Re: The Fundamentals of Photography

I sometimes use the Photoshop vignetting by going to Filter-Distort - Lens Correction! Uncheck the grid, then use sliders under vignette! You can then create the effect that you may need!

That's a good tip, will give it a try thanks for sharing.

Good idea, I did do something on the basics a while back, last year I think, even if it helped one person then it was worth while, after all its all free and we are all here to help each other, and praise the lord for photography, and thank him for the gift that he has given us to express our creative inner thoughts to express our feelings in such a loving way! Amen.

Re: The Fundamentals of Photography

One quick and simple way is:
Make a very loose selection (any type ..freehand,oval, circular etc) around the subject.
feather at 90 or more
invert then floodfill with a colour of your choice.
When you see what happens you can adjust accordingly

Re: The Fundamentals of Photography

I must say I enjoy living in Hong Kong, never thought that I actually work less hours, starts work around 11am to 7pm, five days a week, pay less tax and having more time for my photography. Everything worked out much better than I ever expected, because the highest income tax here is only 16%, 70% or so of the population here don't pay tax, yet the government still have enough money to give away back to the tax payers (for the one who pays), this is unheard of in UK.

Will upload some of my new work on my portfolio soon.

Re: The Fundamentals of Photography

The picture I used above was an example! However, it somewhat shows the effect that I wanted. I realize it may have been caused by a lens hood, but it's the vignetting that I wanted to learn how to do.

Mask out the shape you wanted with the lasso tool on a new layer, feather then fill it in with black will give you the same result.

Re: The Fundamentals of Photography

I still think that those particular shadows were caused by a butterfly hood and not by any image editor

Re: The Fundamentals of Photography

Patrick... thanks for your reply. I had some troubles with the site and wasn't able to get on here for a while. I completely forgot about this post until now.

I just tried your suggestion in CS4. I've got everything up until the "go to levels or curves" part. After I use the lasso tool, I clicked on the Levels and Curves options, but it didn't give me the look I was going for. I then clicked on "Refine Edge" and it gave me exactly the result I wanted. However... once I click "ok", I lose all my settings and it goes back to my lasso selection. Any suggestions on what I'm doing wrong??

Thanks again.

Hi
The effect on this picture could be easily done in photoshop using the lasso tool. Lasso the area to be darkened then feather to the amount required (Select>feather, in CS4 Select>modify>feather) go to levels or curves and darken to the way you want it. Others may give another method, as you will learn with photoshop there are always at least half a dozen ways to do anything.

Re: The Fundamentals of Photography

Thanks Patrick.... I looked up vignetting and I don't think that's the term I'm looking for. I tired to find you a picture that would describe what I'm referring to and unfortunately this is the best I could come up with. This picture was not taken by me... I found it on Google.

The original picture I had seen with the partially closed shutter was a wedding picture and it was a great photo! Unfortunately I can no longer find that picture. Hopefullly this gives you a better idea of what I'm looking for.



Graham - Thanks for the additional tips!! I'll take any extras you feel like throwing out!

What is puzzling me is your description of a half open shutter, the only time an exposure can be made with what appears to be a partially open shutter is when a camera fitted with a focal plane shutter is used with the incorrect shutter speed and flash. For example if the camera is made to sync with the flash at a maximum of 1/125 and 1/250 is used then only part of the frame will be exposed because the second curtain has started to close. This will block exposure to part of the frame. A horizontal shutter will block down one side and a vertical will block from the top, if a higher shutter speed is used then only a small slit would be exposed, and a very fast shutter speed and nothing will be exposed.
A technique which is interesting to use are is a very slow shutter speeds when using flash. If a moving subject is photographed with flash and a shutter speed of say 1/10 or even longer is used, a sharp image is captured but because the exposure continues after the flash a blurred trail is also made this can be very effective. Some digital DSLR's give an option in the menu called 2nd curtain sync, which gives a similar effect.

PS be very careful posting other peoples pictures to this or any other forum without permission, copyright is owned by the author. If you want me or anyone else to see a particular example to illustrate something point go to the the site and picture by using the address. Easily done simply go to the picture or article and copy & paste the address from the top of the screen (select> right click> copy, to paste right click> past to where you want it) the resulting link will appear on your post, the reading can then double click it and is taken to the picture or article, this way no copyrights have been infringed. This only happens with focal plane shutters, leaf type shutters will sync at any speed.

Re: The Fundamentals of Photography

I wonder if that could be the lens hood causing that shadow!

Not sure this is what you are asking about, darkening of corners is nothing to do with the shutter, its called vignetting and can be caused by a number of things.

If this is not what you are asking about then can you point me/us to the image on-line that you are referring to.

Re: The Fundamentals of Photography

I found this thread while searching for some tips on the site. When I read the 1st post, I thought "What a great idea! This thread will be perfect for me as a beginner photographer!" I was a little disappointed when I continued reading to find that there were only 2 posts following Graham's initial one. I think this would be an excellent place for all you experts out there to post your tips, ideas, and thoughts on how to get unique and creative photographs... and maybe teach us beginners a thing or 2!

Looking forward to your responses and maybe some other new ideas as well!

I really appreciate that comment. Thank you.

I too was disapointed that with so many good photographers contributing to the site that we didn't get anything like the number of comments I had hoped for and even less "Top Tips"

I know it's stating the obvious but my number one is always have a camera with you, that is set ready to go with charged batteries and an empty card. Sometimes opportunities present themselves for a very fleeting moment and not being able to work quickly often results in a lost shot.

Knowing how to use all the functions and modes that you need to use with a high level of familiarity would be high on my list (I've heard many times people cursing that they can't remember how to get it to do whatever they want )

A lot of the basics: Focus, Composition, Exposure, etc, etc, will have some people saying one is the most important and others voting for something different. Such is the nature of photography that a simple thing as "The rule of thirds" is for some a fixed and always adheared to principle while other will deliberatly break it to present a dramatic difference.

When it comes to "Natural History" type images few will argue that there needs to be in the image the ability to identify the subject, to have it in its environment and if posible show it doing its thing

I still believe it to be a good idea, but it is not something that will just happen, it needs "manageing".

Perhaps someone can start by helping me out with this one. I've seen photographs where it would appear the shutter was only half open when the picture was taken, resulting in 2 of the corners being dark from the shutter. Is there a way to do this with your camera or is this a Photoshopped image? And if there is, how do i go about getting that style of picture? Is there a name for this style of picture?

Looking forward to your responses and maybe some other new ideas as well!

Hi

Not sure this is what you are asking about, darkening of corners is nothing to do with the shutter, its called vignetting and can be caused by a number of things. A cause on digital cameras is the use of a lens designed for APS size sensors on a full frame digital camera, the lens cannot cover the whole area.
It can be caused my the addition of round filters to the camera lens particularly wide angle lenses. Caused in these ways its considered a fault as its not really under control of the photographer.

However for artistic reasons it is introduced in editing software i.e. Photoshop or if film is still used in the darkroom, but under full control of the photographer and therefore in exactly the way he/she wants it..
The idea being by darkening the corners it makes the viewer look at what the photographer intends you to look at.
There are a number of ways of doing it in Photoshop, the one I use is to lasso the area I want to draw attention to, feather by between 200 & 250, invert the selection and using levels darken down.

If its very heavily done on a lighter image it can be too much, so care should be taken.

If this is not what you are asking about then can you point me/us to the image on-line that you are referring to.
