Exposing images
1

Hi guys,

In the morning, I have filmed these two pics using my Lumix G7 with a 14-42 mm kit lens.

Two images are post-processed in Adobe photoshop and are shown below.

Is the first image is well exposed? What about their composition of two images?

Also, shoot your opinions about my post processing. Can you feel any differences between those images?

Kindly give your suggestions.

Re: Exposing images

The exposure is decent, however on the second shot especially I would probably have sacrificed some shutter speed in favor of a lower ISO. Also a bit of fine sharpening would crisp the shots up some.

Whether the first image is well exposed or not is a question that I cannot answer without more information. Can you show the histogram as it was before any post processing. It is not clear whether it can be improved; that will depend on whether you have given the highlights full exposure.

The exposure of the second image looks okay, as there are no strong highlights. But at least theoretically the ideal exposure of the raw image would have increased exposure, shifting the lighter pixels to the far right side of the histogram. Of course, the brightness would be reduced in post to render an appealing image.

They came out well. I would say they are four images - two of a flower, and two of a leaf.

Two images are post-processed in Adobe photoshop and are shown below.

Is the first image is well exposed?

I don't see any issues with exposure with any of them. The second leaf shot is just a bit soft, if you're pixel peeping.

What about their composition of two images?

Fairly boring subjects put smack in the middle. The second flower is a bit better cropped, but still very much centered so there isn't much to say in terms of composition.

Also, shoot your opinions about my post processing.

Nothing out of the ordinary. The second flower looks like you recovered some of the highlights well. I would probably have added a mysterious vignette or something to raise the level of excitement.

Can you feel any differences between those images?

Can you feel the beat...

Kindly give your suggestions.

May the force be with you...

This is the histogram, before post-processing of flower .

Re: Exposing images

Can you give some tips for composing a flower instead of too much centering ?

Search online for 'rule of thirds' - this is one way to get started with non-centered composition. Don't get me wrong, centering something frequently works well, and sometimes is really the only good option. Doing everything along thirds is just as bad as centering everything. My recommendation is to take lots of different images and see what you like most. Repeat that daily or weekly and over time, you will get a good eye for interesting compositions.

For example, try to find more than one flower/leaf and place one as your main subject, and a second/third one as an out-of-focus silhouette, or color splash...

Take a wide angle lens and show some of the surroundings to add interest...

Take a spray bottle and add some water drops (lol)...

Take lots of shots and throw out 95% of them, making mental notes what they lack and what to try differently next time...

Most of all, have fun! 🤪

Just a silly shot of weeds from my garden. No rule of thirds applied really. Maybe a bit too busy? Luckily, always room for improvement.

BTW I like how you backlit your flower to make it "glow", that's really attractive.

Very good. The histogram shows nearly perfect exposure. Good work.

It’s ok if the source image is an OOC JPEG but not if it was a raw image. The histogram is after WB coefficients and gamma correction.  The only good way to determine if the raw image was optimally exposed is to review the raw histogram. That requires a tool that displays raw histograms like Rawdigger. In all likelihood the second image was not optimally exposed for raw if it was exposed using Normal metering with no positive exposure comp applied.

Me too!

If you are going to give advice, I'm not sure that this is a good example.

The two main flowers are good, your comments, fine, as well. BUT the part flower in the top left is a distraction and could have easily been elimiated by cropping a bit off the top and a bit off the left side. That would also get rid of the leaf in the bottom left. (Yes, I know you were talking 'thirds' but we don't want to confuse a newbie!

Awww. Ok. Thanks for your thoughts... appreciate it. There are always a lot of different ways to look at and process images, and like I said, loads of room for improvement.

Square-er crop to eliminate the distracting (exciting?) partial flower. This also puts the center of the main subject on one of the thirds. Unfortunately, the third flower also balanced things a bit so now it feels like there's too much empty space on the right.

Anyway, back to the OP!

I agree, but some more selective trimming would compensate.  Another local photo judge and I each found ourselves saying the same thing: "I've never seen a picture that wouldn't be enhanced by some subtle vignetting!"

BTW I love the subtle colours in the open flower!!
