comment Unusual ideas for a 10 yr old taking photos on theme of 'Cold'?
Hi and welcome to photography stackexchange, unfortunately questions that provoke a discussion rather than being something with a definite answer are a poor fit for stackexchange and so are likely to be closed.

comment Nikkor 70-200 2.8 VRII - Does Autofocus <5m really work?
That's handy to know as on the 80-200 f/2.8D limit switch locks focus to either side of the limit depending on where the focus was before you flicked the switch. I'd have expected newer lenses to be the same...

revised Should I store unedited/raw, edited, or watermarked images while backing up on DVD/CD?
Reworked to include feedback from comments.

comment Should I store unedited/raw, edited, or watermarked images while backing up on DVD/CD?
@RomeoNinov - Clearly you didn't read my answer. To back up any reasonable volume of data to optical media so that it is reliably stored and retrievable is a Sisyphean task even if the other issues like dye-rot & scratches didn't make the idea of optical media unreliable.

comment Should I store unedited/raw, edited, or watermarked images while backing up on DVD/CD?
Thanks for the hat-tip. I left the 'how to do backups' part out since it's covered extensively elsewhere like superuser. The main thing I was trying to get across was not how to do backups to a harddisk, but that doing backups to optical media is a Really Bad Idea(tm).

I'm confident that PSD will remain plenty well persevered enough for the foreseeable, same for the raw file formats.

Good answer. I'd prefer the editor's format over TIFF/JPEG - for example PSD since the intent is to store the changes in a way that can be edited.

comment What is the advantage of using L*a*b in Photoshop?
@CountIblis this question is about Lab, if you want to know the difference between XYZ and Lab then that would be a good question to ask.

comment Utilities for comparing different JPEG compression engines?
PNG doesn't have a lossy option but IIRC you can adjust how aggressive the compression algorithm is on some implementations.

comment Does simply opening and closing a JPEG file decrease image quality?
@supercat - block substitution is only possible for certain jpeg encoding schemes. But the selective quality (as in some areas only) option could make for some interesting space savings without major image degradation on the web.

comment JPEG image problem
Hex is a common way to display binary values at the byte level within a file, all files can be displayed and edited using a 'hex editor'.

comment Why use JPEG instead of RAW?
Quite a lot of the points look like reasons to buy bodies with an appropriate megapixel output more than arguments for JPEG. Any complaints about the raw output size from a D800 is akin to a Zonda owner complaining about the cost of fuel, tyres, parts and servicing.

comment How often should memory cards be formatted?
Upvoted for manufacturer references, although as matt points out, it's likely to be fuelled by laziness on their part rather than for any genuine attempt at best-practice.

comment Why are lens apertures usually 1.4, 1.8, 2.8, 4…?
Do you mean powers of √2 instead of multiples?
