Persepctive distortion with a wide angle lens

[Colin Southern]

With one or two noted exceptions - good job!

The ones I'm thinking of are more buildings where they're more 3 dimensional, and the shooter has gone in close (and also at a reasonably low elevation) and then forced the edges vertical ... although it's probably "correct", we're so used to seeing some degree of convergence that something just doesn't look right in those types of shots.

Hey that image was not mine, but from a recent 17mm TS-E owner.

I agree with you. In professional arquitecture photography it's very rare to go lower than 24mm (FF), the widest focal length generally accepted in this field. For indoor shooting, although not trespassing the 24mm limit is again desirable, sometimes it has to be done but very carefully.

Someone said once something with which I completly agree about arquitecture photography and the wide angle lenses: "If I look at a photograph and the first thing I see is the lens, then this lens is not working for that image".

I plan to by the 24mm TS-E II and try indoor shooting to educate my abilities in cropping and composition. Using 24mm to represent narrow spaces is far from an easy task, but when achieved, the 24mm angle of view is a guarantee of natural and pleasant perspectives.

Regards.

I was thinking of getting either a TS-E 17mm or 25mm II to have a bit of fun with -- still waiting for the dealer to call me back to say they're in stock!

I am just waiting to get TS-E 24mm II, but not in stock anywhere yet, i hope to get it before October as i will travel.

back to the question regarding DxO, I use it a as part of my PP process and it's been really good. You can adjust a lot of things by yourself and also do a lot of PP automatically.

what I don is, importing the pictures as RAW file to an external HD, then open them using DxO and process them.
After that I get TIFF files, which I import into Aperture in order to:
1. pre-sharpening
2. noise reduction
3. apply a filter o boost a specific colour or just crop
4. output sharpening

The only downside with DxO is that your camera-lens combination must be already profiled by them, otherwise, if your camera is profiled but your lens isn't, then you have to make all he adjustments by yourself.

Hope it helps.

Out of interest Daniel, how easy is it to tell DxO to only make the corrections that you want, and then to leave everything else alone (eg correct lens distortions and CA, but don't touch exposure or vignetting?)

[Daniel Salazar]

I'll try it tonight and post it, however I think is easy because you can create your own correction set, in which you can choose colour rendering, yes I can select to apply the colour of a eg Nikon D3x to all my pictures even I don't own one, etc.

I'll try it tonight and post it.

Thanks Daniel

yes I checked and you can select or deselect and also adjust exposure compensation, vignetting, sharpness, lightning, tone curves, chromatic aberration, etc. It means, you can make your own changes, set the corrections as you want.

As mentioned before, the only problem is that it adds another step to your workflow.
