I've seen one or two guides to using 645 PRO recently, but these have been little more than a reprint of the apps user guide, which is an essential read if you want to fully understand, appreciate and get the best out of this fantastic camera replacement app.
So, in this post, I'm not going to go into full detail about all the apps features and settings (you really must read the manual for that), but instead share with you my now preferred 645 PRO setup.
First up, let's look at my under the hood settings, which can be found in the iPhones settings menu. Basically I've got everything set to OFF except for the Hi-Vis shutter (this makes life a lot easier when shooting in daylight conditions) and TIFFs -> Camera Roll. Q-Mode TIFFs are left on the default setting, which is JPEG + TIFF. I then have my name set as Artists name, Copyright set as [Year] [Artists Name], and last but not least, License set as All Rights Reserved.
So having covered the hidden bits of 645 PRO, let's take a closer look at my 646 PRO camera settings. Having played with the film backs and format options, I've decided to shoot nearly 99.9% of the time in Q-Mode (which is 645 back (format) with no additional film or filters, and is activated by double tapping the film dial) and lossless JPEG (although if I was shooting with an iPhone 4S, then this setting may be different, and include TIFFs). Why have I decided on these two options? Well whilst I have found the results from the film backs and optional filters to be exceptionally good, I prefer to edit (if needed) with Snapseed, and so this Q-Mode setup offers for me, exactly what I need, and that is reasonable file sizes (the TIFFs are large) with the best image quality possible from my iPhone.
So, that's the shooting format and quality aspect of the camera settings out of the way, now let's look at the rest of my settings. Starting from top left, I have the Flash set to off (I never ever shoot with the iPhones flash, as like any basic flash unit, the results will always be disappointing). Next up, the Grid, which I have set to full (or maximum grid lines), the Meter set to Spot, as I have found for me this produces the most accurate exposure for my subjects. Then there's the White Balance, which seems to always work for me on Auto (AWB).
Taking photos with 645 PRO. With my default set-up above, taking photos with 645 PRO is a breeze. With the iPhone not in silent mode, I simply point the centre spot at my subject, then press and hold the (Hi-Vis) shutter button until I hear a double beep, which locks in the focus and exposure at the same time. Then I recompose if necessary, release, and quickly press the shutter again to take the shot, to the sound of the shutter firing, and that's it.
In general I find my simple yet effective set-up produces near perfect shots every time, as my sample (unedited) photos taken whilst holidaying in Cyprus show.
Tip. If you decide to shoot as I do, in Q-Mode, then set the camera back to 6x17 (you'll need to do this whilst not in Q-Mode), so that if you accidentally switch modes, you'll instantly know by the letter box view.
