Having good, sensible and appropriate rules is important, I can agree on that. Personally I would like the strict focus on Pentax to be relaxed but I can see the difficulties as well e.g. just wait for users leaving Pentax to enter into eternal arguments justifying their leaving and posting up 'supe...

I thought deletion of threads and posts without explanation was a thing of the past, I thought the forum was starting to become normal again? Quiet yes, but back to normal. Also John what is trolling, a word or phrase I am not aware of? And one last thing can I talk about and post photos taken...

Working with HSV images- any GIMP experts here?
The way I see it. So split the colour from the light. Do a BIL filter and take the smoothed layer. Take the IR version, BIL fliter , find the difference and take the detail. Add the IR detail to the colour light base. Add the colour layer back. You can get an add on BIL script for ...

Macro
First question, what lenses have you already got. Have a search on the site for previous threads as there will be lots of threads similar to this. AF is more expensive but you will probably need to MF so don't worry about autofocus. 1. Extension tubes on a decent prime lens. For example ...

Macro
Do some reading on focus stacking also. The 50mm Prime and macro tube approach can deliver an incredibly narrow focus point, which depending on what you're looking to photograph may be too small for you. Focus stacking allows you to 'walk' the focus point along an object as you take several sh...

Outdoor pin up shoot
Stuart, no idea what lenses you have, but if you have any of the following they would be good. Any of the 50mm f/1.8 lenses DA* 50mm-135mm DA* 55mm Hope i am not teaching you to suck eggs? Ideally you want to separate the model from the background, so any lens in the telephoto range will hel...

Photoshop Elements boxed or on subscription??
I use the £8.78 subscription of CC, already had Lightroom which I got at a good price although I use it very very rarely. If/when the subscription price doubles I'll probably revert to PS5 and perhaps start getting my head round Lightroom, also have PSE12 to fall back on. There are free trials of mo...

Need some help with regards to shooting wide open
If you have arrived here because you love shooting wide open all day long and composing then this is the question for you... I am (im sure youve noticed) shooting a lot of portraits at the moment and for quite a while I thought my "new" DA* 50 135 was focusing incorrectly at wide apertures when f...

Need some help with regards to shooting wide open
I tend to focus and re-compose, a minor movement will make very little difference unless the distance from the focal point is altering, which for portraiture it should not move very much. I would check the AF fine adjustment Alistair, I have had to dial in '+5' on my K-3 with the DA*50-135 and it...

Need some help with regards to shooting wide open
Portraits need us to focus on the eyes, unless there's a reason to change that such as the famous shot of the boxer, concentrating on his huge gloved fists. There's not much DOF at wide apertures, so the subject moving and the photographer moving can easily throw the focus point out. Just keep sh...

Need some help with regards to shooting wide open
I find if I want to nail the eyes, then its best to get the centre-point onto an eye, focus and hold - then move to compose and fire, and all quickly. If you get a few goes it usually helps, and a bit of a burst can help also if there's slight movement, you should get one good hit. I get good res...

Focussing on the eye will lead to miss focus as the front of the eye is clear the camera will actually focus on the rear of the eye ball. Instead focus on the eyebrow, sharp brows always show sharp eyes.

I would agree that the chances of an AF sensor being small enough and the photographer accurate enough to have the AF focus on the back ofthe eye to be exceedingly slim. As for my f/1.2 shots of the lady, no she didn't beat me to a pulp afterwards :)

I think what was being said here was not that it was the photographer who was specifically focussing on the rear of the eye 'assembly' - but rather that when the photographer tries to focus on the front surface of the eye the focus point ends up in fact at the back of the eye (MattyH's Macula & Folv...
