Start the October with Flash

October has come ! finally it’s time for October fest or Halloween! Wait! There is still a time for a flash.
For those who interested in a flash might already know about this – but here is a quick explanation.
Any brand and model of flash has its own GN (Guide number) There is a formula to calculate the rage of Guide number = f-stop × distance (While ISO = 100) , blah…. blah… blah… Okay, skip it to the main part – I’ll called it as “Firepower” Every type of flash and model is what I said before, the GN should be on the box when you buy it. Anyways, I recommend you to have one and if you really want me to suggest a flash for you… I recommend you to try it by yourself at the shop. (Price and Quality – the one who pay should be the one who makes decision) Let me summarize it later.

For me? A Yongnuo, 3rd party brand should be enough. My wife saw it on the discounted shelf of the shop and gave it to me XD. Amazingly work, since 700D to 80D, then RP. Holy sh*t, I want a new one so bad, but it’s still working even I dropped many times. Let’s see what we can learn from this.

Mode – There are 3 of them that I have..
1. Manual – Fully adjust – range of the lens and firepower.
2. ETTL – is an auto range adjustment, still allowed you manage the firepower
3. Multi – While your camera shutter is open, the flash will flashes many time depends on what you set in Hz ( flashing/sec) – good for a long shutter speed. (Rarely use)

Jump to the manual mode. The basic start from here, since the cover image has a number of -2/3 it’s seem very familiar to you, right? if you read the older post of EV, That’s the same! what you need to know is how strong of flash will be – a firepower of it. You need to try it by yourself.
Next, the length of the flash (In a box “Zoom”) is the calculation of firepower.

“Again?” ,firepower, firepower – What is that? – The flash NEEDS RECHARGE its circuit – recycle time or a cool-down for a gamer word. Good flash has short recycle time with high GN. (Also, must cheap lol)
Recycle time usually appears in the manual or the box.
How does it work? – If the recycle time or the power on the charging circuits still enough, you can take Many photo till it out. If your model is posing in the perfect timing – your flash is on recycle = you f**cked up.

High speed sync (HSS) – This is a must for a late camera model, allows you to take a photo with flash in high shutter speed (faster than 1/200). If you don’t have – The photo will be half darken or fully darken. It means that the flash is release slower that your camera shutter.

Don’t worry that much if it is over exposure if you don’t have HSS – all you need is stay under 1/200, but you can increase the f-stop, the aperture. 🙂

Now, my experienced with this flash – I use it to avoid the model becomes darken or being a silhouette. Since the background is too bright.
