Verticals, Barrel Distortion, and pin cushion correction needed...

view profile

jk0305aa says:

I have been visiting this site for 3 months now and have gathered volumes of helpful information from all of you. So let me start out by saying THANK YOU! I am a Real Estate Photographer employed by one of the National Companies. I can not stay at this job any longer since I am trading too much time and talent for too little money!

I need to get up to speed with the rest of you who have become my "mentors". I am using Lightroom for post production. I need a stand alone product for converging verticals, barrel distortion, and pin cushion
correction. I have tried PTLens, and ShiftN. Do you recommend these products or is there something else I should explore?

In the next 30 days I hope to be on the streets kicking around for work like the rest of you probably had to do in the beginning. I have a dozen or so questions but I don't want to dump it all on you at one time. I'll ask one question per week. Any and all help is appreciated. Aaron and Scott, you have set the bench mark for me.

JK

Buy DxO. Period. They just released a new version that allows you to open photos from within Lightroom, correct them in DxO and then go back to Lightroom for the rest.

Thanks again for the advice on DXO.... I did my home work and I now which version to get. Looks like DXO wants some market share with Lightroom users.

Hi aaron2005,

When you make the DxO corrections, are you still working with non-destructive sidecar edits to the original RAW file?

Or do you have to convert to a TIFF?

I've watched the DxO video a few times. I'm using PS for most of the work LR can't handle. Has anyone switched from PS to DxO? Is it worth it to make the switch? I like the LR integration, but not completely sold on the other features.

Question re: DxO - to achieve the distortion corrections they offer, *must* one use the camera & lens combination? I have a Tokina 12-24mm f/4 lens that is not listed w/ my camera (d200). To get distortion correction w/ this software, am I forced to buy a new lens?

Are there any other solutions that are not so camera / lens combination dependent? Or is this simply *the* best? The features on the website certainly look impressive for the price...

I'm an old windows user and I've recently purchased a MacBook Pro and since I have CS3 for my windows machine and don't want to purchase another copy for my Macbook I've been seriously looking at purchasing DxO for my Macbook Just for lens and perspective correction.

Lens and perspecive correction are a small part of DxO. Most all of the non-lens correction stuff in DxO i can do with lightroom. I use more than one camera/lens for interiors and DxO would only work for my 1Ds/16mm. Also, in using the demo I find that DxO has difficulty in reading/displaying some files (I haven't researched this problem).

My assessment at this point is that DxO is too expensive an alternative for just doing perspective and lens distortion because it has so much overlap with Lightroom. I think I'm going to get a copy of LensDoc which is almost 1/3 the price of DxO, has no overlap with Lightroom and is excellent at just fixing lens and perspective distortion for any camera/lens combination.

Lohrman, thanks for the reply. I am relatively new to digital, having just picked up my d200 last Christmas, and have just barely cracked open CS2. However, I am trying to prioritize and assess my software and hardware purchases appropriately...have CS2 for WIN, but would like to go MacBook Pro when I make my next large investment. The world of plug-ins, raw conversion tools, and overall set of alternatives and complements to PS is pretty overwhelming for a relative noob in this area....and I thought after 13 years of photographic experience I would not feel like a noob ever again...d'oh.

Further to Scott's blog post
I came across this useful comparison of distortion correction for three popular WA lenses:

You don't need software to get perspective correct unless you have an unusual shooting situation (ie shooting a raised lot, very tall house, etc)

Perspective (verticals converging/diverging) should be mitigated in camera through proper technique, what minor lens distortion that's left over can be quickly zapped in ptlens for $25.


Remember this-if you pay attention to keeping your camera level when you shoot you can easily get away with just using lightroom and ptlens. That would give you an integrated product solution without dropping big $ and leave some money left over to acquire elements or cs4 if you really need the skew tool.

Software is not an excuse for poor technique- it's a better result and takes less time to get everything right in camera when possible.

Photoshop Elements has great tools for correcting verticals, barrel distortion and pin-cushioning. Use the skew tool for converging verticals and the "correct camera distortion" tool for barrel and pin-cushioning distortion.

Kerry. Whilst I accept your sentiment, I found a different method works for me.
A long time ago I used to shoot with a bubble level on the hot shoe and a three way head, [having to remove the bubble level to put my commander light back on for each shot]. Taking time to get the shot absolutely right in camera. But I found that most images still needed a slight tweek to perfect them. So rather than spend 1 min levelling plus 30sec in post, I decided to shoot quickly with a ball head, get very close to right in camera and tweek in post. Saves me 1min per shot, or about an hour per shoot. Same amount of time in post. I don't shoot sloppily, just quickly, I'm usually only a fraction of a degree out.

KerryPuckett says:

Marcus,

I agree with you. I shoot with a ball head and I can get everything leveled out within a degree or two by eye in about 15-30 seconds. After a slight rotation in LR and a trip through PtLens the result is more than good enough for PFRE at this point (only a discerning photographer would notice). Often I'll pop into CS2 and use the skew tool to correct that slight distortion that remains, but I'm only shooting 15 images or less so it's not a big deal for me.

I was just suggesting that method so the OP could save $ while starting out.

Ahh, I see, I resurrected this post from '07, rather than start a new thread, as some interesting info came up as a result of the discussion going on at Scott's blog.

Well, that changes things immensely then- can't believe I missed that part....

PtLens does a great job though- especially considering the price. The fact it corrects the CA simultaneously is a big plus over photoshop's correction filter
