Hi all.

Thoughts / opinions on these kind of things... I know that they're cheap so won't be AMAZING but, will they be work $15 and a little bit of fun?

Will they work on a 500D and 18-55mm Canon lens? From what I understand, they simply screw on like a filter and give macro(-ish) shots. Correct?

Alternatively, what about one of these?

Terrible. Get a manual focus 50mm and macro extension tubes/bellows or an enlarging lens and a set of bellows (or make bellows if you're the diy type)

Getting a press, lol.

What I currently do, to get them flatter before pressing them, is leaving them in box emulsion to emulsion so they flattened over time from weight. But you'll never get it completely flat unless you use a press.

Thanks, but isn't a new lens going to be MUCH more than £10?

+1 for using enlarging lenses.

i dont do macro work but pretty much every good macro lens i know of is prime which means that more than likely if you are doing macro work you probably are wanting a prime. therefore it has been suggested to you to look into a 50 1.8 which is canons cheapest and very quality for its price prime lens. i also suggest looking for a used one to save money. noone is going to tell you that the 50 1.8 is better quality than the 18-55 but i will tell you that you will be very amazed by the quality it has to offer.

what foothead has suggested is a very good idea if you want to get into and try out macro photography and if you find that you really like it then invest in a macro lens

I use some M42 bellows with a M39 to M42 adapter inside of a M42 to PK adapter with a Rodagon 50mm enlarging lens which gives pleasing results and didn't cost much.

i remember doing this to straighten something but dont remember what.....

I like this idea. I was thinking about maybe trying to put the paper in the oven also, but our oven is filthy and I don't want to get food residue on the prints.

I'm looking into getting a press, they're just kinda hard to find. There's a couple on ebay, but both are like 14x17 max, and I'd rather have the possibility of doing 16x20 in the future.

Doesn't have to be new. Actually an old lens would be better for this. Go on ebay and start looking for an old enlarging lens somewhere around 50mm. The best ones are going to be the componons, rodagons, and el-nikkors, though I've seen some from other brands that were still pretty decent. The other option that I mentioned was an old ~50mm prime lens. I've gotten these for $1 at garage sales before, and they're almost always good quality. Look for something on M42 (pentax screwmount) since it can be adapted to pretty much anything for just a couple dollars. Yes, it's going to be more than £10, but it's very doable for well under 50, and you will get far better results than with those close-up filter things.
