    Bouncer71, Sep 16, 2018 :
    Hello..
    I'm Bouncer71...

    ...and welcome to premier of Bouncer71 presents "Fun with Lenses".

    bouncerpresents.jpg
    Over the next 52 weeks, you and I are going to explore the dynamic world of LensoLOLogie....
    What is LensoLOLogie …?
    Erm..?
    I have no idea...
    Sorry, got carried away right from the start...
    Okay, let me begin again... ;D

    Lenses and Filters covered in this thread:
    Macro, Circular Polarizer, Fish Eye, Neutral Density.

    Hi everyone,

    you all know those Clip-On Lenses, you´ve seen plenty of macro shots in the Monthly Threads, been mentioned in various other threads like one of my favorites by @BobbyVK [Let's Talk Response]

    But what are they for and how to practically use em?
    Whats Neutral Density? Do Star Filters filter stars...?
    Stay with me and see how to manipulate Light, bend space and travel in Time...

    Get your Lenses

    I Don't Like Clip-On Lenses...


    IMG_20180905_160437.jpg

    If you're fine with them, great..!
    To me it's kinda annoying to position them over and over again at the center of the camera lens to avoid distortion and vignette.
    Since I still have some 37mm filters from my Travel-zoom camera…


    IMG_20180905_160835.jpg

    I went DIY and ordered a Clip-On Macro Lens with the mount size. Cut off the clamp and put it on a wooden case with some double sided tape centered over the camera.


    IMG_20180905_160612.jpg
    No more fiddling around from now on...This might also be a solution for all you OP6 users out there. Position it over the main camera… No more Portrait Mode with that case...


    So, I´m all set and done, let's look at them lenses…


    Oops...
    Totally forgotten…
    You have to get yours…
    Thanks for the suggestion @NeVeR_SeTTLe ;D
    I can't give you the perfect recommendation which Brand to buy. It all depends on the budget you want to spend. You can get an almost complete sets for a couple of bugs or you can pay over a hundred Euros for a single filter.

    E.g.: 6 Filters ( 3x ND / CPL / FLD / UV) for 25 Euro, one Haida ND 3.0 for 35 Euro or one B+W ND 3.0 for 100 Euro.

    My credo is “Never buy cheap if the Lens or Filter extends exposure but don't spend the extra if it suits the purpose”
    The longer the exposure the more obvious the shortcomings will be in the photo, means harder to correct in post-edit or sometimes even impossible…
    Waste Time and Money..?
    Nope…
    A lens/filter that gives you good results will stay, and probably be used more often....
    And I want to go out, and use em´….
    Like Haida ND is a good compromise for me...


    So let´s get to it…!


    Macro Lens

    Yep...
    Just gotta love Macro…
    Probably the most popular add-on lens.

    IMG_20180905_120936.jpg
    ZOMEI 12.5 x


    Used for magnification and you can get closer than the usual ca. 10 cm. In the description a lot a times magnification is called diopter. But how much is 8 diopter...?

    There's a formula for that.

    Magnification = (Diopter/4) + 1

    or vise versa

    Diopter = (Magnification - 1) x 4

    So 8 diopter is 3x magnification.

    But wait, before we´re going to take a photo. Have you ever seen this...?

    [​IMG]
    It´s a Macro Focusing Rail...

    I don't want to say to shoot your macros necessarily with a tripod, but we can learn something from this tool..
    The depth of field is pretty narrow, a couple of mm at most. Using autofocus can be troublesome or constantly manually focusing causing a thumb spasm...
    Set the manual focus once and change the distance to the object till in focus, just like moving the camera on the rail back and forward.

    too far…

    IMG_20180905_115817.jpg

    just a bit closer and
    IMG_20180905_115819.jpg
    perfect…
    Way more comfortable..

    For Focus-stacking I´d recommend a tripod and the rail cause of uncontrollable camera movement. The lens-distortion and different object size is already hard enough to cope with.
    And use a remote trigger to prevent camera shake caused by tabbing the trigger on screen.

    Screenshot_20180912-160425_copy.jpg

    Probably gonna do a separate thread about Focus-Stacking if I find a practical easy way to do it with a smartphone and the perfect apps… ;D
    But I still got a long way to go...
    Have you got a solution…? Please tell me…!!! 8D


    CPL – Circular Polarizing Filter

    Works just like polarized sunglasses, it suppresses reflections.
    Don´t ge me wrong. Reflections are great in Photography...

    [​IMG]
    Photo by @jacstrong

    But sometimes it's just distracting...
    When light is reflected of a surface it changes it´s polarization. By turning the filter you can manipulate what part of the light travels through it and hits the sensor.

    Shooting through a window or reflections on water that don't fit the picture...
    IMG_20180905_122424.jpg
    Turn the lens until satisfied with what you see...

    IMG_20180905_122433.jpg
    Delmax CPL

    The pic gets a little darker so you might want to exposure compensate a bit or brighten it in post.


    Fish Eye Lens

    This is Lens-distortion at its best... Cool effect...

    IMG_20180905_152652.jpg
    Hama Fish Eye Lens

    I don't really like the vignette and haven't found a good use for it personally...
    Someone got a more enthusiastic approach out there...?
    Would be appreciated with full credits... ;D


    ND – Neutral Density Filter

    This is one of my favorites. You become “The Master of Time and Light”...
    But it doesn't come with just a click…

    Also called Neutral Gray Filter they are like really dark sunglasses for your camera. As you know if it gets darker, exposure time has to be longer or ISO will go higher, or both...
    What if you want to extend the time to capture motion instead of just freezing a tiny fraction in time…?
    Okay, you can do a long exposure at night. But what about in bright daylight at ISO 100...?
    With the right ND-Filter even light-painting at noon is possible...


    The Basics:
    There´s different stages of neutral density. The higher the ND number the higher the exposure extending factor.

    ND / Factor / Light transmittance
    1.8 / x64 / 1.8%
    2.0 / x100 / 1.0%
    3.0 / x1,000 / 0.1%

    8.0 / x100,000,000 / 0.000001%
    ( One Hundred Million that is... 8O )

    There are also variable ND-Filters with a max. factor of x400 available but it's harder to determine the exact exposure. Cheaper ones are not really neutral and have uneven transitions.
    Manufacturers label the filters with the factor. But mind the point…! Filters label with ND 8 have just a factor of x8. ND 64 would then be ND 1.8 or ND 1000 = ND 3.0.
    So always have a look at the description...

    I recommend to use a tool to calculate the needed shutter-speed settings like Foto-Tool
    Also features some other interesting calculators...
    Screenshot_20180907-082658_copy.jpg
    A tripod, remote trigger and to shoot in RAW cause post-process is unavoidable to keep as much details as possible.


    Preparation:

    Setup your camera on the tripod without the ND filter. Select Pro-Mode, frame the scene, manually set ISO 100 and the focus, tab to exposure on the brightest part of the scene (the sky between the trees) and shoot a photo…

    JPG untouched
    IMG_20180905_131806.jpg

    Take a look at the exif info.

    Screenshot_20180907-082417_copy.jpg

    Use the app to calculate the exposure for the used ND filter..

    Screenshot_20180907-082741_copy.jpg

    Set the exposure accordingly or close to the calculated values in Pro-Mode and apply the filter.
    Click and wait...

    Haida ND 3.0 slim / 2.0 sec. / Untouched / JPG
    IMG_20180905_132704-2.jpg

    You can clearly see the difference. The water surface and the fountain gets kinda fuzzy and the effect is stronger the longer the exposure...

    And another one before we're going post...

    Going Post


    Now, as I like to say, the fun ( erm... work) begins.
    As you see in the examples even the JPG look a little dull. Lost saturation, highlights and shadows are a bit overblown. That is why I always shoot RAW using ND filters.

    Edit with your favorite photo manipulation app.
    Saturation, dynamic, clarity, highlights, shadows ,contrast etc. need some tweaking to give it the right looks...

    IMG_20180905_142136.jpg
    And done…

    Not bad for a smartphone camera, not bad at all…
    Btw, notice the turtles…?

    This is why I got them ND Filters 2 years ago..

    Just love the dynamic of these long exposures…!

    Wide Angle Lens (added 03.10.18)

    IMG_20181003_105533.jpg

    There´s a lot of users wanting a secondary wide-angle lens. Though it's nice to have a wider field of view it comes with a downside. Just like the fisheye lens it distorts the picture.

    Well, more information has to be fitted in the same format. Squeezing it all in plus optically bending the photo towards the edges.
    I'm using a 140° Super Wide Angle lens by ZaKitane.

    Without…
    IMG_20180926_164423.jpg

    With wide angle at the same position...
    IMG_20180926_164441.jpg
    Clearly far more field of view. In this scene you probably only notice the distortion if you take a close look. The squares are a bit off the equilateral and bend…


    Using Lens Correction in Lightroom can help to even it out but it will also cause cropping the picture.I actually don´t mind the distortion. But what always hits my eye is the changed proportions of objects. I use a pretty simple method to milden the effect by resizing the pics width…
    IMG_20180926_164441-Bearbeitet.jpg
    Hight = 100%, Width = 107%


    You could also step back a couple of meters and get a similar result without an wide angle lens…
    IMG_20180926_164533.jpg
    meh….
    Should have added another step… ;D
    But i think you get my point… It doesn't make much sense to use a wide angle just to cram more stuff in the picture…
    For situations you can´t step back, like standing in first line in front of the Trevi Fountain/ Rome and a couple of thousand other tourist like you standing in line to take your place that might be ok… But even then a Panorama is the better solution...

    Why to use the wide angle lense then…?

    Something completely different…
    Drawing attention, enhancing the illusion of depth and space and having more crop options..
    It's more or less and artistic lens imo…

    E.g. Straight out of camera...
    IMG_20181003_145648.jpg

    Wide angle lens applied
    See the red stone in the bottom left corner it's almost at the same place but the field of view drastically changed...
    IMG_20181003_145738.jpg
    After post, crop and lens correction...
    IMG_20181003_145807.jpg
    This crop would not be possible without wide angle…

    Another example
    Without...
    IMG_20181003_144213.jpg
    With wide angle cropped and lens corrected
    IMG_20181003_144100.jpg
    And I really like the lens flare it causes… 8D
    IMG_20181003_142751.jpg

    We´re done...


    This concludes today's episode and I think I showed, though it's not always simple to use add-on lenses and filters, it's easier than expected.

    Thank you for staying with me and I hope you didn't fall asleep while reading…
    This all, is just to get you going. There´s more comprehensive Tutorials out in the Web.
    As always any comment is appreciated and now…

    Go out there and use some Lenses….!!! 8D

    To be continued…?

    P.S.:
    You want to use your phone like a DSLR…?
    Just do it…!
    Go Pro-Mode… ;D

    18X zoom lens sample:

    It was too tough to capture this, used 18X zoom lens. Had to take over 100 shots to get it this stable as the subject is moving (fast) and any slight movement to adjust the view causes blur. Cropped to 16:9 & rectified perspective to eliminate the lens distortion

    Thanks for the pictures..!
    Great macro.. ! 8D

    The kaleidoscope is kinda weird...

    Still don't know what a good use for the fish eye would be...?

    The 18x Tele seem to be a slow lens and everything is blurry. Maybe better used with a tripod, manual focus and a tripod...?

    Well my friend you've got endurance. No doubt about that.. 8D


    Thank you very much...!
    It's my pleasure.. ;D

    Talk to me when I show you Kaleidoscope 6.
    I seriously don't understand why they've included in the package.

    I got even more weird lens - star & flow filters. I mever use them. But bought the package 10 in one as its at a good price and that's the only way I could buy a CPL lens in a kit.

    TBH I'm not a fan of fisheye lens. Need to experiment more, but time constraint.

    Getting a tripod does wonders, but I'm not sure if this particular lens needs one, I should be investing in better quality lens + tripod. This one is covering my cam module.

    hmm..
    I could think that kaleidoscopes have an better effect close up to the object or with geometric forms in the scene like architectural shots...

    I have some star filters too...
    they are quite nice but I need to find a scene where they really pop...
    Too many light sources and it's a mess... 8D

    Thank you very much..!!!
    Not that you didn't have a preview...;D
    And thanks for the suggestion again...!
