It's not a technical matter, Smeggypants, it's an aesthetic one. Doing all these things gives different pictorial effects, some of which can be very attractive.

1EV or eben 0.5EV steps, usually seven exposures, processed through Photomatix can give some very powerful results.

This is an example, using a preset called "grunge".

I would expect it to be slow for the first half of the month as it's unlikely we could leap into action and shoot our entry in the first few days.

At least monthly gives us all time and the turnout was very good, which seems to support that.

Smeggypants has posted an HDR image of a type that could not be created with multiple images - a moving subject. In this instance I'm sure the in-camera HDR is an interesting possibility, as is the multiple processing of a single RAW capture. A single JPEG could be used to make an HDR image, but it's a bit iffy as a process.

Part of the success or failure will be whether or not judges set accessible tasks. The more bizarre they are the less likely there will be participation, so keep it simple so we can all have a go!

Thank you matron. The adverts on here are not controlled by PU. I think they are Google Ads, so we get what reflects what we are looking at I suppose.

Quicker isn't always better though. It depends on our own approach and what we are tring to achieve.

Some will batch process images, and I've never seen the logic in that as every shot may need a slightly different adjustment. Some may spend literally days or weeks fine tuning a single image. I certainly don't have the patience for that.

No approach is necessarily wrong, if it's the way to achieve what is visualised.

The winner and comments have now been posted. The response seems to have been a good one, what do you think?

I've dedited out that e-mail address to prevent you being spammed. If you initially communicate by PM it will be much safer.

If I can squeeze a little more crispness out of a print by having a think about this then it's not a waste. I can't afford an A2 (or bigger) printer so buying in is the only option.

I understand the process of resizing and re-sampling, but the tip I had was to perform this in stages. Rather than increasing the size of an image by 100% in one hop, I have it on good authority (untested as yet) that to perform this in a series of smaller steps, results in a superior image.

Admitedly, a 100% increase is only an extra pixel between two others, so hardly a tough ask, but I suppose it might make a difference on a bigger stretch. Anyway a bit of homework will reveal.

This used to be the case, but is no longer necessary. Photoshop or Genuine Fractals will do the job in one step. Not all other programs may do as good a job, but of course it can be tested by trying it out.

The extra pixels needed to maintain 300ppi are creted in Photoshop by resampling the image.

Bicubic is very satisfactory and for greater refinement in more extreme size changes, bicubic smoother to upsize and bicubic sharper to downsize. You might want to downsize for the web and this will keep your image looking sharp.
