Snow relects the sky so can look too blue. 81A filter or set AWB to Cloudy.

All that white affects metering so shots may be too dark. + exposure compensation.

Keep batteries warm.

Have a great time!

Steady on, 'nowt wrong with being oop North!

Don't forget even the good Doctor declared, "Every planet has a North..."

I'm aware that there is a new new model of the Lubitel that has just been released and it is more expensive, but just offhand I didn't take much notice so can't remember the price.

You said it.

Lens distortion is a totally different subject to converging verticals, which is an optical effect that just exists.

Lens distortion of the barrel or pincushion variety is commonly found in wide angle and telephoto lenses respectively but is a defect of the lens.

Converging verticals could I suppose be called a defect of the subject, or maybe of Physics! Of course, it isn't a defect at all.

Selectibe sharpening can be applied by making a Selection in Photoshop and applying the sharpening within the selection. You can feather the edges of the selection to avoid sharp transitions if required.

shim, what distortion are you referring to?

Ah, the Lubitel, just about the cheapest Twin Lens Reflex ever made. There are various versions, but they all amount to the same thing - cheap and cheerful.

Put in a 120 film and you too can get moderately sharp images, but you'll also need a fair amount of photographic esxpertise to get the best out of this camera. No automation or help of any kind!

A TIFF file is lossless, so it certainly contains all the information to reassemble the image.

Converging verticals are correct.

Think of it like this. If you looked at a train track receding off into the distance it would converge to a point. We expect that, it's a fact. And we don't try to correct it! These are converging horizontals and our eyes and minds accept this as normal.

Now look upwards. Straight lines in buildings do the same thing - they converge to a point in the distance. We expect them to and it looks right. Unfortunately when we look at a photograph our minds rebel and we want then convergence "corrected" - in fact try correcting converging horizontals and see how weird it looks.

How to "correct" converging verticals is to use a Shift Lens, or use Photoshop. Transform>Skew or Transform>Distort will both do the job. Just pull the image into the shape you want and then recrop to eliminate the bits of the image you can no longer see (but which are stiil there using up memory). Obviously there's a limit to how far you can go with this.

The final way is to keep the camera back vertical, use an ultra wide lens and crop out the excess foreground.
