    In this assignment, I took the same image 4 times by varying the flash position including ambient light.

    Image 6252 = Ambient light
    Image 6253 = Direct Flash
    Image 6254 = Ceiling bounced
    Image 6255 = Wall bounced

    As I mentioned previously I want to push you a little harder than other students.

    I don’t usually do this but take a look at this assignment by John:

    He has done exceedingly well at showing he understands the quality of light as discussed in this assignment.

    Your assignment does meet the criteria for this assignment but I want to be honest here. These photographs are just not that interesting. I’m not sure whether it’s the dust on the glass or what it is but I just don’t like them. What’s more they just aren’t that different from each other.

    Now please don’t take this personally, this is just me pushing you harder! I promise.

    If you want to reshoot this that would be fine with me. The main thing is that you understand what the different types are light are.

    Let me know what you think.

    You’re right! I’ll redo the assignment. Those so-called ‘dust’ in the photographs, is actually lint from the paper towel I used to dry the wine glasses.

    Thanks for your honesty and your feedback.

    For the redo assignment, the harsh lighting was obtained by removing the lampshade; for the more diffused lighting, the lampshade was left in place.

    This is a much better example of what the assignment is asking for. So job well done here! Way to go!

    There are a few things to note here.

    Take a look at the details in the darks vs the highlights in these images.

    Your sensor can only capture some much whereas your brain and your eyes work together to see all of it. It’s interesting to compare the histograms as well from this perspective.

    Also take note of which image is more pleasing to the eye. Clearly in this instance the softer light image is more pleasing. So always think about what you’re trying to achieve. Do you want the image to be pleasing or harsh? Soft or hard?

    Sometimes you have no choice so you have to work with what you get. Other times you can control for everything. When you know what you’re dealing with you can shoot accordingly.

    Another thing here is that you should have wide depth of field than what I’m seeing with such a slow shutter and high fstop. I may be wrong but I feel like everything here should be in focus given the settings you used in both images. I suspect you’re bumping up against your lens’ minimum focus distance here.

    Take a look at the barrel of your lens. If there are distance markers on it take note of the shortest distance. If anything is closer to your lens than this distance if will be blurry. So maybe that happened here?

    Overall you’ve done a much better job here.

    One thing to remember though is to manually set your white balance. I suspect the color for these would be dramatically different and possibly more appealing if the white balance was controlled.

    Actually now that I think about this I suspect you’re using a macro lens and that explains the shallow depth of field. Please disregard what I said about the minimum focus distance!

    Onward!

    One final note here, I updated the lesson for this assignment and added a great video on this very topic.

    Although, you’re not able to tell from the photograph, I had the flower at a slight angle. I was having a lot of trouble with the depth of field. I know I still have a lot to learn. Do you have any suggestions?

    Good video!

    Thanks!

    Macro lenses present some serious depth of field challenges. You may have to try and use the Focus Stacking technique (quite advanced).

    Does that help?

    Here is a remarkably detailed look at focus stacking (Maybe too detailed)

    Thanks, Duncan! this video will be very helpful.
