Experts help me please, I could't recreate in rendering as the product shown T_T

I thought I would show you the effect of focal length on the shape of a character's face.  A single figure plus a HDRI  Plus a single light at 35 mm, 85 mm,  and 185 mm: 

Note how the face changes shape.

I'm not understanding your point. You probably wasted quite a bit of time trying to copy the promo render to do? Are you trying to say or prove that the character in the promo isn't the same one you purchased? I can assure you that it is, and I can also guarantee you that none of my renders of characters that I purchased look exactly like what I see in their promo images. If you want an even bigger shock, try using different facial expressions on them and render it.

Trust me, you'll have more fun and a lot less frustration doing your own thing rather than trying to copy a promo image.

Thanks for your comment

have you read post #6?

many thanks

Please stop asking if people have read post #6 - aside from the ambiguity, since posts are not numbered, and the fact that it isn't clearly relevant to the replies you need to remember that you are asking people to take the tiem to help you and conduct yourself accordingly.

It's not the character. Here is Ichigo. You can easily see that the head/face are the same as the promo. Don't blame the product.

Not sure if you keep referring to the sixth post in the thread, or your sixth post. Regardless, IMHO your image and the original image are the same character and hair. As others have noted, the camera angle is different (and no doubt your camera settings are different as well). but most important in my mind is your lighting is much different. While you have closely matched the position and shape of lighting highlight under her left eye, It has a much more defined edge in your image, indicating your light source (or sources) that are creating this are much smaller, creating more defined edges. By increasing the size of your light sources, you will reduce the harshness of the shadows. From your examples, the rest of the lighting looks to me to be completely different. IMHO the contour of her jaw is different due to the differences in the lighting, not the model (The image posted by fastbike helps support this opinion). Very minor differences in lighting can have a dramatic effect highlighting or masking different features on a model.

Look carefully at the left side (shoulder) of the model in your render, vs the same area in the original (posted below for easy reference). The light/shadows are completely different, the same is true for the light on her neck. Your lighting is illuminating her entire jaw line, while in the original the jaw line is in soft shadows. In your render the shadow on her chin is very harsh (and in a slightly different position) than it is in the original, which is also making the geometry in your image appear slightly different than the original. As others have mentioned, part of the difference in the soft focus effect in the original compared to yours is due to your harsh lighting. Buy increasing the size of your lights you will soften the lighting. Just the soft vs harsh lighting issue in the two images is a huge part of the perceived differences in the model (making the geometry in your render look much more angular/defined than in the original image). Increasing your pixel filter size in Iray may also help with the soft focus effect (or you can take your image into your preferred image processing program, copy the image, paste it as a new layer on the original, apply a mild Gaussian blur to the new layer, then adjust it's transparency/opacity to the desired level, and instant soft focus without repeated adjustments in Iray to get the proper level of soft focus).

Good luck, matching the camera angle, camera settings, and lighting in an image can be quite difficult.

Thank you very much everyone's help, eventally got it, special thanks to Catherine3678ab, I finally got the effect of what I want, admitted I missed out some skill on lighting, really learn a lot of things this time. Many thanks again everyone.

Wow, fastbike1 your rending is very nice, even better than the promo, so nice, so nice.

would you mind teach me?

would you mind let me buy your scene from you? so that I could learn from that and improve myself.

many thanks, great thanks

Your RENDER looks Much better.. Wow

 

 

 any expert tell me what have I done wrong or missing, many many thanks.

I brought :

CO Ichigo and Ichigo Hair for Genesis 8 Female(s)

https://www.daz3d.com/co-ichigo-and-ichigo-hair-for-genesis-8-females

I have try to render it in a way to get back the figure they shown but no luck, in the attachment shows an highly simular position and lighting, but I found that she does not look like/same as the promotion picture, I would wonder why? Have I done something wrong? missing any thing?

even the outcome looks not bad, but it looks obvious to me they are two different person, and also missing some feeling and soul, seriouly want to ask for advise from expert here, many many thanks in advance.

also, it would be great if Crocodile Liu could give advise on the parameters and such, so that I could recreate what they selling, many thanks in advance.

Finally, I would like to say, I buy a lot of models, they may be simularm but they can be differentiate in human sense. 

I would expect it is easy for me to able to recreate figure especially on their face, if I unable to get the face I intended to buy, all my buying may mix up or duplicate, because they only have subtly little different

-------------------------------------------------------------------------------

oh, you may say just try to blur it, yeah, have done that, no luck, also have attached that for reference, you can tell they are different person

why I broder to post? Oh, because I was about to buy some other new product from them, I like it but ... ... what if I don't get what I see from what I buy, or also is good to found out: "did I do any thing wrong / missing anything?“ after so many years of using DAZ3D, many thanks to reading all these till the end, thanks again and looking for your comments.

%ps also wonder if it was render by other software, and I will never get it from Daz3D, if so should have tell me earlier  T_T

Glad you were able to get what you wanted! Your latest version is outstanding.  Lighting is extremely important for great renders, proper shaders are also very important. The artists who sell content in the store do most of the shader work for you, but after you master lighting, you may want to learn more about shaders to improve on the base they give you.

@turtle_s So, whats the recipe for the lighting?

many thanks, you guys coments are very helpful, helps me a lot and I learn lot from that, may be beasaue I was started Daz3D on long time ago (V3 / V4), lighting system was quite different at that time, I missed a very big part. Anyway, thanks again, still have a lot to learn, I think I must keep learning to keep up, many thanks

let me check,...  a Dome (evn. int. = 4) with a sun (int. = 0.3) + 8500k very light purple blue distancelight on left + 8500k white distancelight on right

by the way, just wonder anyone know:

is there anyway to contact a particular artist in the daz shop? any way to contact them?

If they're regulars in the forums you can contact them there.

Otherwise, there's no direct way to do that. Part of the agreement vendors have with Daz is that Daz handles customer requests so that vendors can concentrate on creating more content.

so, is that means if I want to negotiate with the artist, I better contact or negotiate with Daz?

(i.e. buying all product from the artist but have it with all promo sence attached)

Leana

Considering that vendors often use products from other vendors or from other stores (or even older products not available anymore or totally custom content) in their promo pictures, or may hire other artists to do their promo renders, the chances of them selling you their promo scenes is very slim IMO.

You can try opening a support ticket to ask, but I wouldn't hold my breath.

If you don't understand photographic lighting to some extent, Iray rendering will be tedious, If you understand lighting and don't do a lot of postwork, rendering is pretty straightforward after you decide what you want the scene to be.
