Default FREE coloured filters for your speedlight!

This question popped up recently so I thought I'd stick some of the info in here to help anyone out.

Basically, its possible to change the colour of your flashgun, and best of all it's free! First of all you have to order a free swatch book from Rosco that gives you a whole selection of colours to choose from, the great thing is that these are a perfect size to fit over your flashgun head.

The book looks like this,


and it can be ordered from the UK site here: http://www.rosco.com/uk/filters/index.asp

(couldn't find a link on the US site but I'm sure if you send them an email they will let you have a book!)
*EDIT=CDS* U.S. Web site ;
http://www.rosco.com/us/filters/index.asp
Links to request samples at bottom of each gel page.


Once you get your filters, you have to figure out a way to attach them to your flash head.


This is the method I have come up with

All you need is:
some duct tape
pair of pliers
paperclips

Firstly bend the paperclips into a right angle using the pliers. I used four paperclips.



Now, simply attach them to the flash head using strips of duct tape. I put one clip either side and two on the bottom (to stop it wobbling). I left the top free so that the filters can easily be slid in and out.



I did the same to my other flashgun...



Finally, remove the filters from the book. The filters need to be trimmed to fit the holder. For my 430ex I simply cut off the end up to the hole that is cut into the filter. (They look better too with no holes in them).



They should fit your holder perfectly, and they are very easy to add and remove (and you can obviously stack them too if you want to).




There you go! simple! I just wanted to show my method of doing it as I have seen a lot of people using velcro. Whilst I haven't tried it it looks fiddly, the filters are more difficult to remove and you can't stack them. So I just thought I'd offer up an alternative.

If anyone wants to add anything go for it! I know nothing about colour temperatures... (well I know how to warm up or cool down a flash!) so if anyone knows of specific filters in the swatch book that warm up or cool down a flash to a certain temp then that would be useful.

Have fun!

Stu

warmer = more yellowish.
cooler = more bluish.

Great idea. Could be shot through a translucent umbrella for a nice effect in a studio.

On the other side of the pond, they're available at B&H for $0.01 plus shipping. Search the B&H site for "Roscolux".

For those interested, my method for attaching these is pictured in this thread.

Stupot, have you tried just pulling out the wide angle diffuser and sticking the gel underneath?

Yeh I just thought that since it put the flash on its max zoom it would be losing some light, which might not be great if you're already cutting light using filters. Good thing to do to try it out though, especially if you dont want to stick anything to your flash.

Just got my sample a couple of hours ago. So I haven't worked it out yet. But I have this preliminary observations.

(All subsequent data from Photonotes: EOS Flash):

Flash is about 5500 ēK.
Tungsten (depending on voltage and age): 2900 - 3200 ēK (older is lower)
Fluorescent: 4900 - 5300 ēK (depending on spec - daylight, etc.)
Candle flame: 1400 - 2000 ēK

Some of the Roscoe samples are marked with the colour shift they produce. Just look them over. And I will also try them.

Let me know if you get more accurate numbers.

3 days from the US into Chile and my home (they were custom-free due to the low value). Placed the order Wed 10:30 AM and got them Fri 3:30. I used UPS but Express Mail would have worked the same (maybe a couple of days extra).

You have to include something else or the shipping charge will be prohibitive. Actually, the lens cleaning fluid I bought was free on this account.

P.S: I bought at B&H

I've sent off for mine - I hope they arrive soon

I'm thinking that I'll do something similar to you (stu), but I'll leave a side clear of hooks and put them along the top, and slide them in. That way I'll be able to mark the number on the bit that will stick out (with the hole) and I'll know more about the filter

leo - sounds good. you've also got a bit sticking out to put your greasy mitts on.. rather than smearing them all over the filter so prob a good idea.

Data in this thread might interest you.

I also calculated the color temp of the flash with the various Roscolux swatches attached. They all reduced the color temp reasonably close to specification, though the result was higher because the naked flash is higher than 5500K.

Tungsten light fixture in my dining room measured at around 2100K.
