I find the best way to use the iBlazr is as a continuous light source away from the phone, as it will be more directional to give definition to the subject.
Now to see if the light is strong enough for shooting photos, I did an experiment using the iPhone camera App. I set up to shoot the books on my book case at 1m, 1.5m, 2m and 2.5m away from the subject using the high continuous light mode (120 Lux); I used a tape measure to be accurate with the distance. Images were shot in a nearly completely dark room and were all then cropped in to the center. As you can see, it still emits enough light at 2.5m away from the subject for my iPhone to capture an image that is rightly exposed, albeit with higher ISOs.
Now the reason I did not use the iBlazr app for the above test is that I found the image quality was not as good as that shot with the iPhone Camera App. Also, it does not allow for adjustment of exposure in flash mode, which means that the closer subjects tended to be over-exposed. This makes me think that the flash mode basically emits full power (270 Lux) rather than adjust the output according to exposure required, which is not an issue for more distant subjects.
What is good about the iBlazr?
1) It has a power button which allows for different modes of using it.
2) It has good battery life and it is claimed to retain its charge for up to 3 months (unlike the Nova flash which will have discharged its battery fully by a few weeks).
3) It comes with a diffuser to soften the light.
4) The continuous light mode is particularly useful (not available on the Nova flash).
5) The colour temperature of the light is excellent as it is close to sunlight.
What could be improved with the iBlazr?
1) The flash mode on the App does not adjust the exposure down for close subjects, which results in overexposed images. Some may argue that for close subjects we would use continuous light mode instead, which is a fair comment.
2) The image quality of the App is not as good as the iPhone Camera App.
3) To use flash mode, it needs to be connected via the 3.5mm headphone socket (no bluetooth mode).
I think the iBlazr is a capable flash which does many things which the Nova flash is unable to do. It is certainly not a perfect flash, as it will not be able to capture motion like a true camera flash. But it can function very well to aid capturing better images, particularly with the continuous light mode. It is let down a little by its App, which really needs to improve in function. But use it with the iPhone Camera App and it can do very well.
