Flash Gels for Correcting Color Temperature: The Gels (Part 1)

My Gear - What you wanted to know but were afraid to ask_007Today's article is a 2 part concerning Gels.

A lot of people been asking me what are Color Temperature (CT) flash gels for and where they can find it.

On the first part I will be showing a very simple way where you can get them, in Europe, very fast and with everything you need to cover all CT areas.

On part two is all about practical examples on what and how you can use them on different situations to balance light and improve your photos.

I ordered 4 days ago a Filter Pack and an Effects Pack Gel from fellow photographer Jason Lane at flashgels.co.uk
at first I wasn't very sure which size to order because he has 2 sizes for different flashes heads, but everything is so well explain on the web site that I instantly figure out which to choose.

After exchanging some emails with Jason I realize that he's a Lone Ranger on this matter. He started this idea when David Hobby talked about it on the London seminar and since then he has been cutting the tinny little pieces of gels to match our flashes. Until now, I think, he's the only "store" who has them hand made, pre cut and shipped for and to the Strobist community and in Europe.

In another words he's getting us the gels we need to improve our photography and make them also in packages of Color Temperature and Effects.

The filters in the packs are cut from quality Lee Filter rolls and are 14cm long.
The 4cm Normal filters should be suitable for most Nikon, Pentax and Canon flashes (The one I ordered for My Canon 580EX and Nikon SB26) and the 5cm Wide are for flashes with larger lenses, for example the Vivitar 285HV.

He also have the Gels cut to 119mm diameter circles to fit the diffuser of the Quantum QFlash, if you have on of these units ;)

You can choose the Packs with Velcro or without. Packs with Velcro include 100 pre-cut 12mm hook dots for the filters, and 4 x 10cm strips of Velcro loops to stick on your flash. Loops are the soft side, hooks the rough plastic part of the flash.

Ball Bungees

And if you are going to buy, from Jason, do not forget to order a pack of the so hard to find Ball Bungees.

You may ask - "What are they use for?" - Take a look at these two brilliant articles here and here to know all about them.

At last minute, before this article went online, Jason added a new link on his web site where you can choose your own gels and make your own packs, he calls them Pick'n'Mix, they are packed on an envelope of 5 units each, you can get the same 4cm and 5cm gels with some extra CTB and other colors and add to the order some extra Velcro Hooks and Loops.

After this great last minute news the pack only depends on your color choices, just let him know what you need and he will make you the customized packs.

Jason Lane really do things a la Strobist way. You have everything you need in just one order and you get them very quickly. I was very impressed with the service and will recommend this to everyone who needs some Gels and Ball Bungees.

Gels Part1_001

Here is the package I received on the mail. Very good you can even use it as a box to store your filters while not in use.

Gels Part1_002

I've ordered the 4cm Gels pack with Velcro (£10.00-€14.02) and the Effects pack (£5.75-€7.98) that's £15.75 (€22.00) plus £1.30 (€1.80) shipping to Luxembourg total £17.05 (€23.80) paid through PayPal.

I think the price is really fair compared to all the cutting and packaging.

You can find more details and photos of the Effects Pack here.

Now let's make some DIY on how to apply the Velcro to the flash unit. Skip this part if you already know how to do this.

Gels Part1_006

I always like to apply Velcro after putting the Stofen on the flash this way it will not block it by any means and I can easily attach and remove the Stofen.

There are so many threads on the web about the Velcro attachment, some say they do not glue the Velcro, others say the flash stays sticky when you want to remove it and lately the talk bends to cable straps.

Take a look at the Flickr discussion group here and see what suits you best. Well me I prefer them sticky so let's stick them up :)

Gels Part1_007

With the Stofen on the flash measure the length of the soft Velcro you will be using and cut it.

Gels Part1_008

Now apply it to the flash.

Gels Part1_009

Do the same thing all around the flash and remove the Stofen. I like to make it all around just in case later on I will need to use a flag or a gobo to any side. You can ask what the hell is a gobo ???? Oh, no :( ...

No problem, take a look in here and you will find your answer :)

Gels Part1_010

Now the doted had Velcro.


Gels Part1_011

They go to each side of the gels, oh and by the way the gels fit perfectly on my Nikon SB-26 and Canon 580EX.

Gels Part1_012

Now you just have to put the gel over the flash from side to side, you can even put the stofen over the gel to get the tone to bounce all over (in case you need that).

Gels Part1_013

Tip: I normally put another piece of Velcro on the other face of the gel. I used here some pieces of the soft Velcro I've cut from the flash part.

Gels Part1_014Gels Part1_015

Here is what looks like. The circle are the hard Velcro and the rectangular are the soft Velcro.
On the other image I had previously done this with my other gels but then I only had the bigger rectangular Velcro. Well it's the same thing what suits best is what it counts.

Now you my say why do I need them on the both sides with soft and hard Velcro?

The answer comes with the next pictures...

Gels Part1_016

Simple... got it ?

Text version: You can use one gel on the flash while having another one (or several) attached beneath or above. This way would be very easy and quick to change them and you don't need to be running to your bag each time the room temperature changes say Fluorescent to Tungsten or vice versa ;)

Gels Part1_017

Here you can see them sticked together because one side has soft Velcro and the other hard Velcro.

Gels Part1_018

This image shows you what they both would look like on my Nikon SB-26 when stick together.

I have made some other articles concerning the gels and gel packs that you may look into them.

Lee Filters Flash Adapter_011

If you do not like the idea of the Velcro then you can make you own adapter take a look at the article DIY: Lee Filters Flash Adapter.

580Ex DIY:Color Gels_05

Or if you also do not want an adapter and you own a Canon 580EX or the new 580EXII you can make your own by reading this article DIY: 580EX and 580EXII Color Gels Printing Diagram.

StrawsSnootsWColor_005

You can even get your Black Straws Grid Spot with them check the article here.

Snoots with Colors (Part 1)_18

Or the Snoots. Article here.


I think this full package is very good and it has all the essential CT and Effects that you may need on a daily basis.

The only thing I missed on the Filter Pack was the lack of the Half Plus Green (245), the Quarter Plus Green (246), the Quarter CTB (203) and the .15 Neutral Density Half Stop (208) if they were to be included, in a near future, this would be the most complete gel pack for Strobist photographers even without these it still is one of the best gel packages I found over several online stores.

Delivery very fast and secure it only took 4 days from the UK to Luxembourg.

So what are you waiting for go and order one pack and be prepared for part 2 of this article "Flash Gels for Correcting Color Temperature: Using the Gels (Part 2)"

If your flash is not mentioned on the web site just send Jason an email maybe he could make a custom ones for yours.
