As I understand it, that is what the resampling algorithms take care of on your behalf - so that there is no problem for you to select any smaller size at all.

Thus, the answer to your question is that, using the above method, there is no 'better or worse' in this - it's entirely your choice, and no penalty attached for using 'odd' sizes.

By way of example, if you took an image, did an 'odd-shaped' crop of it, then resized the crop, you would almost certainly end up with odd numbers on either or both axes.

That happens regularly - and I can't tell the difference solely on that account.

Happy resampling!

Have you a control image taken of that subject without the TC per chance?

If you were to use a free bit of software such as IrfanView (brilliant IMO), then it will handle the re-size / resample for you, as well as offering you choices for retaining the proportion of crops (or not), various resampling algorithms, dpi adjustment, 'resharpen after resize' option, etc. Pretty impressive for zero dollars.

Like the sharpness and the light!

So they don't cotton on until you nudge them?

Nice work Tim

Thanks for responding Ian, Fr Ted and Paul.

Some weather proofed bodies and lenses (even at kit level)?

Dave,

You've already got some good advice here. I wonder though what you actually intend to do, when you say 'predominantly indoor pics of the kids'?

Two parts to that - what hangs off the word 'predominantly'? What else will you be doing with it, and how does that affect your choice/s?

Secondly, pics of the kids: Are you looking at action shots of a number of kids? (I reckon you probably are). But - perhaps you are doing portraits of individual kids? These two choices of 'kids pics' are important for you. If it is about groups of kids in action, flexibility and a wide angle are more important. That may suggest a closer look at a short zoom.

If it is mainly kids portraits, then a portrait-length prime (eg a fast 50 or 70mm) might be better for you.

But the 'other' uses you are contemplating may have a bearing on your choice too. Perhaps a zoom to start with, and then do a check of all your images after a time to see what focal lengths you're actually using?

The you could make some further evidence-based choices on additional lenses (or not )

Cheers Alun.

G'Day and welcome Bill.
