Photographing

For the last year this has been the bane of my life!!

I pride myself on being able to do or work out how to do most things but getting good product photographs has to be one of the hardest skills I have yet tried to master. I certainly have not mastered it yet but at least can now get acceptable results.

When I started doing jewellery I used a pair of Ikea desk lamps to light pieces and I generally just used by bench as a backdrop and had the items in their boxes. (see here) This was good enough for the purposes of documenting work and the black backdrop hid a multitude of sins. However if you try photographing an item on its own you need a lot more work to get a good result.

Traditionally silver would be photographed against a black velvet background but fashions have changed and colours and white backgrounds are the norm now. The problem is that if you screw up photographing black, you get a (to quote Father Ted) very very very very very very very very dark blue, or some other dark colour, which to to most people looks black. There is no need to get black of the backdrop to be priests socks black, just lay peoples socks black. However, photograph a white backdrop incorrectly and you get a definitely tinted outcome. This problem is compounded buy the fact that  websites often have pure white backgrounds so the contrast effect exasperates the situation and the tint is even more noticeable.

I tried white. I really did.But getting a white backdrop is actually quite hard. White paper, for example is often a bit yellow, white fabric shows every speck of fluff or hair it manages attractor and white perspex is very easy to scratch and shows fingerprints. So what to use?

Well going back to my bench photography days, wood is a good backdrop. the problem is it either needs to be shiny and new or old and battered.

You can see here how a small mark really shows up on this Ikea chopping board. Unfortunately the life scars on this piece of wood were to few and far between to be any use. All I got were pictures with dirty marks in them. Further more the scale of the grain is too big.

Here I used the wooden floor in mu house. Well battered, but again the grain is wrong, too small this time. (This is Ash wood should you be taking notes)

This one is against the raw ash veneered ply of a box easel, the grain is too detailed.

And here we have birch veneered ply. This is too light and it is very hard to get the colour right, the grain is a bit indistinct and a bit too detailed.

Finally I tried an off cut of redwood.

It has a good distinct and plain grain, it is quite yellow so any colour temperature adjustment doesn’t make it look fake and the know (the reason this bit of wood was cut off the end of a board) can provide some interest to the picture without being overwhelming. Further the graduation of grain lines means smaller things can be photographed on the left and larger things on the right.

It would appear that the perfect backdrop has a distinct texture that is about 1 order of magnitude below the size of the item and bit f colour to it.

With that in mind I went back to an old trick I had used a while ago, a cloth covered book.

Which I think works well.

Now for lighting!

Natural light is good. But 150 yeas of electrical illumination technology is more controllable. I tried with natural light outside but this was a bit of a disaster. The blue sky reflected in the silver and made everything look blue and cold. A cloudy day would be nice but getting enough light on a cloudy day I  found a bit of a challenge and that kink of limits you to photographing during the day and only on days where the weather is right.

Solution: ebay!!! I ordered a light tent for all of abut £15 and with that and some flashes I got better results but still poor. So taking the old adage that you can never have too much light (hey they filmed nuclear bombs going off and you don’t get anything much brighter) I also bought for all of £100 a set of soft-box lights. So now my set-up looks like this:

The side soft boxes have four 45w lamps in and the top one has a 135w lamp, all 5500K colour temp.

2 old books, my bit of wood and a plastic pot with some steel shot in it as a weight to hang the pendants from. The book that is standing up is up against a small wooden stand. Brooches are attached with a small blob of blu-tak when required. Hopefully I can now get everything photographed now.

Go look at my shop now and buy stuff to help me justify all this stuff. http://www.peterblacksart.com.

3D, its like 2D but with more D

For about 5 years I have been making jewellery on and off in my spare time. In all that time I have been using sterling silver. There are a number of reasons for this but the main one is price. At about 50p a gram you can afford to screw up and call it learning. At £25 a gram gold makes mistakes much more expensive. I would like to work in “The proper precious metals” but this has always been out of my financial comfort zone.

Until Now…

Thanks to the wonders of 3D printing you can now have anything made in anything pretty much. Most interesting for me is the possibility of 3D printed metal jewellery. There are two main technologies to do this. Print a wax part and do the lost wax thing or laser sintering which builds up the part from powder. Neither technology has really come out on top yet as an all out winner though. A bit like inkjet vs. laser, each has advantages and disadvantages,

So to try out this new technology I devised a fair and representative test. Send the same design off to 3 manufactures and see what comes back.

That’s not quite what happened.

First I drew a ring. This ring contained fine >mm areas and larger bulk areas. It had both convex and concave surfaces that curve in 2 directions and it had square internal and external corners. The ring shank was a relatively low polygon count and the knoble was a high polygon count.

It was drawn in blender and then exported as an STL.

synapse ring

So off it went to the people at i.materialise to be made in silver by the lost wax method and then to be delivered to be all shiny.

i.materialise.com only do silver and gold and nothing inbetween.so i wanted more options and the next company I tried was nextDayWax. However they claimed that the shank was too thin to sprue onto so I needed to redraw it. At this point I noticed a slight mistake in my previous drawing. I had intended then to fit my wife’s finger so that I could see them “on the hand” when they arrived and I had drawn the first ring 3 sizes too small. So I redrew the ring with the shank thicker and the ring the correct size.

synapse ring v2 correct size

I had this one cast in palladium and asked for it to be unhallmarked so that I could get it hallmarked with my sponsors mark but this message didn’t get to GoldMark, the company NextDayWax use to do their casting. As it was a test piece it wasn’t too much of a problem but a bit annoying

Finally I had the orignal design (scaled to make it the correct size) produced by cooksongold emanufacturing which is a laser sintering process and cooksons only do in 18K gold. Unusually for a 3D printing company cookson have quite steep sliding scale for production cost with one unit costing £203.90 +metal to £64.77+metal  each if buy 20 or more. They did gave me a “try your concept price of £61.16+metal since it was my fist order which I thought was nice of them. They are definitely the least slick in their web purchasing system though as you have to use WeTransfer to send the file which they then evaluate and send you a quote for which you then have to accept and if you don’t have a cookson gold account they then have to set that up, then when it’s made they send you a pro forma and you have to phone up to pay.

So now I have 3 sightly different rings in different metals to compare.

The palladium one I polished myself with abrasive silicone wheels and points. when it arrived it looked like this:
