When I use Center of Interest Well, It Sounds Like I am Using Rule of Thirds. Is This True?

Great Question:
Hi Say,

I have read about both center of interest and rule of thirds and am a little confused between the two. I know for rule of thirds it is best to place the subject in one of the four intersections on the grid. However, center of interest also says that usually the subject is not placed right in the center, which kind of makes it rule of thirds, right? Are these two pretty much the same? If you could further explain to me the differences or similarity between the two that would be great!

Thanks

 

Answer:
Thanks for your question.

Center of interest just means having a strong subject or something of interest. Often, photos that have better eye movement throughout the photo when the subject is off center – like the rule of thirds. When you center something in the photo, it becomes more like a target and less like a subject in its environment. This means your viewer looks at only part of the photograph, not all of it. The idea of using composition well is to create eye movement from your viewer throughout your photo, not just the center of the photo.

We use ‘centering’ well when we want the subject to have a sense of isolation or the photo is of a product shot with a clean background…. or mugshots. In mugshots, the idea is to be able to identify a person and nothing else is important. When we photograph people in the center of the framing (school portraits is another example) it’s best to work to keep the eyes in the rule of thirds. Otherwise, try photographing your model off center (like the rule of thirds) and see how much more interesting your photos are to look at.

Keep in mind, composing a photo is all about experimentation. Sometimes when I photograph something I will bracket the composition. This means I will take the photo horizontal, vertical, using thirds, breaking thirds, move around to get a different angle. Often, my first photo is not the strongest. It’s when I start playing with the composition that I find I can create a more compelling photo.

In a nutshell, using more the one rule at a time to create a photo often creates a stronger photo that is more pleasing to the eye.  If this means that your subject (center of interest) is in the rule of thirds, then that is great!

Hope this helps,

How Do I Work with BDE?

Great Question:
I also have a question about the basic exposure formula. I don’t really understand how I would set the exposures. Does the ISO determine the shutter speed and aperture setting? I’m not really sure how it works.

 

Answer:

Before I start in on BDE, let’s back up a step and answer your ISO question.  ISO settings tell your camera how sensitive to make your sensor.  If you have your camera set to ISO 100, then it is less sensitive to light and is best used in daylight or brightly lit areas that mimic daylight brightness.  When you double your ISO number, you make it twice as sensitive.  So 200 ISO is twice as sensitive as 100 ISO.  Imagine you are in a room where there are two lights with the same wattage right next to each other and both are turned on.  If you create a properly exposed photograph at 100 ISO, you could also get a same properly exposed result by turning one of the lights off and correcting only  your ISO to 200.  Because you made your sensor twice as sensitive to light, when you cut the light in half the photo will look the same.  Cool, eh?

This doubling of sensitivity is called a “stop”.  Continuing on from 100 ISO to 200, I would say that “my sensor is one stop more sensitive.”  If I doubled ISO 200 to 400, this is also considered “one stop more light” into the the camera.  (Technically, the same amount of light is going into the camera, but we photographers are not alway so technical in the way we speak.)  😉  Now a quick quiz for you…. If you changed your ISO from 100 to 400, how many more stops would you have increased you light into the camera?  Did you say two?  If so, give yourself a pat on the back.  Every time you double the ISO (100, 200, 400, 800, 1600) you are doubling the light sensitivity of the camera.  So, ISO 100 to 1600 is a change of four stops more light.  Got it?  Cool.

Now for something to pay attention to.  When you change your ISO from 100 to 1600 you are moving four stops, but this does not mean that you have “increased your light” by 4 times the amount of light.  Remember, you are doubling the each stop.  This means that you are creating the simple equation of 2 x 2 x 2 x 2 = 16 times more light.  (Ooooo, that is a good quiz question, don’tcha’ think?)  😉

We have been talking about doubling the light each stop and I have a feeling that you are starting to get your head around it so I am going to reverse the scenario for you.  Imagine that your ISO is set to 400 and you want to bring it down to 200.  What happens then?  Naturally, you half the amount of light.  So ISO 400 to 200 makes the sensor 1/2 as sensitive.  The halving of the half also goes into play when you move more than one stop.  How much less sensitive is 1600 ISO to 100?   If it helps, think like  you are using measuring cups.  You start with a full cup, go down to a 1/2 cup, then down to a 1/4 cup, then down to an 1/8 cup, and finally down to a 1/16 cup.  So when you change your ISO from 1600 down to 100 your sensor is 1/16th less sensitive.  This is like taking 16 lights of the same wattage and then turning them off until you are using one light.  That is a big change.

Whew, that was a lot of take in.  If you need to look up and take a breath before we move on, please do.  🙂  We are about to dive into BDE.

Ready?  OK, go get your camera if you want.  Sometimes it’s easier to understand what is going on if you dial in the changes.  If it gets to be too much, then just let it be a supporting friend next to you.  😉

BDE (basic daylight exposure) is pretty easy, but let’s start from the beginning.  In the real-world, BDE is known as the Sunny/16 rule.  Technically, BDE = ISO @ f/16 on a bright sunny day.  (This is another good quiz question.)  So on a full-sun day with no clouds nor haze blocking the sun’s light, your exposure when your camera is set to ISO 100 will be 1/100th of a second at f/16.  As we are working in full stops this term, we adjust the shutter speed to be 1/125th of a second.  (The tiny quickening of the exposure will not affect your exposure much.)  Essentially, on a bright sunny day, you will:

1. Set your aperture to f/16
2. Set your ISO to a number that feels good for you – usually 100 or 200 is better for full sun
3. Then you will correct your shutter speed to match your ISO

Easy, right?

Now I know what you are thinking, “Yeah, that’s easy, but what do I do on a heavy overcast day?”  Another great question, thanks for asking.

On a cloudy day we have less light making it to the earth.  The clouds are blocking, absorbing, and reflecting some of the sun’s light and we just does not reach us.  This means we are going to have to adjust our exposure so that we are allowing for this lack of light.  We can make this adjustment one of three ways:

1. Increasing the ISO – 100 to 800
2. Opening up our aperture – f/16 to f/5.6
3. Slowing down our shutter – 1/125 to 1/15 of a second

NOTE: You only need to change one of the tree options, not all three at the same time.  Making all three changes will give you a completely overexposed photo.  You don’t have to trust me, try it out outside.

Back to the lesson: I am betting you noticed that I have let in three stops more light with my exposure for each of these options.  How do I know to ‘open up’ the exposure by three stops?  I checked my handydandy BDE cheatsheet found here –  http://wfs.sbcc.edu/Departments/GDP/photo109/htm/befcheat.htm – and in our Resouces section of Week 2.  For heavy overcast days, it tells me  BEF + 3 Stops.  The “+ 3” is telling me to add 3 stops more light to my exposure from the BDE.  It is a good idea to have this cheatsheet with you when you photograph so feel free to print it out and stick it in your camera bag or photograph it with your phone and then mark it as a favorite so you can access it easily.

Please keep in mind that you do not have to change only one option above to get the correct exposure.  You can pick and choose what you want to change, but you only need to brighten your exposure by three stops.  You can increase your ISO by one stop and slow your shutter by two stops.  You can also adjust all three by one stop more light.  Let’s take a closer look at this.  First I am going to set up a full stop range of ISO, apertures, and shutter speeds so that you can refer to them as needed as I make exposure adjustments.

                 ISO: 100  200  400  800  1600  3200

         Aperture:  f/1  f/1.4   f/2   f/2.8   f/4    f/5.6   f/8      f/11     f/16     f/22      f/32      f/45

Shutter Speed:  1′   1/2    1/4   1/8   1/15   1/30  1/60  1/125  1/250  1/500  1/1000  1/2000  1/4000

Here all some examples of equivalent exposures:

ISO 100 f/16 @ 1/125  – This is BDE for a bright sunny day before the adjustments for heavy overcast

ISO 800 f/16 @ 1/125 – Increasing only the ISO by three stops

​ISO​ 100 f/5.6 @ 1/125 – Opening up only the aperture by three stops

ISO 100 f/16 @ 1/15 – Slowing down the shutter by three stops

ISO 200  f/8 @ 1/125 – Increasing the ISO by one stop and opening up the aperture by two stops

ISO 400 f/16 @ 1/60 – Increasing the ISO by two stops and slowing down the shutter by one stop

ISO 100 f/11 @ 1/30 – Opening up the aperture by one stop and slowing down the shutter by two stops

ISO 200 f/11 @ 1/60 – Increasing the ISO by one stop, opening the aperture by one stop, and slowing down the shutter by one stop

​We can keep going with the potential equivalents, but I can see your eyes are starting to glaze over from here.  🙂

OK, that was a lot of information.  If you need to go through it a couple times, please do.  Once you have this down, you understand the backbone of creating properly exposed photographs.  As photography is based on the speed of light, this will never change.  🙂

What Are the Basics When Buying/Renting a Camera?

Great Question:
I am working on preparing everything for the class now. I called Sammy’s and they were very helpful. I will go there tomorrow to check out cameras. Thank you so much for that. One last question about the camera. Is there any additional gear that is mandatory to rent with a camera? Or, if I wanted to purchase one, are there any special lenses I need to be aware of getting as well, or is everything usually included?

Answer:

Yes, the guys/gals at Samy’s are great!  Be sure to let them know you are an SBCC student everytime you shop there for discounts.

With the camera rental/purchase you will need:

• Camera
• Lens – No special lens needed.  A basic zoom will work or if you are on a budget pick up a cheaper 50MM lens
• Memory Card
• Battery – If you can get two, that would be better
• Battery Charger
• Cable to connect the camera to your computer or a Memory Card Reader
• Camera Strap – then be sure to use it  😉
• Camera Bags are handy
• Camera Manual – can usually be found online
• Proper lens cleaning cloth is also good.  Don’t use your t-shirt if you use fabric softener.  The oils in the softener will eat up the lens coating that you paid for when renting/buying a lens

​I would imagine that the good people of Samy’s would have you set, but it’s good to double check.  We all have our off-days.

Thanks for asking,

Resizing in Lightroom and Photoshop

Great Question:
How do I go about trying to save my photo to make sure it meets the assignment requirements?   I used Lightroom CC but was unsuccessful and proceeded to try Photoshop and it worked on there to just save it in the format required for the assignment. If I need to clarify please let me know! Thank you for your time!

 

Answer:

Quick Steps on Exporting Images in Lightroom:

1. After you have imported and processed your photo(s), go the the Library module at the top right-ish corner of Lightroom
2. Choose the photo(s) you want to export in the film strip at the bottom.  You may hold down the Command/Control key to select more than one photo
3. Click the Export button at the lower left corner of Lightroom
4. In the new window, work your way down
   1. Decide on your export location and if you want it in a sub folder
   2. Custom name the photo(s) to the assignment’s requirements
   3. Correct File Settings to:
      1. JPG
      2. AdobeRGB (1998)
      3. Quality is 80 or higher – the higher the number the better the quality but also larger files
   4. Resize to fit the Long Edge to 1920 pixels at 72 PPI
   5. Do not output sharpen
   6. Include All Metadata – but remove Person Info and Location Info if personal
   7. Do not watermark your photos for this class
5. Click the Export button

Here is a sample of how the window should look.

Quick Steps on Exporting Images in Photoshop:

After you have opened and processed your photos, you will want to resize them for submission.  When you resize in Photoshop, you are changing the actual size of the original image if you save it under the same name.  As we are sizing down, this means that your 1920 long images would not be good to print any bigger than a couple of inches in finished size.  To save your large files size, follow these steps.

1. Process your large photo so that it looks like you want it to
2. Save your large photo
3. Go to File > Save As and save your large photo again with the assignment requirement name
4. Resize your photo by going to Image > Image Size in the top menu
5. Change the Resolution to 72 PPI first
6. Correct the longest side to 1920 pixels
   
7. Click the OK button
8. Go to File > Save As and save your now smaller photo as a JPG from the drop-down menu

Now all you will need to do is log into Canvas, go to the assignment, and click on the Submit button at the top right of the assignment to upload it.  Please remember to include your exposure notes in the Comments area of the upload.

 

How Do I Resize Photos in Apple’s Photo App?

Great Question:
The only app I have on my computer is the “Photos”.  I don’t have any apps that will allow me to size and save images. Would that app work or are there other apps you would recommend?

 

Answer:

Hi,

You should be able to file size in Photos.  Here are the steps you can follow:

1. Highlight the photo(s) you want to export
2. Go to File > Export > Export [#} Photos
3. In the new window, click the downward facing carrot to the far right of Photo Kind
4. Then in the expanded window, fill out your selections as below (You won’t be able to choose 72 PPI, but that will be OK.)
5. ​Click the Export button

Let me know if this does not make sense.

Otherwise, you can download, install, and use GIMP (Links to an external site.) for free.

How do I know which image is my original when I make a virtual copy?

Question:
If I make a virtual copy, how do I know which is the original and which one is the virtual copy?

Answer:
This is a great question. Of the stack, the first one is always your original. The ones after that will say they are copies in the file name just above the filmstrip. Here is a video to help show you what I am talking about. http://screencast.com/t/5JY3oQaX6ki

Adding Images to Discussion Boards

Question:
Is it possible to upload two images (before and after) at the same time?

Thanks!

Answer:
This is a great question.  Yes, you can.  You will need to upload one image, then move your cursor to the new position you want the second photo to show and upload the second image.

To upload photos, start by exporting/saving the photo as 72 PPI JPGs at 1000 pixels in length on the longest side.  (You can upload larger photos, but you may run into storage space limits later, so it’s best to upload only the size you need to show.

Once you have your photo(s) ready, follow these steps:

1. Click on the “Reply” link below to start a new post.
2. Click inside the area you will type your response in.
3. Click on the mountain with the sun icon in the edit toolbar at the top of your post.
   
4. Click on the Canvas tab.
5. Select where you want your photo to upload by clicking on the My files folder.
6. Click the Upload File button to the bottom, right of My files area.
7. Navigate to the photo  you want to upload on your computer and click on it.
8. Click the Open button.
9. Add a simple description of the photo in Alt text box.
10. Correct the Dimensions so the the longest side is 1000 pixels.
    
11. Click the Update button

What steps to you take to clean your lenses and sensor

As for cleaning lenses and sensors, you have to figure out what works best for you.  Watching Youtube videos is a great way to start.  I HIGHLY recommend watching at least five, but closer to ten or more GOOD Youtube or Vimeo videos on how people clean each piece of equipment.  You want something that works well for YOU.

Do keep in mind, you should never use cotton swabs or canned air to clean either.  Cotton swabs fall apart and leave lint on and in your gear.  Canned air has a propellant in it that will cause anything it touches to become sticky.  Over time the challenging sensor to clean will become impossible.

As for me, here are the highlights of what I do.  Do keep in mind that I do not apply a lot of pressure.  I use more repetition to get smudges or dust lifted.  (Note: the links listed are meant to only better show you what I am talking about.  You may like these or want to use something else.)

Lenses:

1. Blow off the lens with a Rocket air blaster to knock off large dirt.
2. Gently wipe the lens from the outer to the center with a clean microfiber cloth.
3. I do not breathe on the glass.  Breathing on the glass can produce spit on the coating, plus it adds bacteria to your glass.  This bacteria can grow into something that eats at your non-glare coating.
4. If a smudge will not lift, I do put some lens cleaning solution on my cloth and start wiping gently again from edge to center.
5. I have used the Lens Pen to clean off fingerprints.  I do start with the brush end first and then carefully start by cleaning the outer edges of my lens and moving toward the center of the lens.

Sensor:

1. I make sure my battery is fully charged and that I am not in a hurry at all.  Cleaning a sensor will take time.  I go in when I don’t have anything else to do and am not in a hurry at all.
2. I clean my sensor in a clean bathroom.  I choose the bathroom because I run some water for a short while to bring the humidity level up a touch (NOT steamy) and thus help to bring down any dust.
3. I set my sensor cleaning solution and sensor swabs (note: this link is to full-frame sensors, if you have a cropped frame, get the correctly sized swabs) so that they are ready to go and can be used with one hand.  I will use at least three sensor swabs.  These prepped swabs will lay on the side of the sensor box with the end that is going into my camera hanging off the edge of the box so that they are not touching any surface.
4. Once I a ready, I will get the first sensor pad moist with the sensor cleaning solution.  Less moisture the better.
5. I then put my camera in sensor cleaning mode under the Menu options.
6. Keeping the camera body so that the opening is facing down, I take the lens off the camera.  I then inspect the lens to make sure it is clean and cover it with the proper cap.
7. Next, I pick up my camera so that the hole is still facing down and then I take the moist swab and place it on one edge of my sensor.  I then gently swipe the swab from left to right.
8. The camera is still facing down.  I am raising it above my head.
9. When I reach the other side, I gently move the swab down the sensor edge without lifting it off and then gently swipe back.
10. Again, I am not in a hurry.
11. I do this until I think the sensor is sufficiently moist.
12. I then place this moist swab down and pick up a new dry one.
13. I then do the same edge-to-edge swipe and then move down on the edge to swipe back to the first edge.
14. This is done until I see streaks.
15. When this happens, I move to the next dry swab and repeat until the sensor no longer shows streaks.
16. At this point, I put the clean lens back on the camera and retest it to make sure the dust is gone.
17. If it is, then I go on with my life.
18. Often it is not, so I repeat the process until the sensor is clean.
