges (e.g. in the city), they bend.


Happy shooting,
Yakim.

Never thought about it but I checked and it's roughly the same. But it doesn't matter. I wondered about a SW.

Happy shooting,
Yakim.

Ok it was just a thought .
Thinking being that maybe a lens solution would give better results than de fishing .

Anyway Yakim I hope you find a solution

Yakim:

Like Ian, I'd look for a lens solution, de-fishing being a compromised solution, and IQ suffers. Unfortunately, photography is full of compromises.

I occasionally use DPP just to see how the colours compare, but what DPP needs is more tools like PS or LR and a better interface (specifically a de-fish tool). I'm not familiar with any other SW.

Sorry Brain () sometimes my iphone thinks it knows better than me when I'm typing

Should read "how fishy is the tokina fish zoom at the long end?"

But then I bet most people knew what was meant anyway
